Regulatory Compliance
The ADSP-21371 EZ-KIT Lite is designed to be used solely in a labora-
tory 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-21371 EZ-KIT Lite has been certified to comply with the
essential requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The ADSP-21371 EZ-KIT Lite has been appended to Analog Devices,
Inc. EMC Technical File (EMC TF) referenced DSPTOOLS1 and was
declared CE compliant by an appointed Notified Body (No.0673) as
listed below.
Notified Body Statement of Compliance: Z600ANA2.040 dated
June 22 2010.

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
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 EZ-KIT Lite boards in the protective
shipping package.

ADSP-21371 EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-21371 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC®processors.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated I/O processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
The evaluation system is designed to be used in conjunction with the
CrossCore®Embedded Studio (CCES) and VisualDSP++®development
environments to test capabilities of the ADSP-21371 SHARC processors.
The development environment aids advanced application code develop-
ment and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21371 assembly
• Load, run, step, halt, and set breakpoints in application program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Access to the ADSP-21371 processor from a personal computer (PC) is
achieved through a USB port or an external JTAG emulator. The USB
interface provides unrestricted access to the ADSP-21371 processor and
