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
Issued by: Technology International (Europe) Limited

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.

ADSP-21262 EZ-KIT Lite Evaluation System Manual ix
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

Product Overview

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
http://www.analog.com/dsp/tools.
The ADSP-21262 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.

Purpose of This Manual
xii ADSP-21262 EZ-KIT Lite Evaluation System Manual
The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2M bit of SPI flash memory. Flash memories can store user-specific boot
code, allowing the board to run as a stand-alone unit. For more informa-
tion, see “External Memory” on page 1-12 and “Boot Mode and Clock
Ratio Select Switch (SW10)” on page 2-11. The board also has 512 KB of
SRAM, which can be used at runtime.
The DAI of the processor connects to the AD1835A audio codec and the
CS8416 S/PDIF receiver. These devices facilitate creation of digital and
analog audio signal processing applications. See “Analog Audio Interface”
on page 1-13 and “Digital Audio Interface” on page 1-14 for more
information.
Additionally, the EZ-KIT Lite board provides access to all of the proces-
sor’s peripheral ports. Access is provided in the form of a three-connector
expansion interface. See “Expansion Interface” on page 2-7 for details.
Purpose of This Manual
The ADSP-21262 EZ-KIT Lite Evaluation System Manual provides
instructions for installing the product hardware (board). The text
describes operation and configuration of the board components and pro-
vides guidelines for running your own code on the ADSP-21262 EZ-KIT
Lite. Finally, a schematic and a bill of materials are provided as a reference
for future designs.
Intended Audience
The primary audience for this manual is a programmer who is familiar
with Analog Devices processors. This manual assumes that the audience
has a working knowledge of the appropriate processor architecture and
instruction set.
