The XC3S200-4VQG100 is a field-programmable gate array (FPGA) device from Xilinx. It is part of the Spartan-3 series and offers 200,000 gates (equivalent to a 0.2 million equivalent gate (MEG) capacity) in a 9x9 mm package. It provides system designers with a low-cost platform to implement designs with one-time programmable (OTP) and complex system functions. The device is ideal for applications that require a balance of performance, cost, and power efficiency. It includes the Virtex II Pro FPGA feature set, providing designers with additional flexibility. It also includes selectable I/O voltages, integrated power-on reset circuit, and integrated phase-locked loops (PLLs) for maximum system performance.
