Regulatory Compliance
The ADSP-BF706 EZ-KIT Mini 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-BF706 EZ-KIT Mini is in the process of being certified to
comply with the essential requirements of the European EMC directive
2004/108/EC and therefore carries the “CE” mark.
The EZ-KIT Mini 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 Mini boards in the protective shipping
package.

PREFACE
Thank you for purchasing the ADSP-BF706 EZ-KIT Mini™, Analog
Devices, Inc. low-cost evaluation system for the ADSP-BF706 Blackfin®
processors.
The ADSP-BF706 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 Mini is shipped with all of the necessary hardware—you can
start the evaluation immediately. The package contains the standalone
evaluation board and USB cable. The EZ-KIT Mini ships with an
on-board debug agent.

Product Overview
x ADSP-BF706 EZ-KIT Mini 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-BF706 Blackfin processor. 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-BF706 processor
• 88-Lead LFCSP (QFN) package
• 25 MHz CLKIN core crystal
• Quad SPI Flash (SPI2)
• 32M bit serial flash memory
• Winbond W25Q32
