A54SX32A-1CQ208B

The Microchip Technology A54SX32A-1CQ208B is an antifuse FPGA belonging to the SX-A family, designed for high-reliability applications. It is built on a single-chip, non-volatile antifuse technology, offering 32,000 typical system gates, deterministic timing, and live-at-power-up functionality. This eliminates the need for external configuration memory.

The -1 speed grade ensures fast internal and I/O performance. The device is housed in a 208-lead ceramic quad flat pack (CQFP), enabling reliable operation in extreme temperature and vibration environments. The B suffix indicates a military temperature range of -55°C to +125°C and compliance with high-reliability screening, suitable for programs referencing MIL-STD-883 requirements.

Key technical specifications include 48,000 gates, 2,880 LABs/CLBs, 174 I/O pins, and an operating voltage range of 2.25V to 5.25V. The mounting type is surface mount. Typical uses include space payload processors, avionics flight controls, military radar signal processing, and encrypted communications equipment.

Due to its one-time programmable nature, design changes require new hardware, emphasizing the need for thorough verification before commitment. Microchip supports the SX-A family with long-term availability for defense and aerospace programs. Procurement teams should consider the mature lifecycle and plan for sustained sourcing, ensuring traceability and anti-counterfeiting practices for ceramic-packaged components.
