A54SX32A-1CQ208B

The Microchip Technology A54SX32A-1CQ208B is an antifuse FPGA from the SX-A family, designed for high-reliability applications where instant-on operation and radiation hardness are required. Built on a single-chip, non-volatile antifuse technology, it offers 32,000 typical system gates, deterministic timing, and live-at-power-up functionality, eliminating the need for external configuration memory. The -1 speed grade provides fast internal and I/O performance, and the 208-lead ceramic quad flat pack (CQFP) enables reliable operation in extreme temperature and vibration environments.

Typical uses include space payload processors, avionics flight controls, military radar signal processing, and encrypted communications equipment. The B suffix indicates military temperature range (-55°C to +125°C) and compliance with high-reliability screening, making it suitable for programs referencing MIL-STD-883 requirements. Because the device is one-time programmable, design changes require new hardware, so thorough verification is essential before commitment. Microchip supports the SX-A family with long-term availability for defense and aerospace programs, but procurement teams should consider the mature lifecycle and plan for sustained sourcing, ensuring traceability and anti-counterfeiting practices for ceramic-packaged components.
