Regulatory Compliance

The ADSP-21375 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-21375 EZ-KIT Lite 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-21375 EZ-KIT Lite has been appended to Analog Devices,

Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated

December 21, 1997 and was awarded CE Certification by an appointed

European Competent Body as listed below.

Technical Certificate No: Z600ANA1.027

Issued by: Technology International (Europe) Limited

60 Shrivenham Hundred Business Park

Shrivenham, Swindon, SN6 8TY, UK

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-21375 EZ-KIT Lite Evaluation System Manual ix

PREFACE

Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog

Devices, Inc. evaluation system for ADSP-21375 SHARC®processors.

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 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

VisualDSP++®development environment to test the capabilities of the

ADSP-21375 SHARC processors. The VisualDSP++ development envi-

ronment gives you the ability to perform advanced application code

development and debug, such as:

• Create, compile, assemble, and link application programs written

in C++, C, and ADSP-21375 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

x ADSP-21375 EZ-KIT Lite Evaluation System Manual

Access to the ADSP-21375 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-21375 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/.

LThe ADSP-21375 EZ-KIT Lite installation is part of the Visu-

alDSP++ installation. The EZ-KIT Lite is a licensed product that

offers an unrestricted evaluation license for the first 90 days. For

details about evaluation license restrictions after the 90 days, refer

to “Evaluation License Restrictions” on page 1-7.

ADSP-21375 EZ-KIT Lite provides example programs to demonstrate the

capabilities of the evaluation board.

The board features:

• Analog Devices ADSP-21375 processor

D208-pin MQFP package

D266 MHz core clock speed

• Synchronous dynamic random access memory (SDRAM)

D2M x 16-bit x 4 banks

• Flash memory

D1M x 8-bit
