A54SX72A-1CQ208B

The A54SX72A-1CQ208B is a radiation-tolerant field-programmable gate array (FPGA) manufactured by Microchip Technology, part of the SX-A family optimized for high-reliability aerospace and defense systems. This device delivers 72,000 system gates of antifuse-based logic in a 208-lead ceramic quad flat pack (CQFP). The antifuse architecture provides inherently non-volatile configuration that powers up instantly without external boot memory, while its radiation-hardened-by-design silicon ensures strong single-event upset (SEU) resilience and latch-up immunity under heavy ion exposure. A -1 speed grade supports fast in-system performance across temperature extremes, making it suitable for critical processing paths in constrained environments.

Typical applications include satellite on-board data handling, launch vehicle telemetry and control, deep-space instrumentation, and military avionics processors. The hermetically sealed CQFP package withstands severe thermal cycling and mechanical shock, meeting the demands of orbital and high-altitude missions. From a procurement standpoint, this FPGA occupies a specialized high-reliability semiconductor category; Microchip maintains long-term availability programs for the SX-A series, yet supply chain planning requires awareness of wafer fab allocations and extended lead times. Sourcing through authorized channels with full traceability documentation and anti-counterfeit inspection is essential for flight-model and mission-critical builds.
