A54SX72A-CQ256B

The A54SX72A-CQ256B is a field-programmable gate array (FPGA) from Microchip Technology’s SX-A family, built on antifuse technology and housed in a 256-lead ceramic quad flat pack (CQFP). As an antifuse-based device, it provides instant-on, live-at-power-up operation with inherent non-volatility and a highly secure configuration that resists reverse engineering. The hermetic ceramic package and military temperature range ensure reliable performance in harsh environments, while the single-event latch-up immunity characteristic of the antifuse architecture makes it suitable for radiation-exposed applications. The SX-A family delivers high-speed deterministic timing and fast clock-to-out performance, integrating a substantial logic density without requiring external configuration memory.

Typical deployment scenarios include mission-critical defense electronics, satellite systems, avionics processing, and industrial controls where deterministic power-up behavior and long-term reliability are non-negotiable. The device is often utilized in secure communication links, guidance and navigation units, and safety-critical control path implementations. From a procurement standpoint, this is a high-reliability, military/aerospace-grade component, with the CQFP package and screening options underscoring its conformance to stringent quality standards. Engineering and supply-chain teams should account for extended lead times, potential export control restrictions, and the managed lifecycle of a mature antifuse product line. Authentic sourcing through authorized Microchip distribution is essential to maintain traceability and mitigate counterfeiting risks.
