Regulatory Compliance
The ADSP-BF527 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-BF527 EZ-KIT Lite is currently being processed for certifica-
tion that it complies with the essential requirements of the European
EMC directive 89/336/EEC amended by 93/68/EEC 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
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-BF527 EZ-KIT Lite Evaluation System Manual xi
PREFACE
Thank you for purchasing the ADSP-BF527 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for Blackfin®processors.
Blackfin processor family embodies a new type of embedded processor
designed specifically to meet the computational demands and power con-
straints of today’s embedded audio, video, and communications
applications. They deliver breakthrough signal-processing performance
and power efficiency within a reduced instruction set computing (RISC)
programming model.
Blackfin processors support a media instruction set computing (MISC)
architecture. This architecture is the natural merging of RISC, media
functions, and digital signal processing (DSP) characteristics. Blackfin
processors deliver signal-processing performance in a microprocessor-like
environment.
Based on the Micro Signal Architecture (MSA), Blackfin processors com-
bine a 32-bit RISC instruction set, dual 16-bit multiply accumulate
(MAC) DSP functionality, and eight-bit video processing performance
that had previously been the exclusive domain of very-long instruction
word (VLIW) media processors.

xii ADSP-BF527 EZ-KIT Lite Evaluation System Manual
The evaluation board is designed to be used in conjunction with the Visu-
alDSP++®development environment to test the capabilities of the
ADSP-BF527 Blackfin processors. The VisualDSP++ development envi-
ronment aids advanced application code development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-BF527 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-BF527 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-BF527 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-BF527 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
LThe ADSP-BF527 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 and the Visu-
alDSP++ Installation Quick Reference Card.
