INTRODUCTION

The SIM231 family of Serious Integrated Modules is a series of complete intelligent 3.5" QVGA graphic front panels, some
with resistive touch capability.

The SIM231 family incorporates Serious GatlingTM Technology for rapid-fire
delivery of pixels to the display with minimal CPU overhead while retaining the
cost-effective elements of a solution without a dedicated hardware graphics
controller. Using this technology, the SIM231 can deliver 16 or 24 bit color
frames to the LCD with little CPU and SDRAM bandwidth required.

These cost-effective modules are designed for use by Original Equipment Manufacturers (OEMs), custom design shops, and
hobbyists to add sophisticated and user-friendly graphical user interfaces to their products.

USAGE MODELS

In most cases, you will be adding a SIM to a system that already has an MCU, I/O, power conditioning, and other custom
interfaces. Perhaps your system already has a membrane keypad and a 2x16 character display or indicator LEDs. Your
current MCU software in your existing system controller manages all aspects of your device, including (as applicable) belts,
pumps, motors, servos, indicators, etc.

Rather than completely redesigning the hardware and software of your existing system to create a merged
hardware/software architecture (LCD front panel plus system controller all-in-one), it is far more common to partition the
problem by retaining your existing system controller and software and using the SIM as an intelligent stand-alone front
panel.

Therefore SIMs typically most often used as stand-alone front panels responsible for managing just the Human Machine
Interface (HMI) in a larger system. The existing, separate, device-specific system controller continues to manage the main
functionality of the system. SIMs are equipped with several methods for simple interconnect to the external system
controller, getting power from that external system, and communicating via a serial type link (SPI, UART, USB) to that
controller to exchange data and commands.

Using the Serious Human InterfaceTM Platform (SHIP), the software team can leverage the power of the SHIPTide rapid GUI
development tools from Serious, developing a user interface in as little as a few hours and a few dozen lines of code. The
SHIPEngine runtime firmware pre-installed on all SIMs takes care of all the drivers, rendering, communications, and event
handling for the user interface, leaving the GUI development process to be focused on look and feel and differentiation of
your device. You never need to write C code or use a JTAG debugger with a SIM to develop a modern-looking user
interface.

SHIP software and development tools are available at no-cost for users of Serious Integrated Modules.
See www.seriousintegrated.com/SHIP for details.

Adding a simple software protocol driver to your system controller on the other end of the communications link allows
your controller to communicate with the front panel. You can then architect inter-board messages such as "pump is on"
which could be sent over the UART/SPI/etc. causing visual indicators to appear or change on the display. A GUI on the
SIM231 could change user preferences, for instance, sending back messages such as "pump on days: MWF" which the
system controller may store in its configuration EEPROM.

The possibilities are endless: the SIM231 module contains not only a powerful MCU but also a suite of hardware features
that are commonly needed in many designs. An alarm panel, for example, could be as simple as a SIM231 connected to
another PCB with a $0.20 MCU, a few relays and a battery.

HARDWARE

SIM231 family features include:
        4.3" WQVGA 480x272 color TFT display
            o Various touch panel options, including 4-wire resistive with proximity detection
            o Color depths from 16 to 24-bit
            o Serious GatlingTM Technology for rapid-fire pixel delivery to the LCD with minimal CPU intervention
        100MHz 32-bit Renesas RX631/RX63N MCU
            o 128KB RAM, 512KB-2MB FLASH
            o Integrated temp sensor & RTCC
            o Ethernet RMII available on expansion connector on some variants
        On-module memory
            o 8-16MB SDRAM
            o 8-16MB serial FLASH + 4kbit EEPROM
        Extensive I/O
            o 60-pin Expansion Connector (GPIO, +5V, RESET#, I2C, SPI, UART; RMII on 63N-based units)
            o Serious system-to-system 16-pin Power/Communications Connector
            o SHIP Programming Port for rapid GUI/Firmware programming
            o USB Micro B Device Connector
            o USB A Host Connector
            o Tag-Connect JTAG Port
        PCB operating temperatures as wide as -40 to 85C; LCD option may restrict operating range.

Within the SIM231 are numerous family members, or "variants". Each variant has a slightly different set of features and
price points for an OEM to select the appropriate feature/cost point for their specific application. Consult the Variant Table
for more information. In addition to these different functional variants, various LCD options are available.

SOFTWARE

Developing a complete graphic user interface (GUI) can be a complex, time consuming, and expensive endeavor. Often
tens of thousands of lines of custom C code need to be developed in conjunction with custom hardware drivers and off-
the-shelf libraries. For rapid GUI development, the Serious Human InterfaceTM Platform offers PC-based GUI design tools
and rapid GUI prototyping, development, and deployment. With minimal coding you can create attractive and functional
GUIs in a fraction of the time of C-based development.

SHIP software and development tools are available at no-cost for users of Serious Integrated Modules.
See www.seriousintegrated.com/SHIP for details.

The SIM231 is also supported by a growing collection of Renesas, open source, as well as Serious proprietary software,
allowing designers to gain confidence that their essential software can not only get it done, but perform to the needed end
result. Available at mySerious.com for download, SIM231 programmers can obtain an out-of-the-box experience with pre-
ported versions of the Micrim uCOS-III, Segger embOS and FreeRTOS operating systems. The SIM231 includes full single-
unit production licenses of the Micrim and Segger kernels for use with each module.

It is very difficult to know, as a designer selecting the hardware for a graphic/touch interface, if the result after many
months of software and graphic design will have acceptable performance. Will the system be responsive? Will it be visually

attractive? Will the look-and-feel be consistent with the company's brand image? Serious addresses these OEM designer
challenges by delivering video best-of-class GUI examples, fostering community demos and solutions, and providing
software, tools, and consulting services.

GETTING STARTED

The SIM231 comes pre-configured with a SHIP demo loaded into the in the RX MCU and serial FLASH.

If your SIM variant has a USB Micro B connector present, your SIM can be powered from any PC's USB port or USB hub with
500mA power capability.

Alternatively if you have purchased a development kit containing a SHIP Programming Adapter 200 (SPA200) and SHIP
Programming Connector SPC200, you can plug the SPA200/SPC200 combination into the SHIP Programming Port with the
SPA200 powered from a PC USB port, hub, or even a stand-alone USB AC power adapter.

Several connectors may be used to power the SIM231. See Power Supplies.

The demo will start running and displaying info on the LCD screen. For more getting started information and out-of-the-
box tips, see www.seriousintegrated.com/oob.

Note that the PCB, MCU, and associated components may be rated for a larger operating temperature range than the LCD.
In this case, the MCU will operate correctly over the entire operating range however the LCD may not function or be visible
outside its specified operating range. In all cases, the narrower of the two recommended storage temperature ranges (PCB
and LCD) should not be exceeded.

DEVELOPMENT KITS

The SIM231-A01-DEV-01 development kit contains everything needed to develop with, and production program, all
members of the SIM231family.

             Some variants of the SIM231, such as the SIM231-A03 and A04, have no USB device connector populated you must have
             a SPA200 (included in the development kit) to be able to program and update these modules.

             The SIM231 is primarily intended for GUI development with the Serious Human InterfaceTM Platform therefore the standard
             development kit has no JTAG debugger included. To develop in C, you must purchase separately:

                 a JTAG debugger, such as a Segger J-Link with J-Link RX Adapter or Renesas E1
                 a Tag-Connect TC2070 adapter cable and retention clips

The kit contains:
   SIM231-A01-R32ALM module
         Superset of all SIM231 features
         Bright 300+ NIT Resistive Touch Multi Viewing Angle LCD with proximity and ambient light detection
   SHIP Programming Adapter 200 (SPA200) Kit
        SHIP Programming Adapter 200 (SPA200) intelligent rapid-programming unit for development and high-volume
         production use
        SHIP Programming Connector 200 (SPC200) to connect the SPA200 to all newer SIMs, including SIM115, SIM231, and
          SIM535
         All cables necessary to connect the PC to the SPA200, the SPA200 to SPC200, and SPC200 to the SIM
         5V 12W wall power supply for lab use (110/220VAC EU/US voltage and plug compatibility) powers the SPA and optionally
          powers the SIM as well
   16 pin wire harness (JST16 plug one end, tinned the other) for lab cable enabling
   Acrylic "enclosure" for safe handling and demonstration use

The SPA200 and SPC200 are set for release in Q3 2014; Development kits shipped prior to this release will include a mail-in
coupon for these.

