MAX1464 Evaluation Kit
General Description
The MAX1464 evaluation kit (EV kit) is designed to evaluate
the MAX1464 high-performance, low-power, low-noise
multichannel sensor signal processor. The EV kit
includes: an evaluation PCB, the EV board that contains
a MAX1464 signal conditioner with a typical application
circuit, and potentiometers that act as sensor inputs to
the MAX1464; an interface PCB, KEY, which acts as a
voltage level translator between the EV kit and the com-
puter; a parallel-port extension cable; plus, supporting
software, program examples, and related documenta-
tion and application notes.
The DB25 pin connector allows a PC’s parallel port to
provide the interface. Two Windows
®
-based software
(hardware debugger and control program) provide a
friendly graphics user interface (GUI) to utilize the fea-
tures of the MAX1464, as well as to perform sensor
compensation of one device. The
Hardware Debugger
program includes multiple tabs for accessing relevant
registers and ports, writing programs to the on-chip flash
memory, downloading flash memory contents into a file,
etc. Use the
Hardware Debugger
program to learn the
MAX1464 functions and see the significance of individ-
ual registers and ports. The
Control
program includes
functional buttons to have the chip perform a series of
predefined lower level operations, such as pushing sin-
gle buttons to read the ADC. The
Control
program can
be used to perform 2nd-order sensor compensation and
calibration.
The EV board can be powered by either a fixed +5V
supply or by an +8V to +40V supply that is regulated to
+5V by a regulator present on the EV kit board before it
is applied to the MAX1464 chip. Jumper JU1 must be
set consistently with the used power supply.
Order the MAX1464 EV kit for comprehensive evaluation
of the MAX1464 using a PC with an available parallel port.

Quick Start
Required Equipment
•
•
•
MAX1464 EV kit
A fixed +5VDC power supply
Computer running Windows 98/NT/2000/XP with an
available parallel port (USB-to-parallel-port convert-
ers not supported)
A multimeter
One parallel (printer) cable
4) Press the
Flash Memory
tab in the
Hardware
Debugger
window.
5) Press
Load Buffer from file
tab.
6) Select
… | MAX1464 | examples | cctmr1-64.hex
file to read the .hex file and save it in the temporary
buffer.
7) Press
Write to device
tab to write the cctmr1-64.hex
program to the flash memory.
8) Press
Verify device against buffer
to verify that the
flash memory write operation is successful.
9) Execute the LED double-blinking program by
pressing on the
Run CPU
button. The LEDs start
blinking. This process verifies that the EV kit con-
nections are correct, the EV board jumpers are set
correctly, and the computer interface is working.
Example of Using the Control Program
Note:
Exit the
Hardware Debugger
before starting the
Control
program.
This section demonstrates how to start the
Control
program and make the basic measurement of the input
voltage.
1) Start the
Control
program from
Start | MAX1464
EV kit | Control Program.
2) A window (Figure 2) appears on the monitor.
3) The
DUT?
button turns green if the hardware setup
is correct and communication with the MAX1464 is
established. A red button indicates a hardware
and/or setup problem. The next few steps detail
reading the signal applied on the MAX1464 input
and write to the
Data Array,
which is the input to
the compensation algorithm.
4) Set the value of
This Temp Point
and
This Press
Point
to match one of the test conditions displayed
in the
Data Array.
5) Press the
Read ADC
button to convert the on-chip
temperature sensor output and channel 1 input volt-
age and display the results of both conversions in
the
Data Array.
6) To read other input voltages, adjust VR1 and VR2
potentiometers and repeat steps 5 and 6.
7) Refer to the MAX1464
Control
program manual for
a full description of
Control
program capabilities.

