Hardware / FPGA

1. Basic Info

The FPGA (Field-Programmable Gate Array) on the FITkit is a XC3S50-4PQ208C Spartan 3 family programmable gate array manufactured by Xilinx.

• interface: up to 124 user-defined I/O, supports up to 23 different I/O standards

• 192 configuravble logical blocks (CLBs) arranged into a matrix of 16 rows and 12 columns, 1728 logic cells, 50000 logic gates

• 12kb distributed RAM, 72kb RAM in a single block

• 2 digital clock managers (DCMs)

• 4 double-port block RAM memories (BRAM) with the capacity of 2kB

• 4 18x18-bit multiplier units

The PQ208 package was selected on purpose - it is cheaper and easier to mount. The Spartan-3 and Virtex families represent modern solutions in reconfigurable logic devices. Whereas the Spartan-3 devices are intended for general applications the Virtex family offers high performance for specific tasks.