BY SUBSYSTEM

The amount of power necessary for SIM231 to function is highly dependent on how and which features of the module you
use. This is especially true for major power consumers such as the LCD backlight and USB embedded host port. If your
application does not enable these features, the typical and maximum power numbers can be appropriately subtracted
from the maximums for the SIM respectively. Assuming typical switching conversion efficiency, the power breakdown of
the elements is as follows:

        Subsystem                       Circuit-Local Power                               +VEXT to Local    +VEXT Power Required

MCU I/O

Many I/O signals on the SIM231 are directly and exclusively connected to RX63N/631 MCU pins. Consult the RX63N/631
data sheet for complete specifications of each pin.

            There are specific power limitations on the MCU pins. Consult the RX63N/631 data sheet for more information. Exceeding
             these limits may damage your board, damage attached systems, overheat or cause things to catch fire.

AC TIMING CHARACTERISTICS

The AC timing characteristics at the module level are governed by the underlying AC timing characteristics of the
individual components. Consult the component data sheets for more information.

             The no-cost SHIPWare source code as well as the full-featured Serious Human InterfaceTM Platform software initializes the
             MCU and other SIM components for correct operation.

ENVIRONMENTAL CHARACTERISTICS

The following table describes the absolute maximum environmental conditions for the SIM231:

Operating Temperature (not including LCD)                     Min Typ  Max                   Units
Storage Temperature (not including LCD)                                                        C
Humidity                                             All -40           +85                     C
                                                                                              RH
                                                     All -40           +85

                                                     All               90% below 50C

                                                                       60% above 50C

Note that these limits do not include the LCD environmental limits. For example, while the SIM may be able to function over
its full operating temperature range, often the LCD temperature range is more restrictive and the LCD may become difficult to
read, sluggish, or non-functional outside its limits.

Consult the LCD Options to determine the operating and storage temperature limits for the LCD selected. In no case should
the unit be stored outside the narrower of the Storage Temperature ranges of the SIM and its LCD.

HANDLING AND CARE

Observe the following handling and care guidelines.

HANDLING

            Be very careful when handling the edge of the SIM where the flexible cable from the LCD panel is exposed. This
            can be easily damaged or ripped if shear-force is applied in handling.

Do not attempt to disassemble the module or solder components or wires to the module; this may render your
board non-functional and void your warranty.

As with all electronic subsystems and circuits, observe proper ESD handling procedures.

As with any glass product, use reasonable care when handling to avoid glass chips and cracks.

If the LCD glass breaks and the LCD liquid materials escape, avoid contact with bare skin. Wash exposed skin
with soap and water immediately and dispose of the product according to local materials handling procedures.

If the SIM comes in factory packaging with a protective cover sheet on the LCD, it is advised to leave this
protective film in place until the SIM is mounted in the final assembly to prevent scratches and fingerprints from
marring the display surface. Do not expose to high temperature and/or high humidity testing with the protective
sheet place. Slowly remove the protective sheet to minimize potential static electricity creation.

PRESSURE AND IMPACT

            On non-touch variants apply no pressure, and ensure no impact can be made by end users, to the surface of the
            LCD display. There is no specification for pressure or impact on non-touch LCDs.

On touch variants, do not use sharp objects to activate the touch screen or the overlay material may be damaged.

Do not apply any bending/twisting force to the LCD or the SIM PCB or the unit may be permanently damaged.

STORAGE

Follow these basic precautions when storing un-installed SIMs for extended periods:

     1. Store SIMs in the original factory packaging whenever possible. The sealed polyethylene antistatic bags or the
          antistatic trays are designed for long term storage.

     2. Store the SIM sub-packs where they will not be subjected to high heat, sunlight, or high humidity conditions.
          Recommended storage temperatures should be kept between 0C and +40C, with relative humidity below 80%.

     3. Desiccant should not be required if properly sealed and room temperature ambient temperatures are maintained.

CLEANING

If cleaning of the LCD panel surface is necessary, Isopropyl or Ethyl alcohol, either 100% or mixed 50%/50% with distilled
water, may be used on a moist clean soft cloth.

            Do not use abrasive, ketone-containing, and aromatic solvents which will damage polarizer materials.

PHYSICAL CHARACTERISTICS

The outer dimensions of the SIM231 are approximately 121.6mm x 67.3mm. Note that for those variants with USB Micro B
and/or USB A connectors populated, these connectors extend approximately 2mm beyond this width. The depth of the
module depends on the variant. For example, variants with resistive touch screens have the cover glass and touch layer on
the LCD that increase depth by over 1mm. Also, various connectors such as the USB A connector, if populated, change the
mechanical dimensions. An example of the SIM231-A01-R32ALM module dimensions are shown here:

Dimensional drawings and complete 3D STEP models are available for most SIMs, including the SIM231.
Visit www.seriousintegrated.com/docs for more information.

ALIGNMENT AND MOUNTING HOLES

There are four (4) 3.50mm holes by which the SIM should be attached into a chassis. Four M2.5, M3 or similar screws into
correctly-sized standoffs from the inside of the bezel assembly will be more than adequate to firmly hold the module. The
holes are over-sized from the typical screw in order to allow tolerance for standoff positioning as well as to ensure the
module can be arranged to perfectly center in the bezel's opening.

Rather than attempt to tighten the screws while manually/visually positioning the module in the bezel opening, all SIMs
include reference alignment holes to ensure perfect alignment within your bezel. Locate the several 2.05mm holes on the
mechanical diagram any two of these are meant to accommodate simple non-threaded alignment pins precisely
positioned on the inside of your bezel. The SIM can be initially inserted onto the two precision alignment pins, thereby
centering and positioning the active area of the LCD in your bezel, and then the four mounting screws can be inserted and
tightened.

If your chassis is molded plastic, you can extrude very slightly tapered pins for this purpose. For metal bezels, off-the-shelf
pins such as the PEM Engineering MPP series of self-clinching pins can be used. Depending on the tolerance of your
insertion process of the pins into the metal bezel, you may want to undersize these pins to 1mm or 1.5mm, recognizing
that the tolerance will slightly affect the consistency of the LCD positioning.

LCD DIMENSIONS AND BEZEL SIZE

The LCD glass positioning is a critical element for correct location of the display within a bezel. This positioning is well-
defined in the Mechanical Design Package (MDP) for the specific variant, and should always be referenced relative to the
center of the active pixel area of the display. Note in the diagram above the "C" designator which does not indicate the
physical center of the LCD module or the SIM, but rather the center of the active pixel area of the LCD display. The MDP also
shows a diagram similar to the following (from the SIM231-A01-R32ALM MDP):

These two diagrams are critical for correct bezel design. The acronyms in the above LCD diagram are as follows:

   FO: Frame Outer -- outer dimensions of the physical LCD display module
   TPO: Touch Panel Outer outer limits of the resistive touch panel material
   BI: Bezel Inner inner limit where your bezel should be contacting the surface of the touch panel & LCD display with
    any gasket and not adversely affect touch performance
   TP V.A.: Touch Panel Visual Area conductors from the touch panel are no longer visible inside this area; your bezel
    will extend and cover to this dimension
   TP A.A. Touch Panel Active Area start of the active area of the touch panel, which may extend slightly outside the
    active area of the pixels
   LCD AA: LCD Active Area -- active pixel area of the LCD display; you will want to ensure visually the center (C) of this
    active area is centered in your bezel opening and that all the active area is visible to the end user

DAUGHTER CARD PHYSICAL GUIDELINES

             This section is provided as a helpful overview only.
             The authoritative mechanical reference is the SIM535 Mechanical Design Package (MDP), which includes 2D drawings and
             STEP models, and is available for download at www.seriousintegrated.com/docs.

Most new SIMs across most of their variants include a 60-Pin Board-to-Board Expansion Connector. These variants also
include six M3 threaded standoffs (PennEngineering SMTSO-M3-4-ET or similar) to firmly support and attach a daughter
card at the correct 4mm board-to-board distance.

             Serious reserves the right to substitute components and/or change component layout on SIMs at any time without notice.
             Exceeding the height envelope described below with the assumption of specific SIM component used and/or placement so as
             to utilize the inner-stack-height for daughter card components may cause mechanical conflicts in future SIM revisions.
             It is possible to create a single daughter card that can dock into numerous SIMs, including the SIM115, SIM231, and SIM535.
             Consult the respective Technical Reference Manuals (TRMs) to validate a compatible footprint: there are slight differences in
             the physical and electrical characteristic for daughter cards across different SIMs.

