Regulatory Compliance
The EV-21569-SOM evaluation board 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 sys-
tem 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.
The EV-21569-SOM evaluation board contains 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 perform-
ance degradation or loss of functionality. Store unused boards in the protective shipping package.

1 Preface
Thank you for purchasing the Analog Devices, Inc. System-on-Module (SoM) EV-21569-SOM evaluation board.
The EV-21569-SOM primarily hosts the ADSP-21569 audio processor, 8 Gbit of ISSI DDR3 memory, a 512 Mbit
Quad SPI FLASH, voltage regulation, a FTDI UART to USB interface, and a high speed external connector array
that contains all of the peripheral I/O signals. Through the high speed external connector array, the EV-21569-SOM
is intended for use with a growing family of SoM carrier products that contain a variety of peripherals to support
different applications. The SoM carrier base products that exist today are the EV-SOMCRR-EZKIT and EV-
SOMCRR-AUTO .
The CrossCore Embedded Studio®(CCES) software development tool chain is required for a full evaluation of this
hardware platform. The EV-21569-SOM can also be used in a limited standalone mode while not plugged into a
SoM Carrier such as the EV-SOMCRR-EZKIT or EV-SOMCRR-AUTO . The standalone mode is useful for evaluat-
ing the CCES Software Development Tools and benchmarking software algorithms that do not require peripheral
I/O.
The evaluation board is designed to be used in conjunction with the CCES 2.9.3 (or newer) development environ-
ment for advanced application code development and debug, with features that enable the ability to:
•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
Purpose of This Manual
This manual provides instructions for installing the product hardware (board). This manual describes operation and
configuration of the board components and provides guidelines for running code on the board.
Manual Contents
The manual consists of:
•Using the board
