Regulatory Compliance
The ADSP-BF506F 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-BF506F 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-BF506F EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-BF506F EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for the ADSP-BF504/BF506(F) Blackfin®
processors.
Blackfin processors embody a new type of embedded processor designed
specifically to meet the computational demands and power constraints 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.

x ADSP-BF506F EZ-KIT Lite Evaluation System Manual
The evaluation board is designed to be used in conjunction with the Visu-
alDSP++®development environment to test capabilities of the
ADSP-BF504/BF506(F) Blackfin processors. The VisualDSP++ develop-
ment environment aids advanced application code development and
debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-BF506F 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 processor from a personal computer (PC) is achieved
through a USB port or an external JTAG emulator. The USB interface
provides unrestricted access to the ADSP-BF506F processor and evalua-
tion 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-BF506F EZ-KIT Lite provides example programs to demon-
strate the evaluation board capabilities.
LAn 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 in this manual and the VisualDSP++
Installation Quick Reference Card.
