XC2S50-5-FG256I, Xilinx

The Spartan®-II Field-Programmable Gate Array family
gives users high performance, abundant logic resources,
and a rich feature set, all at an exceptionally low price. The
six-member family offers densities ranging from 15,000 to
200,000 system gates, as shown in Table 1. System
performance is supported up to 200 MHz. Features include
block RAM (to 56K bits), distributed RAM (to 75,264 bits),
16 selectable I/O standards, and four DLLs. Fast,
predictable interconnect means that successive design
iterations continue to meet timing requirements.
The Spartan-II family is a superior alternative to
mask-programmed ASICs. The FPGA avoids the initial cost,
lengthy development cycles, and inherent risk of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary (impossible with ASICs).
