A54SX72A-1PQG208I

The A54SX72A-1PQG208I is a radiation-tolerant field-programmable gate array (FPGA) from Microchip Technology’s SX-A family, built on a non-volatile antifuse process technology. The SX-A architecture delivers instant-on capability without a configuration PROM, eliminating bitstream exposure and enhancing system reliability. This device, specified with a -1 speed grade, is housed in a 208-lead plastic quad flat pack (PQFP) and operates over the industrial temperature range, providing a compact, surface-mountable form factor for space-constrained high-reliability designs. The antifuse cells inherently resist single-event upsets and latch-up, while the radiation-tolerant silicon process targets moderate total ionizing dose environments typical of low-earth orbit and high-altitude avionics.

Typical applications include satellite bus control, payload data processing, secure military communications, and flight-critical avionics systems where deterministic power-up behavior and resistance to radiation effects are mandatory. Additional end uses cover radiation-hardened industrial controllers and scientific instrumentation deployed in harsh environments. From a procurement perspective, the ‘I’ suffix denotes industrial grade –40°C to +85°C operation, and the baseline radiation-tolerant design serves as an alternative to fully QML-V qualified components when program risk profiles permit. Engineers should assess long-term lifecycle support, as antifuse FPGA families may face constrained supply chains; verifying Microchip’s product longevity status and migration roadmap is advised for new designs with extended deployment timelines.
