XC2S50-5FGG256C

XC2S50-5FGG256C is a Xilinx Spartan-2 FPGA (field-programmable gate array). It provides a reconfigurable logic fabric suitable for small-to-mid complexity digital designs, glue logic, and embedded controllers. The “XC2S50” denotes Spartan-2 with roughly fifty thousand equivalent logic gates; “-5” is the speed grade; “FGG256” refers to a 256-pin Fine-Grid Package; “C” is the temperature grade. It includes programmable logic blocks, small RAM blocks, and multiple I/O banks for standard logic levels. It is configured at power-up from an external PROM or other nonvolatile source and programmed via Xilinx ISE toolchains. Development is supported by Xilinx ISE; programming interfaces typically include JTAG or PROM configuration. Spartan-2 devices are older technology and have been largely superseded by Spartan-6 and newer families, but XC2S50 can still be used for legacy designs where cost and availability are factors. For exact specifications (I/O counts, RAM, clocking resources), consult the device datasheet.

Equivalent products: None. XC2S50-5FGG256C is a Spartan-2 FPGA; there are no pin-for-pin or functionally equivalent newer parts. It’s obsolete. If replacement is needed, migrate to a newer Xilinx family (Spartan-3/6, Artix-7) in a suitable package, or consider PLDs/FPGA from other vendors, which will require redesign.
