Regulatory Compliance
The ADSP-21262 EZ-KIT Lite evaluation system 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 enclo-
sure 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-21262 EZ-KIT Lite evaluation system has been certified to
comply with the essential requirements of the European EMC directive
89/336/EEC amended by 93/68/EEC and, therefore, carries the “CE”
mark.
The ADSP-21262 EZ-KIT Lite evaluation system has been appended to
Analog Devices, Inc. EMC Technical File (EMC TF) referenced
“DSPTOOLS1” dated December 21, 1997 and was declared CE compli-
ant by an appointed Notified Body (No.0673) as listed below.
Notified Body Statement of Compliance: Z600ANA1.013

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-21262 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC®processors (DSPs).
The 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 IO pro-
cessor, which gives a SHARC processor the bandwidth for sustained
high-speed computations. SHARC processors represent today’s de facto
standard for floating-point processor targeted for premium audio
applications.
The evaluation system is designed to be used in conjunction with the
CrossCore®Embedded Studio (CCES) and VisualDSP++®development
environments to demonstrate capabilities of the ADSP-21262 SHARC
processors. The development environment aids advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21262 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
• Plot memory
Access to the ADSP-21262 processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB

interface gives unrestricted access to the ADSP-21262 processor and the
evaluation board peripherals. Analog Devices JTAG emulators offer faster
communication between the host PC and target hardware. Analog Devices
carries a wide range of in-circuit emulation products. To learn more about
Analog Devices emulators and processor development tools, go to

The ADSP-21262 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
