The A54SX32A-1CQ84B is a radiation-tolerant field-programmable gate array (FPGA) from Microchip Technology’s SX-A family, engineered for high-reliability environments where conventional SRAM-based FPGAs are susceptible to configuration upsets. Fabricated on an antifuse process, this single-chip device is nonvolatile and live at power-up, eliminating the need for external configuration memory and providing inherent single-event upset (SEU) immunity in the configured logic. The component is housed in an 84-lead ceramic quad flat pack (CQFP), a ruggedized package suited to demanding thermal and mechanical conditions. As a member of the SX-A family, it offers deterministic timing, fine-grained architecture, and performance suitable for glue logic, interface bridging, and control path integration in systems requiring both radiation tolerance and low power. The “-1” suffix designates a standard speed grade, providing a balanced trade-off between switching performance and power dissipation.
Typical deployment scenarios span satellite bus electronics, deep-space instrumentation, missile guidance processors, and military avionics where extended temperature range and long mission lifetimes are mandatory. The device is often selected for its immediate signal integrity and reliable cold-sparing behavior in redundant architectures. From a procurement perspective, this FPGA occupies a class of military/aerospace-grade components with extended product longevity support; Microchip continues to supply many legacy Actel families, yet design teams should evaluate lifetime buy requirements and qualification pedigree availability. The ceramic CQFP package and rad-tolerant attributes position the part for applications governed by ITAR or similar trade controls, making traceability and authorized distribution chains critical considerations for compliance and counterfeit mitigation.
