A3P250-PQG208I

The Microchip A3P250-PQG208I is a flash-based field-programmable gate array (FPGA) from the ProASIC3 family, providing 250,000 system gates in an industrial-temperature 208-pin plastic quad flat pack (PQFP) package. Its non-volatile flash configuration memory enables single-chip operation with live-at-power-up capability, eliminating the need for external boot PROMs. The device integrates 36 Kbits of embedded SRAM, 1 Kbit of FlashROM, and up to 157 user I/Os supporting a variety of single-ended and differential I/O standards. The flash-based fabric offers inherent immunity to single-event upsets (SEU) in the configuration cells, along with very low static power consumption compared to SRAM-based alternatives.

Typical deployments include industrial motor drives, secure communication equipment, and legacy aerospace/defense systems where instant-on performance, security against bitstream interception, and ruggedized operation over the -40°C to +85°C temperature range are mandatory. The PQFP package supports visual solder joint inspection and simplifies prototyping and production fixturing. As an active product in Microchip’s long-lifecycle portfolio, the A3P250-PQG208I presents minimal obsolescence risk for extended program lifetimes. Procurement considerations center on its single-chip, non-volatile architecture that reduces board complexity and enhances reliability in space-constrained, high-reliability designs.
