The new fourth-generation SRAM-based XC5200 FPGA family from Xilinx is engineered to deliver the lowest costper- gate of any FPGA family. The Xilinx XC4000 family of FPGAs, on the other hand, offers a feature-rich architecture ideal for PCI, DSP, telecommunications, and other higherperformance applications. High-density XC4000 designs not using the XC4000 dedicated features, such as on-chip Select-RAMTM and dedicated wide edge decoders, can easily achieve significant cost reductions by migrating to the XC5200, which is 100% footprint compatible with the XC4000.