Procedures
Applying Power to the MAX1464 EV Board
1) Verify that all jumpers on the EV kit board are set
per the default setting shown in Table 1.
2) Connect a fixed +5V power supply to the EV kit
board TB2 +5V terminal.
3) The LEDs on the EV kit board start blinking. The
MAX1464 EV kit is shipped with a program,
EVTEST1.hex, preloaded in the MAX1464 flash
memory. This program alternatively flashes the two
LEDs on the EV board.
Setting Up for Digital Communication
1) Download the latest MAX1464 software from the
Maxim website.
2) Start the
INSTALL.EXE
program and follow the
instructions to install all MAX1464 applications pro-
grams and to copy supporting files to your computer.
3) Set up the MAX1464 EV kit by connecting the EV
board and the KEY using the 16-pin ribbon cable.
Connect the KEY to the PC’s parallel port using a
25-pin straight-through, female-to-male cable.
Example of Using the Hardware Debugger
1) Start the
Hardware Debugger
program from
Start |
MAX1464 EV kit | Hardware Debugger.
2) A window (Figure 1) appears on the monitor.
3) Read the text in the window next to the
Check CPU
status
on the top row and verify that it reads
Running
or
Halted.
Any other reading indicates a
hardware and/or setup problem. Fix the problem
before continuing to the next step. The next few
steps detail loading a new LED double blinking pro-
gram to the MAX1464 flash memory and running it.

MAX1464 Evaluation Kit
Evaluates: MAX1464
Detailed Software Description
Two independent programs have been provided for the
MAX1464 to aid the user in evaluating and designing in
the MAX1464 signal conditioner into a product.
ADC Module
In this window, users can access the ADC control, ADC
configuration, and ADC data registers for all three chan-
nels (channel 1, channel 2, and temperature sensor).
Hardware Debugger
The hardware debugger program includes multiple
tabs for accessing the relevant registers and ports,
writing programs to the on-chip flash memory, down-
loading flash memory contents into a file, etc. Use the
hardware debugger program to learn the MAX1464
functions, registers, and ports.
DOP Module
In this window, users can access the DOP control, DOP
configuration, and DOP data registers for both output
channels and the op amp configuration register.
Other Modules
In this window, users can access registers related to
the timer, power control, oscillator, and GPIOs.
CPU Registers r0..rf, p0..pf
In this window, users can read/write the CPU (module)
registers, program counter r0, r1. Users can also
read/write the CPU ports p0 through pf when the CPU is
halted.
Flash Memory
This window can be used for all flash-memory opera-
tions, such as writing flash memory to/from a file.
Program Listing
In this window, users can view the list file of an assem-
bly program. Select the filename from the
File
pulldown
menu.

MAX1464 Evaluation Kit
Control Program (MAX1464 Main.exe)
The
Control
program includes functional buttons to have
the MAX1464 perform a series of predefined lower level
operations, such as reading the ADC, loading a file into
flash memory, etc. The
Control
program can be used to
perform a 2nd-order temperature compensation.
The main purpose of the
Control
program is to provide
the user with a tool to easily compensate a sensor.
The compensation algorithm defined in Application
Note 3649,
MAX1464 Signal-Conditioner, Sensor
Compensation Algorithm,
has been implemented. All the
user needs to do is to properly set up the EV kit/sensor
and the environment condition for the sensor, and press
the
Read ADC
and
Characterize DAC
buttons at each
environment condition to fill the
Data Array
with valid
data. Then by pressing three more buttons, the compen-
sation coefficients are created and copied into the
MAX1464 flash memory, creating a compensated sensor.
Refer to the
Control Program User Manual
for a detailed
description of each function/button and how to perform
sensor compensation.
Detailed Hardware Description
A complete set of hardware is included in the MAX1464
EV kit package. A MAX1464 EV board, a MAX1464
KEY, a 16-pin ribbon cable, a parallel-port extension
cable, and a few MAX1464 samples are included in the
MAX1464 EV kit package. The MAX1464 EV kit board is
designed to give the user the most flexibility and con-
trol over the MAX1464. The user can use a fixed +5V or
an +8V to +40V power supply to power up the EV kit
board. All critical pins are easily accessible. Two
potentiometers are provided to emulate a sensor output
and allow positive and negative input signals to the
MAX1464, eliminating the need for an actual sensor
while checking the functionality of the MAX1464. A small
area with plated-through holes is intended to facilitate
building a small application circuit. And, wherever pos-
sible, jumpers have been added to offer flexibility for
configuring the EV kit board for user applications.
