XC5VLX20T-1FF323C

XC5VLX20T-1FF323C is a Xilinx Virtex-5 LX FPGA. It’s a mid-range device in the Virtex-5 family, aimed at digital logic, DSP, and data-path tasks.
Key points:
- Fabric: programmable logic (LUTs/flip-flops), DSP slices, and block RAM for mix of logic, math, and memory.
- Size/speed: LX20T roughly around 20k logic cells; -1 speed grade (standard performance).
- Package: FF323C — a 323-pin flip-chip BGA; -T typically denotes a Tape & Reel option.
- I/O: multiple configurable I/O banks with various voltage domains; supports common interfaces and memory/datapath peripherals.
- Tools: designed with Xilinx ISE (older toolchain); newer workflows target 7-series/UltraScale, but Virtex-5 is considered legacy.
- Use cases: DSP, embedded control, prototyping, moderate-scale custom logic, and interfaces requiring decent parallelism.
Notes:
- It’s a legacy device; for new designs, consider newer families for longer-term support and tooling.

XC5VLX20T-1FF323C is a Xilinx Virtex-5 LX FPGA in a 323-ball FF323C flip-chip package. Key features (concise):
