Regulatory Compliance
The ADSP-BF537 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-BF537 EZ-KIT Lite has been certified to comply with the
essential requirements of the European EMC directive 89/336/EEC
amended by 93/68/EEC and therefore carries the “CE” mark.
The ADSP-BF537 EZ-KIT Lite has been appended to Analog Devices,
Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated
December 21, 1997 and was awarded CE Certification by an appointed
European Competent Body as listed below.
Technical Certificate No: Z600ANA1.021
Issued by: Technology International (Europe) Limited
60 Shrivenham Hundred Business Park
Shrivenham, Swindon, SN6 8TY, UK
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.

PREFACE
Thank you for purchasing the ADSP-BF537 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for ADSP-BF537 Blackfin®processors.
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 evaluation board is designed to be used in conjunction with the Visu-
alDSP++®development environment to test the capabilities of
ADSP-BF537 Blackfin processors. The VisualDSP++ development envi-
ronment gives you the ability to perform advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-BF537 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-BF537 processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface provides unrestricted access to the ADSP-BF537 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-BF537 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
LThe ADSP-BF537 EZ-KIT Lite installation is part of the Visu-
alDSP++ installation. The EZ-KIT Lite is a licensed product that
offers an evaluation (temporary) license. Once the evaluation
license expires, VisualDSP++ restricts simulator and emulator con-
nections and limits the size of a user program to 20 KB of internal
memory.
The board features:
• Analog Devices ADSP-BF537 Blackfin processor
DCore performance up to 600 MHz
DExternal bus performance to 133 MHz
D182-pin mini-BGA package
D25 MHz crystal
• Synchronous dynamic random access memory (SDRAM)
DMT48LC32M8 – 64 MB (8M x 8-bits x 4 banks) x 2 chips
• Flash memory
D4 MB (2M x 16-bits)
• Analog audio interface
DAD1871 96 kHz analog-to-digital codec (ADC)
DAD1854 96 kHz digital-to-audio codec (DAC)