The board-to-board distance with this connector (when used with an identical mated connector) is only 4mm, enabling a
daughter card to be developed with a very low overall combined profile. For components on the side of the daughter
card facing the SIM, observe the maximum component height zones on the SIM your components may extend only 4mm
less this distance on the SIM-facing side of your PCB:

                            Example SIM231-A01-R32ALM Max Height Zone Map

For example, in the yellow shaded area above, the components on the SIM535 are less than 2mm total height, leaving
(4mm board-to board) minus (2mm yellow height zone) = 2mm for components on the SIM-facing side of a daughter card.

Note that component data sheets typically indicate the physical height of the component which is not necessarily the same
as the total height of the component after soldering, which may slightly raise (or even lower, in the case of some BGAs) the
component.

For prototyping, any M3-0.5x6mm pan head or cap socket screw can be used to attach a daughter card to the SIM. For
production units, the recommended screw and assembly torque specifications for attaching a daughter card are as follows:

Small quantities of this type of screw can be readily purchased from McMaster-Carr (93705A813). Production volumes are
readily available from many suppliers, including part number .30C60MRPS/NPAT from North State Fastener, Inc.

Do not apply excessive torque to daughter card screws into the threaded standoffs or they may tear from the PCB and
permanently damage the SIM.

Do not use screws longer than recommended or the screw may apply force to the back side of the LCD panel and
permanently damage it.

SERIOUS COMMUNICATIONS MODULES

Serious is in the process of releasing several new
communications daughter cards designed to dock into the back
of the SIM115, SIM231, and SIM535 as well as some future SIMs.

The Serious Communications/Power Module 117 (SCM117)                SCM117 Docked
family, for example, is a series of flexible and production-worthy  into the SIM231
communications and power conversion accessory boards for
use with Serious Integrated Modules (SIMs). The SCM117 can
dock directly into newer SIMs such as the SIM115, SIM231, and
SIM535 forming a low profile and cost effective combination.

The SCM117 family has numerous members, or "variants", implementing all or a subset of the following:
   RS232, RS422, RS485, and CAN transceivers
   Renesas RX111 MCU for local protocol translation and control
   DC-DC converter for powering the SCM and attached SIM from network-borne power

                                        The SCM117's most basic functionality is to provide network physical layer transceivers
                                        from the network cabling (RS232, RS485, RS422, or CAN) to the SIM, as well as network
                                        power conversion from whatever voltage (+9-25VDC) is available on the network cabling
                                        to the 5VDC required by the SIM and SCM.

                                        Variants with the RX111 MCU place the RX111 in the middle of this conversation: the
                                        RX111 can communicate with the SIM using one protocol (for example, Modbus or the
new SHIP Bridge protocol) and another protocol on the network (for example, your own proprietary protocol).

For more information on the SCM117, see the Serious website.

Not all features are available on all SIM231 variants (family members).

HIGH PERFORMANCE RENESAS RX63N/631 MCU

The heart of the SIM231 is the 32-bit Renesas RX63N/631 microcontroller (MCU) with 128kB of internal RAM, and zero wait-
state internal execution FLASH. This powerful MCU is equipped with extensive analog and digital peripherals and, with
software, can deliver an excellent user interface experience.

GRAPHIC COLOR LCD DISPLAY AND TOUCH OPTION

The SIM231's Liquid Crystal Display ("LCD" or "glass") has an on-glass row-column driver chip for illuminating pixels but has
no on-glass frame buffer or memory. The pixel data must be delivered at approximately 60Hz per complete frame by the
MCU, and stored and managed in system DRAM.

The RX63N/631 MCU does not include an on-board graphics controller; however the raw horsepower of this MCU family,
when combined with its peripherals and Serious GatlingTM Technology on the SIM231 can deliver impressive user interfaces,
including multi-layer alpha blending, animation, and more.

With a 480x272 pixel resolution at 16 bits of color information per pixel (in RGB565 format), each frame requires 130,560
bytes of RAM. For a double-buffered system, 261,120 bytes for the two frame buffers are required. Serious Gatling
Technology delivers excellent performance in this mode: less than 17% of the SDRAM bandwidth is required to deliver the
frame buffer to the LCD at 60Hz.

For color-sensitive applications, such as those with extensive gradients, the SIM231 also supports 24 bit color mode. When
24-bit color mode is enabled, twice as much DRAM is required per frame buffer, and SDRAM bandwidth required to deliver
the frame buffer to the LCD at 60Hz is less than 33%.

                                  SIM231 Technical Reference Manual                                24

Some SIM231 variants include an integrated 4-wire resistive touch feature: a resistive film over the LCD returns an analog
voltage in two dimensions which can be read by the touch controller and translated with a ratio into a pixel hit position.
These touch-enabled variants also include a capacitive proximity detection feature where the proximity of a bare finger will
be detectable by sensors which can be read by software.

SERIOUS GATLINGTM TECHNOLOGY

Designed to assist the MCU's existing pixel to LCD connectivity, Serious GatlingTM Technology enables lower CPU overhead,
increased throughput, and improved efficiency of rapid-fire pixel delivery from the CPU-Memory subsystem to the LCD
display.

On the SIM231, the technology is implemented in an FPGA. The FPGA chip accommodates a fly-by-burst-mode DMA from
the MCU into its internal pixel FIFO and delivers a fixed rate pixel stream to the LCD. It also manages all the timing to the
LCD screen, delivering pixels at a rate determined by the FPGA configuration. This configuration (available from Serious) is
downloaded at boot time through the RX MCU's SPI port.

The DMA unit on the RX MCU must be programmed to continuously deliver the current frame buffer as requested by the
chip in a DREQ#/DACK# cycle using SDRAM continuous access single cycle mode.

               The no-cost Serious Human InterfaceTM Platform software automatically initializes the FPGA and includes the correct driver
               for the SIM231's implementation of Serious Gatling Technology.

ON-MODULE PERIPHERALS

The SIM231 contains numerous on-module peripherals many common to a vast and diverse set of OEM applications,
including a Real Time Clock/Calendar (RTCC) (battery-backed on some modules), USB device, USB host, serial FLASH, high
speed UART(s), EEPROM, bi-color indicator LED, and more.

ON-MODULE MEMORY

The SIM231 module has a variety of memory for storage of program, data, images, parameters, etc.:
        FLASH Memory:
          Up to 16MB serial FLASH memory attached via dedicated SPI (either 1 or 2 8MB chips)
        EEPROM
          Up to 4kbits EEPROM
        RAM
          128kB RAM within the RX63N/RX631 MCU
          Up to 16MBytes of SDRAM

COMMUNICATIONS AND CONNECTORS

The SIM231 has numerous off-module communication ports and connectors. Some may or may not be available on specific
SIM231 variants.

POWER

The SIM231 module can be powered from the +V_EXT signal (typically 5V) available on several connectors:
   16-pin Power/Communications Connector
   60-pin Expansion Connector
   SHIP Programming Port

The SIM231 can also be powered via the +5V_USBF signal on the USB device port. Commonly during GUI development
with SHIPTide the USB Micro B connector can be connected to an adequately powered USB port.

Alternatively, and especially for those variants without the USB Micro B connector, the SHIP Programming Port can supply
5V from a suitable USB port on a powered hub, PC port, or USB AC Adapter when used with a SHIP Programming Adapter
200 (SPA200) and the SHIP Programming Connector SPC200.

       The permissible input voltage range, by variant, is detailed in the DC Maximum Ratings section.

MCU BOOT MODES AND THE USB BOOT FLASH

Three separate FLASH memory areas are available inside the RX MCU: Program FLASH, Data FLASH, and USB Boot Mode

FLASH as well as one Boot Mode ROM. Three "boot modes" are available on the RX631/RX63N MCU family based on the

state of the MD and PC7 pins when the RESET# signal is released. Depending on which of the three boot modes is

determined at reset, the MCU jumps to a corresponding start address for code execution.

MD PC7 Boot Mode                       Execution start after RESET#

High X Normal Program Boot Mode        Program FLASH reset vector
Low Low ROM Boot Mode                  Start of Boot Mode ROM
Low High USB Boot Mode                 Start of USB Boot Mode FLASH

In normal Program boot mode, the PC7 signal is completely available for program and system use. However, in the two
special boot modes, PC7 must remain fixed throughout the operation of the mode until the subsequent RESET# and is not
available for general program and system use during these special modes.

