XC2C32A-4VQG44C

XC2C32A-4VQG44C is a Xilinx CoolRunner-II family antifuse-based CPLD (Complex Programmable Logic Device). It provides 32 macrocells for implementing glue logic, small state machines, decoders, and interface logic in a single device. The -4VQG44C suffix indicates a 44-pin VQFP package and a specific speed grade; the device uses non-volatile antifuse configuration, programmed in-system (typically via JTAG) but is one-time programmable (not reconfigurable like RAM-based FPGAs). It offers low static power and a compact, deterministic timing model with an integrated clocking/routing network. I/O supports common CMOS logic levels within the device’s supply range.
Typical design flow: write Verilog/VHDL, synthesize, map to 32 macrocells, generate a configuration bitstream, and program with Xilinx tools.
Common applications: glue logic, small controllers, decoders, and interface bridges for cost- and space-constrained embedded systems.
For exact electrical specs, timing, I/O standards, and package details, consult the XC2C32A datasheet and user guide.
