AX250-1CQ208M

The AX250-1CQ208M is a high-reliability, radiation-tolerant field-programmable gate array (FPGA) from Microchip Technology’s Axcelerator family, built on antifuse technology for mission-critical digital logic in military, aerospace, and industrial environments. Its antifuse architecture provides inherent single-event upset (SEU) immunity and true live-at-power-up operation, eliminating configuration memory errors and boot-time vulnerabilities. The device is housed in a 208-lead ceramic quad flat pack (CQFP) rated for the full military temperature range of -55 °C to +125 °C, offering a hermetically sealed, ruggedized form factor suitable for extreme thermal and mechanical stress. Speed grade -1 denotes standard performance within the family, while the non-volatile, one-time programmable fabric ensures high security against reverse engineering and tampering.

This FPGA is typically integrated into flight control avionics, satellite payload processors, secure communications encryption modules, missile guidance systems, and radar signal processing chains where deterministic, instant-on logic is essential. From a procurement standpoint, the “M” suffix confirms military-grade screening and HiRel qualification, distinguishing it from commercial variants and reducing the risk of counterfeit or downgrade parts. Long product lifecycles and extended temperature characterization align with defense program requirements, but allocation and extended lead times are common for this class of component. Engineers and supply-chain teams should prioritize sourcing through authorized Microchip channels to maintain full traceability, export compliance, and hermetic package integrity.