The MD1 and PC7 signals are weakly pulled high on the SIM231, ensuring that for normal operation the MCU will boot in

Normal Program Boot Mode, starting execution at the main RX MCU Program FLASH reset vector. The Program FLASH can

                                    RELEASE
                            SIM231 Technical Reference Manual  27

be (re)programmed in a variety of ways, including the JTAG port exposed on the Tag-Connect JTAG Port and 60-pin
Expansion Connector.

               The Serious Human InterfaceTM Platform v5 can update the RX MCU program FLASH over many different connections
               including USB, SPI, and UART using the built-in Tug bootloader and the SHIP Bridge protocol. This update can be performed
               from within the SHIPTide development environment: no JTAG debugger or C programming tools are required.

Because the PC7 and MD1 signals are available on the Tag-Connect JTAG Port and 60-pin Expansion Connector, they can be
pulled low externally to the SIM forcing the SIM to go into one of the two special boot modes. Consult the Renesas
RX63N/RX631 MCU Hardware Manual for additional boot mode details.

In USB Boot Mode, the processor begins execution in the 16KB USB Boot FLASH rather than the normal program FLASH.
Serious programs the USB boot area with special firmware designed to function with the Serious Human InterfaceTM
Platform tools, enabling reprogramming of the SHIPEngine and Serial FLASH with new GUI cargo files. The algorithm in this
firmware is proprietary, and when the SIM231 boots in USB Boot mode the USB port will identify itself as requiring up to
500mA of bus power and having USB Vendor ID 0x25D8 (registered exclusively to Serious) and USB Product ID in the
0x0001 to 0x0099 range depending on the version of the protocol contained in the area.

FIRMWARE SHIPPED ON THE SIM231
The SIM231 comes with a pre-installed version of SHIPEngine v5.x, the runtime binary component of the Serious Human
InterfaceTM Platform (SHIP).

SHIPEngine v5.x includes a complete boot loader (Tug) which includes upgrade and communications capabilities using the
SHIP Bridge protocol. The boot loader and off-line upgrade system is installed in the top 8kB of the RX program FLASH as
well as in the primary serial FLASH. The SHIPEngine v5 is contained in the remainder of the RX program FLASH. The GUI
and configuration data, as in SHIP v4, is also contained in the remainder of the serial FLASH(s).

               To use the full features of the Serious Human InterfaceTM Platform, you need to preserve the Serious firmware in the RX
               program FLASH and serial FLASH(s). Modifying/erasing either the serial FLASH(s) or RX program FLASH will render the
               SHIPEngine and boot loader unusable. Restoring these images can be accomplished using USB Boot mode and
               SHIPTide/SHIPCrane tools available at www.seriousintegrated.com.

REPROGRAMMING THE SERIAL FLASH
The on-SIM serial FLASH chip(s) can be re-programmed via software or with custom hardware by externally holding the
SIM in RESET# and accessing the serial FLASH through the SPI bus present on these connectors:

   60-pin Expansion Connector
   SHIP Programming Port

               The Serious Human InterfaceTM Platform v5 can update the serial FLASH(s) over many different connections including USB,
               SPI, and UART.

REPROGRAMMING THE RX MCU PROGRAM FLASH

The RX MCU program FLASH can be re-programmed from a JTAG debuggger (such as the Renesas E1 or Segger L-Link) via
the Tag-Connect JTAG Port using a Tag Connect TC2070 cable, available directly from Tag-Connect.com or Digi-Key.

               The Serious Human InterfaceTM Platform v5 can update the RX MCU program FLASH over many different connections
               including USB, SPI, and UART.

LCD DISPLAY

The LCD display (or "glass") on the SIM231 is a 4.3" diagonal active area 480x272 TFT with optional 4-wire resistive touch
layer. The LCD display has no on-glass frame buffer or memory. The MCU, with the Serious Gatling Technology assistance,
is responsible for delivering pixel data at a specific frequency to the LCD display as well as various clock signals otherwise
the display will not function correctly and will not display a stable image. No valid image is possible unless the MCU is
operating and, under software control, the MCU is delivering pixel and timing data to the LCD display continuously. The
LCD display, in absence of a valid signal from the MCU, may automatically enter self-test mode and display various cycling
test patterns.

The LCD backlight is enabled when P24/MTIOC4A-BLEN is driven high, which turns on the backlight power boost circuit
driving a constant current to flow through the backlight LEDs on the LCD. This enable signal has a weak pull-down, so the
backlight is off until the MCU pin is initialized, including during and directly after system RESET#. This MCU pin is hardware
pulse-width-modulation (PWM)-capable to enable 0-100% backlight dimming based on the duty cycle. A typical 1kHz
PWM clock with 16 steps for a net frequency of 64 Hz is generally sufficient and flicker free with duty cycles from 0 to 100%.
The PWM clock should not exceed 16kHz.

The Serious Human InterfaceTM Platform has the backlight driver included; setting the platform glass backlight value to 0 to
100% automatically modulates the dimming circuit.

GRAPHICS CONTROLLER
Since the LCD display has no on-glass frame buffer, pixel data must be held in memory and streamed continuously to the
display hardware. This memory must also be MCU accessible in order for software to "draw" into the frame buffers and
transfer images and drawings to the screen.

On the SIM231, the RX63N/631 has insufficient internal RAM to contain frame buffers: multiple frame buffers can be
created in the external SDRAM. Typically, two frame buffers are used: one as the currently displaying frame, the other as a
hidden frame where updates and drawing can happen. Then the two can be swapped (the display controller DMA channel
pointed at the hidden buffer) to expose the new frame and allow the prior-displayed frame to be used as the new working
buffer.

The RX63N/631 is a high performance general purpose MCU capable of driving an LCD display with very little external
logic. The SIM231 implements Serious GatlingTM Technology: a combination of MCU-supported burst DMA and SDRAM with
external logic delivering rapid-fire pixels to the LCD display with minimal MCU overhead. Depending on the configuration
of the technology and the associated driver, the LCD can be operated in 16 bit or 24 bit color modes.

               The no-cost SHIPWare software at mySerious.com includes all initialization code, drivers, and utilities to enable the basic
               functions of the graphics controller, including portrait and landscape modes and adjustable frame rates. This software is
               available after account sign-up and registration of your SIM231 serial number.
               The Serious Human InterfaceTM Platform software system has fully-integrated and optimized drivers and frame buffer
               management, making the graphics controller details transparent to the GUI designer.

TOUCH CONTROLLER
Some SIM231 family members include a resistive touch layer bonded to the LCD display. The layer can return an analog
voltage in two dimensions to be read by analog-to-digital converters in the touch controller and translated with a software
algorithm into a pixel hit position.

Resistive touch layers are made from a highly resilient Polyethylene Terephthalate (PET) film, and have the advantage of

being robust and usable with a stylus, finger, or any blunt object. Unlike typical capacitive touch screens, resistive touch

screens do not require the bare finger and can be used through gloves important for certain medical, industrial, and

automotive applications. They also work well in wet conditions, although appropriate caution must be taken to ensure
liquids do not flow onto the SIM231 or other circuitry. Serious application note AN0201: Resistive Touch Bezel Guidelines is
a good resource for understanding how to mount a touch screen behind a bezel.

Some chemicals including (but not limited to) Ketone-based products, harsh cleansers, and abrasive cleaning products can
discolor and/or damage the PET film. To ensure long usable lifetime, make sure end-users are well-informed on how to
clean and maintain the touch screen.

The SIM231 employs a stand-alone 4-wire resistive Semtech SX8656 touch controller with proximity sensing. The SX8656
provides sophisticated touch sensing/processing and delivers touch data back to the MCU via I2C. When touch data is
available (for example, when the screen is pressed or a finger is dragged along the touch panel), the touch controller
generates an interrupt on an MCU interrupt pin at which point software can read the device and determine the pixel
coordinates and/or action.

See the I2C Device Summary for the complete table of I2C device addresses.

See the Interrupt Summary for the complete table of external peripheral interrupts.

The no-cost SHIPWare software at mySerious.com includes a full source-code implementation of a touch driver for the
SIM231.
The Serious Human InterfaceTM Platform has integrated touch drivers and algorithms that automatically map touch
coordinates to GUI objects.

