XC2S50-5PQ208C

XC2S50-5PQ208C is a Xilinx Spartan-2 FPGA (field-programmable gate array) aimed at mid-density, low-cost logic designs. It comes in a 208-pin Plastic Quad Flat Pack (PQFP) and uses the -5 speed grade with commercial grade (-C). The “50” denotes roughly 50k system gates of programmable logic, suitable for a mix of combinational logic, state machines, simple DSP, and glue logic. It’s built around Configurable Logic Blocks (CLBs) with LUTs and flip-flops and includes carry logic, distributed RAM, and I/O blocks organized into banks for flexible external connections. The device provides a global clock network and I/O resources compatible with standard FPGA designs (commonly 3.3V I/O). Tools: supported by Xilinx ISE (older toolchain). Applications: rapid prototyping and small-to-mid-scale digital designs where cost and time-to-market matter. Note: this is an older part, largely superseded by Spartan-3/6 families; consult the datasheet and app notes for exact specifications and limits.

Direct equivalents from other vendors do not exist for XC2S50-5PQ208C. The closest drop-in options are other speed grades of the same Spartan-2 device in the 208-pin PQFP package (XC2S50 in the PQ208C family, with different speed grades). For modernization, migrate to a newer Xilinx family (e.g., Spartan-6) and use the Xilinx cross-reference tool or distributor catalogs to select a suitable replacement.

XC2S50-5PQ208C is a Spartan-2 FPGA in a 208-pin PQFP with a -5 (fast) speed grade. Key features:
- Approx. 50K system gates of programmable logic
- 208-pin PQFP package; high I/O density in this package
