Spartan-3 FPGA — 5 million gates for medium-density logic
The Xilinx XC3S5000-4FGG1156C is a Spartan®-3 series FPGA packing 5,000,000 gates and 74,880 logic cells in a surface-mount package. With 633 user I/O and 1,916,928 bits of block RAM, it handles moderate digital designs — think soft-core processor plus peripheral glue, video line buffers, or multi-channel data acquisition — without reaching for a larger die. Core supply runs at 1.14 V, which keeps dynamic power in check for the gate count.
633 I/O — what it means for the board layout
633 user I/O pins are available. Each I/O bank operates at its own Vccio, supporting multiple voltage domains.
Active lifecycle — no LTB pressure
The XC3S5000-4FGG1156C carries an Active product status. No official successor is listed.
