XC5VSX35T-1FFG665C

XC5VSX35T-1FFG665C is a mid-density Xilinx Virtex-5 SX FPGA. Key points:
- 65 nm FPGA in a 665-ball flip-chip package (FFG665C); commercial temperature range; -1 speed grade (fastest in its family).
- Resources: roughly 35k logic cells, DSP blocks, Block RAM, and multi-gigabit transceivers (MGT) for high-speed serial I/O.
- Typical uses: high-performance DSP, telecom/data communications, RF/front-end processing, embedded systems, and prototyping.
- Tools: designed with Xilinx ISE Design Suite (Vivado does not support Virtex-5 devices).
- Resources and transceiver specs are best confirmed in the official datasheet and packaging guides (DS/PG). Note: this is a legacy device; consider newer FPGA families if starting a new project.
If you need exact counts (logic cells, DSP slices, BRAM, MGT speeds) or pinout, consult the XC5VSX35T-1FFG665C datasheet.
