A3P1000-1FG256T

The Microchip Technology A3P1000-1FG256T is a flash-based ProASIC3 field-programmable gate array (FPGA) providing one million system gates in a 256-ball fine-pitch ball grid array (FBGA) package. Its non-volatile flash configuration cells eliminate external boot memory, delivering true single-chip, live-at-power-up operation with instantaneous wake-up and minimal static power draw. The flash architecture also offers superior immunity to configuration bit-flips compared to SRAM-based alternatives, and the device supports in-system reprogrammability for field updates. The -1 speed grade provides balanced performance, while the T suffix denotes an extended operating temperature range of −55°C to +125°C, ensuring reliable logic operation in harsh thermal environments.

This FPGA is designed into defense avionics, missile guidance seekers, secure communications infrastructure, and other mission-critical systems where instant-on capability and configuration integrity are non-negotiable. Industrial applications include high-temperature motor drives, distributed automation controllers, and downhole drilling tools exposed to wide thermal swings. Medical imaging platforms and rugged aerospace payloads also leverage the device’s deterministic timing and low power. From a procurement standpoint, the ProASIC3 family eliminates external configuration memory from the bill of materials, simplifying supply chain management and reducing board area. Microchip’s long-term continuity program and the part’s extended-temperature grade support extended product life cycles, mitigating obsolescence risk in defense and industrial programs that demand sustained availability over two decades.
