All other brand and product names are trademarks or service marks of
their respective owners.

Regulatory Compliance
The Blackfin FPGA EZ-Extender has been certified to comply with the
essential requirements of the European EMC directive 89/336/EEC
(inclusive 93/68/EEC) and, therefore, carries the “CE” mark.
The Blackfin FPGA EZ-Extender had been appended to Analog Devices
Development Tools Technical Construction File referenced
“DSPTOOLS1” dated December 21, 1997 and was awarded CE Certifi-
cation by an appointed European Competent Body and is on file.
The EZ-KIT Lite evaluation system contains ESD
(electrostatic discharge) sensitive devices. Electro-
static 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 Blackfin®Field-Programmable Gate Array
(FPGA) EZ-Extender®, Analog Devices, Inc. (ADI) extension board to
the EZ-KIT Lite®evaluation system for ADSP-BF533, ADSP-BF537,
and ADSP-BF561 Blackfin processors.
The 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
characteristics towards delivering signal processing performance in a
microprocessor-like environment.
The EZ-KIT Lite and FPGA EZ-Extender are designed to be used in con-
junction with the VisualDSP++®development environment.
VisualDSP++ offers a powerful programming tool with new flexibility that
significantly decreases the time required to port software code to a proces-
sor, reducing time-to-market.

Product Overview
The Blackfin FPGA EZ-Extender is a separately sold extension board that
plugs onto the expansion interface of the ADSP-BF533, ADSP-BF537, or
ADSP-BF561 EZ-KIT Lite evaluation system. The extension board aids
the design and prototyping phases of ADSP-BF533, ADSP-BF537, or
ADSP-BF561 processor targeted applications.
