Regulatory Compliance

The ADSP-BF707 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-BF707 EZ-KIT Lite is in the process of being certified to com-

ply with the essential requirements of the European EMC directive

2004/108/EC and therefore carries the “CE” mark.

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-BF707 EZ-KIT Lite®, Analog

Devices, Inc. low-cost evaluation system for the ADSP-BF70x Blackfin®

processors.

The ADSP-BF707 processor is a member of the Blackfin family of prod-

ucts. Blackfin processors combine a dual-MAC state-of-the-art signal

processing engine, the advantages of a clean, orthogonal RISC-like micro-

processor instruction set, and single-instruction, multiple-data (SIMD)

multimedia capabilities into a single instruction-set architecture. New

enhancements to the Blackfin+™ core add 32-bit MAC and 16-bit com-

plex MAC support, cache enhancements, branch prediction and other

instruction set improvements—all while maintaining instruction set com-

patibility to previous Blackfin products.

The EZ-KIT Lite is shipped with all of the necessary hardware—you can

start the evaluation immediately. The package contains the standalone

evaluation board, CE-approved power supply, and USB cable. The

EZ-KIT Lite version ships with an ICE-1000 emulator, while the

EZ-Board® version is supported by the ICE-1000 or ICE-2000 emulator.

Expansion Interface III is provided for connecting a camera or audio

extender board.

Traditional mechanical switches for changing the board’s factory setup

have been removed in favor of I2C controlled software switches. The only

remaining mechanical switches are the boot mode switch and push

buttons.

Product Overview

x ADSP-BF707 EZ-KIT Lite Evaluation System Manual

The evaluation board is designed to be used in conjunction with the

CrossCore® Embedded Studio (CCES) development tools to test capabil-

ities of the ADSP-BF707 Blackfin processors. The CCES development

environment aids advanced application code development and debug,

such as:

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

in C++, C, and 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

Product Overview

The board features:

• Analog Devices ADSP-BF707 processor

• 184-ball BGA package

• 25 MHz CLKIN core oscillator

• DDR2 memory (DMC0) chip

• 128M x 16-bit (2G bit)

• Micron MT47H128M16

• Quad SPI Flash (SPI2)

• 32M bit serial flash memory

• Winbond W25Q32
