FPGA Software and Firmware
1-2 Blackfin FPGA EZ-Extender Manual3. Remove any rubber feet attached to the EZ-KIT Lite if the feet 
cover the printed circuit board (PCB) mounting holes. In place of 
the rubber feet, install the four nylon feet and screws provided with 
the FPGA EZ-Extender. Install the nylon feet in the mounting 
holes of the EZ-KIT Lite’s PCB. Flip the EZ-KIT Lite upside 
down so that the three expansion headers (
J1–3) are facing up.

FPGA EZ-Extender Overview
The Blackfin FPGA EZ-Extender connects a Xilinx® Spartan III 
Field-Programmable Gate Array (FPGA for short) to the ADSP-BF533, 
ADSP-BF537, or the ADSP-BF561 EZ-KIT Lite. The FPGA connects to 
the Blackfin processor via the expansion interface.
The extender board, by default, is powered by an external 7V power sup-
ply provided with the product. You can also power the FPGA 
EZ-Extender by the expansion interface...

FPGA EZ-Extender Overview
1-4 Blackfin FPGA EZ-Extender ManualThe FPGA EZ-Extender contains 2 MB of asynchronous SRAM memory, 
powered by a 3.3V supply. The SRAM memory connects to banks 6 and 7 
of the FPGA and can perform simple data storage instructions in applica-
tion-specific code. 
The FPGA EZ-Extender includes a 25 MHz oscillator (
U6) connected to 
the FPGA via the dedicated global clock 1 (
GCLK1) pin, facilitating devel-
opment of applications that require a clock. A second clock socket (
U7)...
