Regulatory Compliance

The Blackfin 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 Blackfin 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 Blackfin 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 Blackfin 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 Blackfin EZ-Extender®, Analog Devices

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

ADSP-BF533 and ADSP-BF561 Blackfin® processors.

The Blackfin processors are embedded processors that support a Media

Instruction Set Computing (MISC) architecture. This architecture is the

natural merging of RISC, media functions, and digital signal processing

(DSP) characteristics towards delivering signal processing performance in

a microprocessor-like environment.

The Blackfin 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 Blackfin 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

To learn more about Analog Devices development software, go to

http://www.analog.com/processors/tools.

Example programs are available to demonstrate the capabilities of the

Blackfin EZ-Extender board.

Product Overview

viii Blackfin EZ-Extender Manual

Product Overview

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

the expansion interface of the ADSP-BF533/BF561 EZ-KIT Lite evalua-

tion system.

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

connection between the parallel peripheral interface (PPI) of the

ADSP-BF533 processor (the PPI0 and PPI1 interfaces of the ADSP-BF561

processor), an Analog Devices high-speed converter (HSC) evaluation

board, a camera evaluation board, and an LCD display device. Moreover,

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

viding surface mounted (SMT) footprints for breadboard capabilities and

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

Please visit www.analog.com/EX1-Extender for additional information,

including CCES support.

The extender features:

• High-speed converter (HSC) evaluation board interface

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

nect to analog-to-digital converter (ADC) boards

• 40-pin straight, 0.1 in. spacing header to connect to digi-

tal-to-analog converter (DAC) boards

• Switches for routing and direction selection

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

converter registers