PROXIMITY SENSING

Most standard touch-enabled SIM231 variants include the SX8656 with proximity sensing capabilities which senses the
presence of objects (like a bare finger) that alter a projected capacitive field above the touch screen surface. This enables,
for example, software to "automatically" brighten the LCD backlight when a finger approaches the screen. Only a general
"near" or "not-near" indication is available from this capability, and if the end user is wearing gloves or in a wet
environment this feature may not function consistently an inherent challenge with capacitive detection systems.

               The Serious Human InterfaceTM Platform has integrated proximity drivers and algorithms that can deliver "near" and "not-
               near" events to your GUI.

AMBIENT LIGHT SENSING

Some variants of the SIM231 include an Ambient Light Sensor ("ALS"), the Avago APDS-9002-021 or similar device
designed to help determine low ambient light situations. Since the backlight on the SIM231's LCD display can be very
bright, especially in these low light situations, software may want to modulate the backlight brightness to improve
readability as well as backlight LED longevity. The ALS is connected to MCU analog input P46/AN006-ALS and the ambient
light intensity can be derived from the ADC value.

               The Serious Human InterfaceTM Platform has integrated ambient light sensor drivers and algorithms that can deliver a 0 to
               100% reading and change-events to your GUI.

POWER SUPPLIES

POWER INPUT: +VIN_MAIN

The SIM231 is powered internally from the +VIN_MAIN signal. This signal pulls power from the higher of the two
connected inputs +VEXT (external voltage) and +5V_USBF (USB device input voltage):

Since the input voltage can have a fairly wide range, as low as 3.6V and as high as 5.5V depending on the variant, there are
several switching power supplies attached to +VIN_MAIN to generate voltages required on the SIM231:

                            Signal Name  Voltage   Circuits Powered
                            +3V3           3.3 V

                            BL_LED+/-     ~19.2 V
                                                    USB Host A Connector
                                                    Piezo Voltage Booster
                                                    LED Constant Current Backlight

POWER INPUT: +VEXT

The main power supply for the SIM231 is generally applied to the +VEXT signal available on the following connectors:

Power Signal                Description            Connectors Where Present
+VEXT                       External Power
                                                    16-pin Power/Communications Connector
                                                    60-pin Expansion Connector
                                                    SHIP Programming Port

There is no support for simultaneous power connectivity or dynamic power source switching between these connectors.
See the DC Characteristics for +VEXT limits.

Connecting more than one power source to the SIM +VEXT signals simultaneously may damage your SIM or even
connected equipment. Only one connector should drive the +VEXT signal. The remaining connectors can, within the
limits of the SIM, receive power from this signal.

TURNING SIM231 OFF: PWRDWN#
All regulators on the SIM231 can be turned off via the PWRDWN# signal, available on the following connectors:

   16-pin Power/Communications Connector
   60-pin Expansion Connector

PWRDWN# is weakly pulled high on the SIM to deliver the default powered-on behavior. Driving this signal to GND via logic
(or connecting it to GND via a simple SPST switch) puts the SIM in power down mode. The USB host, and LCD backlight are
also powered off, so when PWRDWN# is asserted the SIM can consume only a few mA.

+3.3V (+3V3) REGULATION

The +VEXT main power rail is converted to 3.3 V (the +3V3 signal) through the ISL9104 or equivalent switching regulator.
This regulator is capable of 90%+ efficiency at up to 500mA.

The 3.3V supply (+3V3) is used throughout the module, powering most of the logic and peripherals. It is also delivered to
the 60-pin Expansion Connector and the 16-pin Power/Communication Connector, but is only meant to supply a small
amount of power to an attached system. The amount of 3.3V power available to these connectors is limited by (a) the total
capacity of the regulator and (b) the excess power available on the +3V3 signal after calculating the incoming available
power minus that used on the SIM231. The DC Power Characteristics information in this manual can assist in this
calculation: the actual amount available is highly dependent on the specific features used on the specific variant selected
by the system designer.

+5V_USBF:USB DEVICE ("FUNCTION") POWER

The external USB device supply is merged with the +VEXT input via the two forward diodes as described above. The
+5V_USBF signal is present on the following connectors:

   60-pin Expansion Connector
   USB Micro B Device Connector
   SHIP Programming Port

When driving the +5V_USBF input from one of these connectors, it is wise to ensure the +VEXT is at or above the nominal
5V of the USB input to ensure the +VEXT supply is bearing the primary power needs of the SIM.

                The USB Micro B power (+5V_USBF) signal on all these connectors is directly connected together: simultaneous
                connection may damage the SIM or connected devices such as a PC or USB Hub.

The SIM231 may be powered from the +5V_USBF signal as long as the USB hub or PC port can supply sufficient power to
the module, and the features used on the module are used within this power envelope.

+5V_USBH: USB HOST POWER

Some variants include a USB Embedded Host Port with USB A connector. This USB port can supply power to some USB
devices, such as keyboards, mice, and thumb drives. A TI TPS2501 USB Host Power Boost Controller or equivalent ensures
that even if +VEXT is below 4.75V, the USB Host A connector is still powered with 5.0V as required by the USB standard.

This supply is enabled when the MCU GPIO P16/USBH_VBUSEN is asserted high. P16/USBH_VBUSEN is weakly pulled low
so during RESET# the USB host power supply is disabled. Similarly, during PWRDWN#, this power supply is also disabled.

Up to 150 mA is delivered to the USB Host connector. This 150 mA will be sufficient for all self-powered devices (those
devices that have their own, independent power supplies), as well as some bus-powered devices such as USB thumb
drives. However, it will not be sufficient for higher bus-powered devices such as USB powered printers and hard drives
without their own separate power supplies. The boost controller circuit also provides overcurrent shutoff and controller
notification to the P14/USBH_OVRCURA MCU port if the device plugged into the connector draws more than 150mA.

The USB Host power supply and any connected device can be a significant power load on the system. When initially turned

on there is an inherent short term power drain as the booster is enabled and the +5V_USBH power is generated and

stabilized. If +VEXT is too low, the impedance of the external power supply too high, and/or the transient current support of

the supply insufficient, then the SIM can reset. Observe the minimum recommended +VEXT DC Maximum Ratings carefully

when the USB host feature is used.

LCD PANEL BACKLIGHT POWER: P11-BLEN AND BL_LED+/BL_LED-

The LCD Panel has an array of LEDs creating the backlight. These LEDs require a constant current source of approximately
25mA, created and managed by an LED driver chip such as the Diodes Inc. AP5724 or On Semi CAT4149 or similar device
and delivered to the LCD LEDs on signals BL_LED+ and BL_LED-. The voltage on this output can vary, but is typically 19.2V
depending on the specific LEDs used in the LCD glass.

The backlight driver is always disabled during RESET# and PWRDWN#. The backlight driver is enabled when MCU signal
P11-BLEN is driven high.

Backlight power is a significant portion of the SIM's power consumption. Software should carefully manage the backlight
to be powered on as infrequently and for as short a time as possible especially in battery powered systems, but also to
ensure backlight longevity. Reducing the backlight power can significantly extend backlight lifetimes. Typically, operating
the backlight at 50% brightness can more than double the backlight lifetime.

Software algorithms can PWM this pin to enable backlight dimming. A PWM driven by a typical 1 KHz clock with 16 PWM
steps for a PWM net frequency of 64 Hz is generally sufficient and flicker free with duty cycles from 0 to 100%. In no
circumstances should the PWM clock exceed 16 KHz.

The proximity and ambient light sensing features (where available) can be used to assist in extending backlight longevity by
dynamically adjusting the backlight power through software.

The display backlight is a significant power load on the system. When turned on there is an inherent short term power surge
as well an overall power demand increase. If +VEXT is too low, the impedance of the external power supply too high, and/or
the transient current support of the supply insufficient, then the SIM may intermittently reset. Observe the minimum
recommended +VEXT DC Maximum Ratings carefully.

The Serious Human InterfaceTM Platform has the backlight driver included; setting the platform glass backlight value to 0 to
100% automatically modulates the dimming circuit.

BATTTERY BACKED REAL TIME CLOCK/CALENDAR (RTCC): +VBAT

Some SIM231 variants have an external I2C-connected battery-backed Real Time Clock/Calendar chip.
On these variants, there may also be a coin cell battery holder that, when populated, can keep the
clock/calendar running even during +VEXT power outages and through RESET# and PWRDWN# states.

