A54SX32A-1CQ84M

The A54SX32A-1CQ84M is a high-reliability field-programmable gate array (FPGA) from Microchip Technology’s SX-A family, built on an antifuse process and supplied in an 84-lead ceramic quad flat pack (CQFP) with a military temperature grade. Antifuse-based logic elements are inherently non-volatile and single-chip, eliminating the need for external configuration memories, which reduces board space and security attack surfaces. This architecture is also immune to single-event upsets (SEU) in configuration cells and offers live-at-power-up operation, making it suitable for deterministic control and interface functions where instant-on behavior is critical. The A54SX32A device provides 32,000 typical gates in a footprint that balances logic density with package size, while the CQFP package delivers robust thermal and mechanical performance for demanding environments.

Typical applications span defense electronics, avionics, industrial machine control, and other mission-critical systems requiring long-term availability and tolerance to extended temperature extremes. In these settings, the FPGA often performs glue logic, address decoding, secure data path management, and interface bridging in systems that must be quickly brought online and operate without configuration-bit corruption. The “M” suffix denotes military temperature range operation, making the part suitable for platform-level programs where standard commercial ratings are insufficient, though it does not automatically imply full MIL-STD-883 screening. Procurement considerations include Microchip’s extended lifecycle support and careful monitoring of factory lead times, as mil-temp ceramic-packaged FPGAs are subject to long qualification cycles. Ensuring traceability and authentic sourcing from authorized distributors is essential to avoid counterfeit and recertified devices in high-reliability supply chains.
