XC2C512-7FT256I

XC2C512-7FT256I is a Xilinx CoolRunner-II CPLD. It provides 512 macrocells in a compact device for glue logic, simple state machines, and interface controllers, optimized for very low power. The -7 speed grade indicates one of the faster options in the family. It comes in a 256-pin FineLine TQFP package (FT256) and is rated for industrial temperature (I). The configuration is antifuse-based and non-volatile, so once programmed it cannot be reconfigured and requires no external configuration memory. Features include programmable interconnect, distributed RAM, flip-flops, and multiple I/O banks suitable for typical 3.3V I/O signals. Common applications are logic glue between microcontrollers or ASICs, small interface controllers, and other mid-density logic needs where low power and quick time-to-market matter. Design flows use Xilinx ISE for synthesis and place-and-route, with standard timing constraints. In short: a compact, low-power, non-volatile CPLD in a 256-pin industrial package, ideal for mid-density, non-reconfigurable logic.
