A42MX09-PQ100I

An end-of-life flash FPGA from Microchip’s legacy MX family (originally developed by Actel), the A42MX09-PQ100I provides 9,000 system gates of non-volatile, single-chip logic in a 100-pin PQFP industrial-grade package. The device stores its configuration on-chip in flash memory, eliminating the need for an external boot PROM and delivering instant-on operation at power-up—attributes valued in systems that cannot tolerate configuration delays or additional memory components. Manufactured for the -40°C to +85°C industrial temperature range, this part is officially discontinued by Microchip and is no longer in production.

Typical deployments include legacy industrial controllers, secure defense communication nodes, avionics line-replaceable units, and other high-reliability applications where a form-fit-function replacement of the original FPGA avoids costly board redesign and system recertification. For these long-fielded platforms, ZZX Electronics sources sustaining stock with full date-code traceability, ensuring procurement teams receive authentic devices for maintenance and repair. The non-volatile flash architecture also contributes to low static power and inherent security against configuration bitstream interception—advantages that remain relevant in extended-life programs. When a drop-in obsolete part is the practical path forward, the A42MX09-PQ100I represents a critical bridge for industrial and defense sustainment.
