5962-0054301QYC

The Microchip Technology A54SX72A-CQ208B, identified by SMD 5962-0054301QYC, is a military-grade antifuse field-programmable gate array (FPGA) from the SX-A family, housed in a 208-lead ceramic quad flat pack (CQFP). This device employs one-time programmable antifuse interconnect technology, providing non-volatile configuration, instant-on power-up, and intrinsic single-event upset (SEU) immunity. The fabric offers 72,000 typical system gates with fine-grained logic cells, and the hermetic ceramic package supports reliable operation over extended temperature ranges under QML Class Q screening, making it suited for environments where configuration memory retention and radiation tolerance are non-negotiable.

Typical end-use scenarios include satellite payload processors, launch vehicle guidance, and avionics engine controllers, as well as defense systems such as secure communications and radar signal processing where deterministic startup and long-term reliability are essential. Industrial high-reliability applications with extreme environmental demands also benefit from this technology. From a procurement perspective, the SMD 5962-xxxxxxx number confirms adherence to a standardized defense drawing, ensuring controlled die provenance, rigorous screening, and full traceability. Microchip maintains an extended product lifecycle for mil-aerospace components, yet obsolescence awareness remains relevant when planning multi-decade programs. Authorized sourcing is critical to obtain authentic QML-certified material, complete with the necessary certification paperwork, and to mitigate the risk of counterfeit devices in regulated supply chains.
