Datasheet
®
PSoC
®
4 is a scalable and reconfigurable platform architecture for a family of mixed-signal programmable embedded system
controllers with an ARM
®
Cortex™-M0 CPU. It combines programmable and reconfigurable analog and digital blocks with flexible
automatic routing. The PSoC 4100 product family, based on this platform, is a combination of a microcontroller with digital program-
mable logic, high-performance analog-to-digital conversion, opamps with Comparator mode, and standard communication and timing
peripherals. The PSoC 4100 products will be fully upward compatible with members of the PSoC 4 platform for new applications and
design needs. The programmable analog and digital sub-systems allow flexibility and in-field tuning of the design.

IO Subsystem
The PSoC 4100 devices include extensive support for
programming, testing, debugging, and tracing both hardware
and firmware.
The ARM Serial_Wire Debug (SWD) interface supports all
programming and debug features of the device.
Complete debug-on-chip functionality enables full device
debugging in the final system using the standard production
device. It does not require special interfaces, debugging pods,
simulators, or emulators. Only the standard programming
connections are required to fully support debug.
The PSoC Creator Integrated Development Environment (IDE)
provides fully integrated programming and debug support for the
PSoC 4100 devices. The SWD interface is fully compatible with
industry standard third party tools. With the ability to disable
debug features, with very robust flash protection, and by allowing
customer-proprietary functionality to be implemented in on-chip
programmable blocks, the PSoC 4100 family provides a level of
security not possible with multi-chip application solutions or with
microcontrollers.
The debug circuits are enabled by default and can only be
disabled in firmware. If not enabled, the only way to re-enable
them is to erase the entire device, clear flash protection, and
reprogram the device with new firmware that enables debugging.
Additionally, all device interfaces can be permanently disabled
(device security) for applications concerned about phishing
attacks due to a maliciously reprogrammed device or attempts to
defeat security by starting and interrupting flash programming
sequences. Because all programming, debug, and test inter-
faces are disabled when maximum device security is enabled,
PSoC 4100 with device security enabled may not be returned for
failure analysis. This is a trade-off the PSoC 4100 allows the
customer to make.

Functional Definition
CPU and Memory Subsystem
CPU
System Resources
Power System
The Cortex-M0 CPU in PSoC 4100 is part of the 32-bit MCU
subsystem, which is optimized for low power operation with
extensive clock gating. It mostly uses 16-bit instructions and
executes a subset of the Thumb-2 instruction set. This enables
fully compatible binary upward migration of the code to higher
performance processors such as the Cortex-M3 and M4, thus
enabling upward compatibility. The Cypress implementation
includes a hardware multiplier that provides a 32-bit result in one
cycle. It includes a nested vectored interrupt controller (NVIC)
block with 32 interrupt inputs and also includes a Wakeup
Interrupt Controller (WIC), which can wake the processor up
from Deep Sleep mode allowing power to be switched off to the
main processor when the chip is in Deep Sleep mode. The
Cortex-M0 CPU provides a Non-Maskable Interrupt input (NMI),
which is made available to the user when it is not in use for
system functions requested by the user.
The CPU also includes a debug interface, the serial wire debug
(SWD) interface, which is a two-wire form of JTAG; the debug
configuration used for PSoC 4100 has four break-point
(address) comparators and two watchpoint (data) comparators.
Flash
The power system is described in detail in the section
Power on
page 15.
It provides assurance that voltage levels are as
required for each respective mode and either delay mode entry
(on power-on reset (POR), for example) until voltage levels are
as required for proper function or generate resets (brown-out
detect (BOD)) or interrupts (low-voltage detect (LVD)). The
PSoC 4100 operates with a single external supply over the range
of 1.71 V to 5.5 V and has five different power modes, transitions
between which are managed by the power system. PSoC 4100
provides Sleep, Deep Sleep, Hibernate, and Stop low-power
modes.
Clock System
The PSoC 4100 clock system is responsible for providing clocks
to all subsystems that require clocks and for switching between
different clock sources without glitching. In addition, the clock
system ensures that no metastable conditions occur.
The clock system for PSoC 4100 consists of the internal main
oscillator (IMO) and the internal low-power oscillator (ILO) and
provision for an external clock.
Figure 3. PSoC 4100 MCU Clocking Architecture
IMO
EXTCLK
HFCLK
PSoC 4100 has a flash module with a flash accelerator tightly
coupled to the CPU to improve average access times from the
flash block. The flash block is designed to deliver 0 wait-state
(WS) access time at 24 MHz. Part of the flash module can be
used to emulate EEPROM operation if required.
The PSoC 4200 Flash supports the following flash protection
modes at the memory subsystem level:
■
■
ILO
LFCLK
Open: No Protection.
Factory default mode in which the
product is shipped.
Protected: User may change from Open to Protected.
This
mode disables Debug interface accesses. The mode can be
set back to Open but only after completely erasing the Flash.
Kill: User may change from Open to Kill.
This mode disables
all Debug accesses. The part cannot be erased externally, thus
obviating the possibility of partial erasure by power interruption
and potential malfunction and security leaks. This is an irrecvo-
cable mode.

SYSCLK

PERXYZ _ CLK
In addition, row-level Read/Write protection is also supported to
prevent inadvertent Writes as well as selectively block Reads.
Flash Read/Write/Erase operations are always available for
internal code using system calls.
SRAM
SRAM memory is retained during Hibernate.
SROM
A supervisory ROM that contains boot and configuration routines
is provided.
The HFCLK signal can be divided down (see
PSoC 4100 MCU
Clocking Architecture)
to generate synchronous clocks for the
analog and digital peripherals. There are a total of 12 clock
dividers for PSoC 4100, each with 16-bit divide capability. The
analog clock leads the digital clocks to allow analog events to
occur before digital clock-related noise is generated. The 16-bit
capability allows a lot of flexibility in generating fine-grained
frequency values and is fully supported in PSoC Creator.
