Regulatory Compliance

The SHARC EZ-Extender is designed to be used solely in a laboratory

environment. The board is not intended for use as a consumer end prod-

uct 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 SHARC EZ-Extender has been certified to comply with the essential

requirements of the European EMC directive 89/336/EEC (inclusive

93/68/EEC) and, therefore, carries the “CE” mark.

The SHARC EZ-Extender has been appended to Analog Devices, Inc.

EMC Technical File (EMC TF) referenced “DSPTOOLS1” dated

December 21, 1997 and was declared CE compliant by an appointed

Notified Body (No.0673) as listed below.

The SHARC EZ-Extender 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 precau-

tions are recommended to avoid performance degradation or loss of func-

tionality. Store unused extender boards in the protective shipping package.

PREFACE

Thank you for purchasing the SHARC®EZ-Extender®, Analog Devices

(ADI) extension board to the EZ-KIT Lite®evaluation system for

ADSP-21262 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 SHARC the bandwidth for sustained high-speed

computations. SHARC represents today’s de facto standard for float-

ing-point processors targeted for premium audio applications.

The SHARC EZ-Extender is designed to be used in conjunction with the

CrossCore®Embedded Studio (CCES) and VisualDSP++®software

development environments. The development environment facilitates

advanced application code development and debug, such as:

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

in C++, C, and SHARC EZ-Extender 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

Product Overview

viii SHARC EZ-Extender Manual

Example programs are available to demonstrate the capabilities of the

SHARC EZ-Extender board.

Product Overview

The SHARC EZ-Extender is a separately sold assembly that plugs onto

the expansion interface of the ADSP-21262 EZ-KIT Lite evaluation

system.

The board extends the capabilities of the evaluation system by providing a

connection between the parallel data access port (PDAP) of the

ADSP-21262 processor and an Analog Devices analog-to-digital

high-speed converter (ADC HSC) evaluation board. Moreover, the

extender broadens the range of the EZ-KIT Lite applications by providing

surface-mounted (SMT) footprints for breadboard capabilities and access

to all of the pins on the EZ-KIT Lite’s expansion interface.

The extender features:

• High-speed converter evaluation board interface

• 40-pin, right angle, 0.1 in. spacing, female socket to con-

nect to analog-to-digital converter boards

• Switches for routing and direction selection

• RJ-45 with serial peripheral interconnect (SPI) to configure

converter registers

SHARC EZ-Extender Manual ix

Preface

• SMT footprint area

• 1206 and 805 footprints

• SOIC24 and SOIC20 footprints

• Dimensions

• 5 in (H) x 5 in (W)

Purpose of This Manual

The SHARC EZ-Extender Manual describes the operation and configura-

tion of the components on the board. A schematic and a bill of materials

are provided as a reference for future ADSP-21262 processor board

designs.

Intended Audience

This manual is a user’s guide and reference to the SHARC EZ-Extender.

Programmers who are familiar with the Analog Devices SHARC processor

architecture, operation, and development tools are the primary audience

for this manual.

Programmers who are unfamiliar with Analog Devices processors can use

this manual but should supplement it with other texts that describe your

target architecture. For the locations of these documents, see “Related

Documents”.

Programmers who are unfamiliar with CCES or VisualDSP++ should refer

to the online help and user’s manuals.