The battery backup is provided from a common CR1025-type 3V battery inserted into a simple battery
holder on the SIM. This is not designed to be a rechargeable battery, nor does any circuit on the SIM231 supply power to
charge this battery. The only purpose and connection of this coin cell battery is to provide the backup power signal +VBAT
to the RTCC chip to keep the clock/calendar running in the event that all other power sources are removed. This battery
can keep the clock keeping time for up to several years without replacement. The RTCC automatically switches to use the
coin cell power only when main power is not available, so in a system that normally has main power applied the coin cell
battery is rarely used. See External RTCC for more information.

MEMORY

SERIAL FLASH
All SIM231 family members include one or two SST SST25VF064C serial FLASH devices. The SST25VF064C is an 8 megabyte
device with 2048 4KByte erasable blocks as well as a built-in 64-bit unique serial ID and 192 bits of OTP ID space.

See the SST25VF064C data sheet for hardware specifications and programming details and the Renesas RX63N/631
datasheet for information on the SPI master port configuration.

These devices are connected to RSPCKA SPI channel of the MCU:

Note these two reset lines are not asserted in module RESET# mode and have weak pull-ups. Both parts have internal
power-on-reset circuits and, if desired, software on the MCU can explicitly reset the parts with the P23-SFLASH0_RESET#
and P25-SFLASH1_RESET# signals. Both FLASH devices can be reprogramed under software control.

SFLASH0 can be reprogrammed from the 60-pin Expansion Connector and/or PCB Edge Connector directly using external
hardware (for example with the SHIP Programming Adapter 200 (SPA200)) by holding the module in RESET# and
exercising the control lines PC4-SFLASH0_CS#, PC6/MOSIA, PC7/MISOA, and PC5/RSPCKA.

SFLASH1 can be reprogrammed from the 60-pin Expansion Connector directly using external hardware by holding the
module in RESET# and exercising the control lines PC0-SFLASH1_CS#, PC6/MOSIA, PC7/MISOA, and PC5/RSPCKA.

SFLASH1 can be also be "overridden" on a daughter card plugged into the 60-pin Expansion Connector. Asserting P25-
SFLASH1_RESET# from a daughter card will render any serial FLASH #1 on the SIM unresponsive to the MCU. Using the
PC0-SFLASH1_CS#, PC6/MOSIA, PC7/MISOA, and PC5/RSPCKA signals to drive an on-daughter-card external serial FLASH
device will cause this external FLASH to respond to the MCU as if it were the serial FLASH #1.

Serial FLASH#0 contains factory-programmed information including the serial number of the unit as well as variant/version
information.

Do not write to serial FLASH#0's SST25VF064C's OTP region.
This region is reserved for manufacturing and configuration information by Serious.
Modifying or writing to this area will void your warranty with Serious and render the module unusable.

To use the full features of the Serious Human InterfaceTM Platform, you need to preserve the Serious firmware in the serial
FLASH(s). Modifying/erasing either the serial FLASH(s) or RX program FLASH will render the SHIPEngine and boot loader
unusable. Restoring these images can be accomplished using USB Boot mode and SHIPTide/SHIPCrane tools available at

SDRAM
The SIM231, depending on the variant, includes an 8 or 16MB SDRAM with a 16-bit data bus configuration. The SDRAM is
designed to operate at 48 MHz with a 96MHz MCU core frequency. The MCU's built-in SDRAM controller can be configured
to enable this memory in random access or burst modes.

The SHIPWare source code has SDRAM initialization routines you can examine and use with the SIM231. SHIPWare is
available at no cost for registered hardware users on mySerious.com.

SHIPEngine (the runtime engine of the Serious Human InterfaceTM Platform) automatically configures and manages the
SDRAM

Serious makes every attempt to maintain compatibility throughout the availibility lifetime of our devices. However
components especially memory are subject to ongoing and sometimes frequent process, density, and availability
changes. SDRAM sizes for each variant are a minimum specification and vendors may vary. Software must be written to
comprehend sizes beyond this minimum specification and various vendors and Serious reserves the right to substitute at any
time larger devices than the specfied variant minimum.

EEPROM
The SIM231 features an Atmel ATSHA204 Cryptographic/Authentication device. Within this device is 4k bits (512 bytes) of
EEPROM for storing security keys and/or parameter data. If the cryptographic and authentication features of the ATSHA204
are not used, the device can be used simply as a user EEPROM.

               Do not write to the ATSHA204's one-time-programmable (OTP) region.
               The ATSHA204 has 4.5kb total EEPROM, 512 bits of which are an OTP area reserved by Serious.
               Tampering with this OTP area will void your warranty with Serious and render the module unusable.

The ATSHA204 is an I2C device on the SIM's main I2C control bus. This bus is shared by numerous devices: see the I2C
Device Summary for more information including I2C addresses. Consult the Atmel ATSHA204 Data Sheet for programming
and hardware information of the ATSHA204 device.

SERIOUS SERIAL NUMBER
Beyond the 8 or 16MBytes of data area, the SST25VF064C device(s) also contain a 256 bit (32 byte) one-time programmable
(OTP) region.

Serial FLASH #0 contains factory-programmed information including the serial number of the unit as well as variant/version
information. Reading this information at run-time can enable software to dynamically adapt to the specific variant as well
as accommodate any software-visible differences between versions of the specific module.

CRYPTOGRAPHIC/AUTHENTICATION DEVICE

The SIM231 features an Atmel ATSHA204 Cryptographic/Authentication device with built-in Random Number Generator
(RNG) and EEPROM. The ATSHA204 is an I2C device on the SIM's main I2C control bus. Within this device is 4kbit (512 byte)
EEPROM for storing security keys and/or parameter data. If the cryptographic and authentication features of the ATSHA204
are not used, the device can be used simply as a user EEPROM.

The 512 bit OTP area within the 4.5Kb EEPROM is pre-programmed by Serious and is unavailable for other uses.
Modifying or writing to this area will void your warranty with Serious and render the module unusable.

See the I2C Device Summary for the complete table of I2C device addresses.

The Serious Human InterfaceTM Platform's firmware (SHIPEngine) uses this device to ensure it is running on authorized Serious
hardware platforms.

Consult the Atmel ATSHA204 Data Sheet for programming and hardware information of the ATSHA204 device.

CLOCKS, OSCILLATORS, AND TIME KEEPING
The following terms are important to understand theory of operation described herein:

Clock:       A square-wave logic-level periodic signal (not a clock as in a timekeeping clock of time/date/minutes/hours,
Oscillator:  etc.)
RTCC:        A crystal or resonating oscillator circuit that creates a fixed-frequency sine wave used in a specific circuit to
             create a clock signal
             A real time clock/calendar which keeps track of the correct time/date as set by the end user or some other
             means.

There are many producers and consumers of stable clock signals (or "clocks") on the SIM231:

1) The RX MCU is typically driven with a 12 MHz clock signal, which is internally in the MCU multiplied by 8 for a
    96MHz CPU clock speed.

2) Some variants have a 32.768 kHz crystal attached to an external RTCC chip or to the MCU directly.
3) The USB Device port and USB Host port require a 12MHz clock to operate within USB specifications.

HIGH SPEED (12 MHZ) CLOCK

The SIM231 RX MCU's high speed clock system is driven by a single 12MHz clock oscillator. In this configuration, the CPU
core frequency must be derived from this 12MHz source typically yielding 96MHz in the x8 PLL mode. USB device and
host peripherals are therefore appropriately supplied with 12MHz clocks and the SDRAM bus runs at 48MHz.

MCU REAL-TIME CLOCK/CALENDAR (RTCC)
The RX MCU has an internal Real-Time Clock/Calendar (RTCC) peripheral, designed to be driven from an attached 32.768
KHz crystal or external 32.768 KHz clock source.

Some SIM231 variants have an external RTCC chip. This chip, when properly programmed, delivers a clean 32.768 kHz
square wave on its CLKO pin to the MCU's RTCC external clock input XCIN. Other variants have a simple 32.768 KHz crystal
connected to the RX MCU's XCIN/XCOUT crystal pins. Some variants have no external crystal or clock input for the RTCC.
Consult the variant chart for more information. The RX must be configured (via software and registers) to be enabled and
use the correct RTC clock input mode.

