XC2C512-7FT256I

XC2C512-7FT256I is a Xilinx CoolRunner-II family antifuse-based CPLD. It packs about 512 logic elements in a 256-pin FineLine package (FT256) and is designed for low power, deterministic glue logic and small digital control tasks. The device uses nonvolatile antifuse configuration (one-time programmable) and provides programmable interconnect and I/O resources suitable for implementing state machines, decoders, and peripheral interfaces. The “-7” denotes the speed grade (fast variant), and the “I” indicates industrial temperature range (-40 to 85 °C). It supports multiple I/O banks within the 256-pin package and includes global clock/reset resources for timing control. Typical applications include interfacing microcontrollers to peripherals, logic expansion, and glue logic in embedded systems. Programming is done with Xilinx tools (ISE/WebPACK, legacy flow). For full electrical characteristics, timing, and architectural details, consult the XC2C512-7FT256I datasheet and user guide on Xilinx’s website.
