Regulatory Compliance
The ADSP-CM403F EZ-KIT Lite is designed to be used solely in a labo-
ratory 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.
The ADSP-CM403F EZ-KIT Lite is in the process of being certified to
comply with the essential requirements of the European EMC directive
2004/108/EC and therefore carries the “CE” mark.
The EZ-KIT Lite evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent dam-
age may occur on devices subjected to high-energy discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of
functionality. Store unused EZ-KIT Lite boards in the protective shipping
package.

PREFACE
Thank you for purchasing the ADSP-CM403F EZ-KIT Lite®, Analog
Devices, Inc. low-cost evaluation system for the ADSP-CM403F
mixed-signal control processor.
The ADSP-CM403F processor is based on the ARM®Cortex®-M4 pro-
cessor core and is designed for photovoltaic applications. The EZ-KIT
Lite is shipped with all of the necessary hardware—you can start the eval-
uation immediately. The package contains the standalone evaluation
board and CE-approved power supply. The EZ-KIT Lite version ships
with the J-Link Lite ARM, while the EZ-Board®version requires the cus-
tomer to provide a debugger.
Two expansion connectors (analog interface and PWM/digital interface)
are provided for connecting boards that incorporate motors. Another
expansion connector is provided for connecting an Anybus board and/or a
memory/FPGA extender card.
Traditional mechanical switches for changing the board’s factory setup
have been removed in favor of I2C controlled software switches. The only
remaining mechanical switches are the boot mode switch and push
buttons.

Product Overview