               The variant can be determined at runtime by reading the variant information from the serial FLASH.

On variants with the external RTCC chip there may also be a battery backup capability where the clock continues to run
and keep time, even when external power is lost or the module is put in PWRDWN# or RESET# modes.

The MCU's RTCC, however, is not battery-backed: when system power is lost from the SIM231 (or the PWRDWN# signal is
asserted) the MCU's RTCC stops operation and timekeeping is lost. The MCU's RTCC must be re-loaded after every time
power is restored to the SIM. In many system architectures, the time/date is available in another portion of the system, and
over a communications link the remote time/date can be periodically retrieved and programmed in to the MCU's RTCC
registers.

EXTERNAL RTCC WITH OPTIONAL BATTERY BACKUP

Some SIM231 variants have an external NXP PCF8523 RTCC chip. This RTCC is completely independent of the RX MCU's
RTCC, and some variants support a CR1025 backup lithium coin cell battery such that when main power is lost to the SIM,

the coin cell ensures the external RTCC continues to run and keep time. With a high quality battery, the clock/calendar
could run for up to several years without replacement.

The NXP PCF8523 RTCC, if present, has a dedicated 32.768 KHz crystal. The RTCC's CLKO pin is connected to the MCU's

RTCC clock input XCIN, and must be configured to output a 32.768 KHz input if the MCU's RTCC operation is required.

               See the I2C Device Summary for the complete table of I2C device addresses.

Consult the PCF8523 datasheet for more hardware specifications and programming information.

AUDIO

Depending on the variant the SIM231 supports various audio options including:
   piezoelectric sounder for alarm and notification "beeps"
   the 10-bit Single Channel DAC used as a waveform output

          SHIPEngine has built-in audio support. With only a few lines of code you can, for instance, deliver an ADPCM .wav file to the
          DAC output or make the piezo sounder beep at a given frequency/volume.

          Vendors such as Micrim and Segger provide software solutions that can deliver audio waveforms to the audio outputs.
          Renesas also has example code for this feature.

PIEZO SOUNDER
Some SIM231 variants include a piezoelectric sounder suitable for notifications, alarms, etc.

The sounder is activated by applying a frequency to the P86-BUZZ signal. The MCU can hardware-PWM this signal so
software will typically be written to drive the sounder at a given frequency with 50% duty cycle for full volume output. The
duty cycle can be reduced to lower the volume.

The sounder's resonant frequency is centered between 2400 and 4000 Hz. Waveforms in this frequency range will generate
the loudest perceived sounds.

The voltage multipliers within the Piezo driver are controlled with two MCU GPIO pins, P05-BZEN1 and P07-BZEN2 as

follows:

                                         P05-   P07-        Voltage   Volume

10-BIT SINGLE CHANNEL DAC

All SIM231 variants expose the P03/DAC0 signal from the RX MCU to various connectors. The RX MCU has a built-in 10-bit
DAC which can be driven at a software-configured frequency using the MCU's data transfer controller (DTC) or DMA. This
3.3Vp-p output can be used to drive speech-quality audio (via an off-module amplifier/speaker) or used for any other
purpose requiring an analog output.

SHIPEngine has built-in audio support using this DAC. With only a few lines of code you can, for instance, deliver an ADPCM
.wav file to the DAC output or make the piezo sounder beep at a given frequency/volume.

USER LED

Some SIM231 variants have a bi-color (red/green) LED located on front of the display-side of the module. A bi-color LED is
actually two independent LEDs in one package: the LED on the SIM231 has red and green LEDs that, when both are on,
have an amber hue. Typically, a plastic or metal front panel enclosure will expose this LED through a plastic light pipe; for
example, the BiVar PLP1-125-F. There is no requirement for an end-system to expose this LED. The enclosure may cover it
completely and render it un-viewable if desired.

CONNECTORS

SHIP PROGRAMMING PORT
Programming the SIM231's GUI and SHIPEngine from the SHIPTide development tools is typically
accomplished by connecting the PC running SHIPTide to the SIM using the USB Micro B connector
on the SIM. The SHIP Bridge protocol within the SHIPEngine firmware as well as the Tug Boot Loader
can operate over this USB link.

In some variants, the SIM231 will not have the USB Micro B Device Connector populated and some
customer designed enclosures incorporating a SIM system may obstruct access to the USB Micro B
Device Connector.

In these cases, the SHIP Programming Port on the SIM231 can be used to expose the USB device port when used with a
SHIP Programming Connector SPC200 and SHIP Programming Adapter 200 (SPA200). This port replaces the PCB Edge
Connector used on prior SIMs and offers many new features, including:

   Fast connect/disconnect
   Robust up to 1,000,000 insertion cycles for the SPC200 cable-end
   More features direct reprogramming capabilities of the Serial FLASH
   Supports USB 2.0 480mbps High Speed for SIMs with that capability (e.g. SIM535)
   Small footprint
   Polarized to prevent connection if the connector is reversed

This new SHIP Programming Port is available and identical on the SIM115, SIM231, and SIM535.

In the case that a daughter card obstructs access to the SHIP Programming Port, this port may be mirrored up on the
daughter card all the signals are available on the 60-pin Expansion Connector. Contact Serious for details.

SHIP PROGRAMMING CONNECTOR SPC200

Into the SHIP Programming Port is plugged a small connector the SHIP Programming Connector 200, or SPC200.

This small connector is polarized plugging it backwards into the SHIP Programming Port
does not connect the pins to the SIM.

The SPC delivers the SHIP Programming Port signals to a small cable-friendly connector on
one side. It leverages off-the-shelf HDMI cable/connector technology for this purpose,
though the signals and power transmitted through the cable are not compatible with the
HDMI standard.

               Do not plug this cable into a normal HDMI port, for example on a laptop, DVD player, or TV.
               The connector was chosen to leverage off-the-shelf cabling, but is not wired to the HDMI standard.
               Connecting the SPC200/SPA200 with to any other device may damage the device or your SIM/SPA permanently.

Use a short, high quality HDMI v1.4 cable with a "Type D Micro" connector to plug into the SPC200. The other end of the
cable should be the larger, more common "Type A" cable which plugs into the SHIP Programming Adapter 200 (SPA200).

SHIP PROGRAMMING ADAPTER 200 (SPA200)
The Serious Programming Adapter SPA200 is an inexpensive programming/USB intelligent adapter for use with the SIM231
and other Serious Integrated Modules. The SPA200 includes the following connectors:

      USB Micro B for a PC to talk to both the SPA and the downstream USB device port of the SIM
      Barrel Jack for powering the SPA and SIM from a USB AC power adapter
      HDMI Type A connector for connection to the SPC200`s type D micro-HDMI type D connector via a standard cable

At its very simplest, the SPA200 enables connectivity between a PC USB port and the SIM's USB device circuitry, even if the
SIMs USB Micro B connector is not populated or is obstructed. This is necessary for development and volume
reprogramming/updating of the GUI and firmware from the SHIP environment.

The SPA200 has numerous other features beyond the scope of this document; contact Serious for more information or visit
www.seriousintegrated.com/SPA200.

TAG-CONNECT JTAG PORT

Tag-Connect is a rapid-connection system designed for in-situ reprogramming or connectivity. It adds
no cost to the target hardware and is implemented on the PCB through a simple set of landing pads
and guide holes. The SIM231 has a 14 pin pad-set designed to accommodate the TC2070-IDC-NL and
associated TC-FRICTION retaining clip. The port is designed such that the IDC (header) connector on
the TC2070 ribbon cable can plug directly into a Renesas E1 or Segger J-Link RX
programmer/debugger without any additional adapters or cables.

Plugging into incompatible devices may damage the SIM or connected device.

16-PIN POWER/COMMUNICATIONS CONNECTOR
A common way a SIM231 is connected to another system is via the JST ZPD Series wire-to-board
connector. Relevant part numbers are:

JST Part Number             Description

BM16B-ZPDSS-TF(LF)(SN)      Shrouded Header, SMT, 16 position (2x8), Vertical
ZPDR-16V-S                  Wire Housing
SZPD-002T-P0.3              Crimp pin for AWG#24 to 28 stranded wire (see below)

This connector is identical to that found on all upcoming Serious modules, including the SIM115, SIM231
and SIM535. Older SIMS had the 7 position JST GH series (SM07B-GHS-TB), and customer feedback indicated that more
signals were desired, including PWRDN# and the SPI port for higher speed communications. In addition, higher power
handling capability was need for larger modules including the SIM535. The JST ZPD series is fully RoHS and UL94V-0
compliant. In addition, it supports full -40 to 85C operation.

