Regulatory Compliance
The CPA(Control Processor Assembly) is designed to be used solely in a laboratory environment. The board is not
intended for use as a consumer-end product or as a portion of a consumer-end product. The board is an open
system design, which does not include a shielded enclosure and, therefore, may cause interference to other electrical
devices in close proximity. This board should not be used in or near any medical equipment or RF devices.

3
The CPABoardcontains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the
human body and equipment and can discharge without detection. Permanent damage may occur on devices
subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or
loss of functionality. Store unused boards in the protective shipping package.

1Preface
Thank you for purchasing the Analog Devices, Inc. CPA development Board evaluation system.
The ADSP-CM419F processor is based on the ARM® Cortex®-M4 processor core with floating point unit
operating at frequencies up to 240 MHz core clock, and the ARM® Cortex-M0 TM processor core operating at
frequencies up to 100 MHz system clock. The processors integrate up to 192K Bytes of SRAM memory with ECC,
up to 1M Byte of flash memory with ECC, accelerators and peripherals optimized for motor control and photo-
voltaic (PV) inverter control, and an analog front end consisting of up to two 6 times simultaneous sampling 16-bit
SAR-type ADCs, one 14-bit SAR monitor ADC and one 12-bit DAC. The CPA board ships with all of the
necessary hardware to get you up and running and start the evaluation immediately.
The CPA contains an analog interface and digital interface. The evaluation board is designed to be used in
conjunction with the IAR Embedded Workbench®and Segger® development environment for advanced application
code development and debug such as:
•Create, compile, assemble, and link application programs written in C++, C, and assembly
•Load, run, step, halt, and set breakpoints in application programs
•Read and write data and program memory
•Read and write core and peripheral registers
However it can work with other development environments like Eclipse\Gcc etc.
Purpose of This Manual
This manual provides instructions for installing the product hardware (board). The text describes operation and
configuration of the board components and provides guidelines for running code on the board.
Intended Audience
The primary audience for this manual is a programmer who is familiar with an ARM Cortex-M4 core. The ADSP-
CM41x family of mixed-signal control processors is based on the ARM Cortex-M4 core.

7
For additional information about the Analog Devices processor, see the Hardware Reference Manual. The document
describes the core and memory architecture of the ADSP-CM41x processor, but does not provide detailed
programming information for the ARM core.
The applicable documentation for programming the ARM Cortex-M4 core includes:
• Cortex-M4 Devices Generic User Guide
• CoreSight ETM-M4 Technical Reference Manual
• Cortex-M4 Technical Reference Manual
For more information about programming the ARM core, visit the ARM Information Center:
