A42MX24-PLG84M

The A42MX24-PLG84M is a flash-based field-programmable gate array (FPGA) from Microchip Technology’s MX family, delivering a non-volatile, single-chip logic platform for high-reliability embedded systems. Built on a 0.45 µm antifuse-derived flash process, this device integrates approximately 24,000 system gates within a rugged 84-lead PLCC surface-mount package. Its instant-on, live-at-power-up capability eliminates the need for external configuration memory, while in-system reprogrammability supports iterative design refinement without hardware changes. The PLCC package offers a mechanically robust footprint with a predictable solder joint profile, suitable for moderate I/O density designs that prioritize long-term field dependability over miniaturization.

Typical integration roles span military avionics, radar processing, secure communications, and industrial motor control where guaranteed operation across the full −55 °C to +125 °C temperature range is essential. The -M suffix designates military-grade screening and compliance with microcircuit qualification flows, making the device appropriate for programs governed by DESC or MIL-STD-883 requirements. As a mature product in Microchip’s long-lifecycle portfolio, the A42MX24-PLG84M helps mitigate obsolescence risk in extended-life defense and aerospace platforms. Procurement personnel should verify authorized supply chain provenance to ensure full traceability and genuine Microchip fabrication, as this high-reliability component demands authentic material to uphold stringent quality and reliability benchmarks.