               While operational to -40C, take care with insertion/removal at low temperature; the housing will be more susceptible to
               breakage.
               The JST ZPD series data sheet indicates a minimum operational temperature of -25C. JST has provided Serious a quality and
               reliability certification for this connector down to -40C. Contact Serious for a copy of this certification.

               Ensure sufficient wire size for the SIM to avoid wire overheating and adequate power handling capability.

               Several signals on this connector are directly connected to signals on other connectors, including +3V3, RESET#, +VEXT.
               Ensure these connections are appropriate or you may damage your SIM or connected equipment.

SHIPEngine v5 can use the UART or SPI on this connector with Modbus or the SHIP Bridge protocol to communicate
between the GUI and the attached system.

While the signal wires of the connector can be any size between AWG#24 and AWG#28, the two
main power connections (+VEXT, GND) should be sized according to the worst-case power
requirements of the SIM, taking into account the anticipated maximum actual operating
temperature. AWG#24 stranded high quality wire is recommended for the +VIN and GND power
connections, and generally AWG#28 is acceptable for the remaining signals.

JST America offers a sample service for wire harnesses, and custom wire harness manufacturers such as TLC Electronics can
assist in small to large volume harness development and production at reasonable cost.

SIM231 development kit versions, such as the SIM231-A01-DEV-01, include a sample single-ended wire harness for your
use in prototyping.

over-USB communications to a PC. Alternatively, a common RS232 chip (like the venerable MAX232 or similar device) can
boost the 3.3V UART levels to traditional RS232 voltages.

               Some Serious Communcations Modules (SCMs), for example the Serious Communications Module 117 (SCM117) include
               RS232, RS485, CAN transceivers and more, and dock into the back of the SIM231 directly.

USB MICRO B DEVICE CONNECTOR

All SIM231 variants have the USB device (or "function" in USB nomenclature) circuitry populated and
connected to the MCU's USB port. However, only some SIM231 variants have the USB Micro B connector
present. The electrical signals are always present on the following connectors (when present):

      60-pin Expansion Connector
      USB Micro B Device Connector
      SHIP Programming Port

The USB port is a USB 2.0 Full Speed (12 mbps max) port. The USB Vendor ID (VID) and Product ID (PID)
are software dependent. See www.seriousintegrated.com/docs/usb for information on Serious VID/PID
combinations.

The USB Micro B Power input pin (+5V_USBF) on various other connectors is directly connected to the USB Micro B power
input: connecting any of these simultaneously may damage your SIM or even connected equipment such as a PC or USB
Hub.

SHIPTide and SHIPEngine communicate over the USB Device port to download and update the SHIPEngine and GUI cargo
during the development and manufacturing processes.

USB A HOST CONNECTOR
Some SIM231 variants include USB 2.0 Full Speed embedded host circuitry along with the associated USB
"A" Connector. See USB Embedded Host Port for details on the port functionality and USB Host Power for
power enabling and limitations.

60-PIN EXPANSION CONNECTOR
While the 16-pin Power/Communications Connector is a common way to connect an external system to the SIM231, the
SIM's 60-pin Expansion Connector is the most flexible off-module connector available and exposes many more signals.
Often a simple 2-layer PCB daughter-card will be attached to the SIM231 using this connector to adapt the SIM231 to a
particular system environment.

The 60-pin Expansion Connector (when present) is the FCI 10106813-061112LF, a 60-position, 0.5mm, gold plated,
hermaphroditic board-to-board SMT connector. This connector is inexpensive, reliable, and widely carried at authorized
distributors, including Digi-Key and Arrow Electronics.

               Ensure you follow the recommended mechanical guidelines for custom daughter cards.

This connector exposes numerous serial, power, and GPIO signals, including the same connections as the 16-pin
Power/Communications Connector. If desired, this connector can be the only external connection to the SIM231.

            SHIPEngine v5 can use the UART, SPI, or USB signals on this connector as the main communications mechanism
            for communicating with external systems.

              The RX63N/RX631 MCUs have extensive I/O multiplexers allowing one of many different peripheral functions to map to a
              given I/O pin: consult the RX63N/RX631 hardware manuals for the complete list of options.

              Several signals on this connector are directly connected to signals on other connectors, including +3V3, RESET#, +VEXT.
              Ensure that common signal connections are appropriate or you may damage your SIM or connected equipment.

               Note the "mirrored" nature of the pin numbering, consistent with FCI Datasheet practices. For example, the above
               "daughter card perspective" diagram shows pins 1 and 2 as GND and SIM-VEXT respectively, whereas the SIM connection
               diagram above shows pins 1 and 2 as +VEXT and GND respectively mirrored.
               A complete package, including STEP 3D model as well as an Altium Designer project with board mechanicals, connector
               positioning, and connector library component are available from Serious to help you design your own daughter card.
               Contact Serious for more information.

UNIVERSIAL SERIAL BUS (USB)
Most SIM231 variants have USB 2.0 Full Speed (12Mbit/s) device (or "function") capability, though not all variants with the
capability also have the associated USB Micro B Device Connector. The USB Device signals may also be available on other
connectors on the SIM.

Some SIM231 variants also have a USB 2.0 Full Speed embedded host circuitry and associated "A" connector for support of
USB thumb drives, keyboards, mice, etc. The RX MCU USB Host signals, if the circuitry is implemented on the variant, are
also available on the 60-pin Expansion Connector. This feature enables daughter-cards to expose the USB Host
functionality in a physically different location than the SIM, and should only be used to relocate the connector on SIM
variants that already have the USB host capability.

DEVICE IDS
USB devices are uniquely identified by a Vendor ID ("VID") and Product ID ("PID"). VIDs are assigned under license by the
USB Implementers Forum. The Serious VID is 0x25D8.

               You may use the Serious VID only with the Serious Human InterfaceTM Platform by using SHIPEngine on the module. If
               you wish to program your own software for the SIM, you must obtain your own VID from the USB Implementers Forum.
               SIM231 comes with the Renesas USB boot mode loader installed, however the USB ID has been modified. The boot loader,
               when entering boot loader mode, will identify all SIMs (all families) with VID 0x25D8 and PIDs in the 0x0001...0x00FF range.
               This boot loader is available for re-installation; see Additional Information.

                            SIM231 Technical Reference Manual  45

USB SOFTWARE
Renesas provides extensive documentation of the RX MCU as well as example software: consult the Renesas USB Driver
software website.

             Vendors such as Micrim and Segger provide complete USB stacks pre-ported to RX63N/631 MCUs.

USB2.0 FULL-SPEED DEVICE PORT
The RX MCU used on the SIM has a USB 2.0 Full Speed 12mbps device (or "function") port. Most variants have the USB
device port circuitry connected to this port. From a data-connectivity perspective, this port is commonly plugged into a PC
and, depending on user-supplied software, can act like any number of PC peripherals such as a serial port.

               SHIPEngine contains built-in USB device stacks and protocols that allow the SIM to communicate directly with SHIPTide (the
               rapid GUI development IDE) so GUIs can be downloaded quickly and simply from the PC to the SIM.

While most variants have the USB Device capability, only a subset of these variants has the USB Micro B connector
populated. For those with the capability, it is accessible on the following connectors (if present):

      60-pin Expansion Connector
      USB Micro B Device Connector
      SHIP Programming Port

The SHIP Programming Connector SPC200 via the SHIP Programming Adapter 200 (SPA200) can connect into the SHIP
Programming Port on systems where the USB Micro B connector is not populated or is obstructed.

USB2.0 FULL SPEED EMBEDDED HOST PORT

Some SIM231 variants include a USB2.0 Full Speed 12mbps Embedded Host port powered by the RX MCU. This port can
(with the appropriate user-supplied software) drive a USB device such as a printer, Wi-Fi module, keyboard, or FLASH
thumb drive.

This port can supply up to 150mA of power and has built-in current limiting and over-stress shutdown capabilities. The
USB Host power supply system is described here. The USB host power is powered off during system RESET# and PWRDWN#
and must be enabled through software (the P16/USBH_VBUSEN signal on the RX MCU). An overcurrent situation will be
indicated on the P14/USBH_OVRCURA signal.
