A3P1000-1FG144I

The A3P1000-1FG144I is a ProASIC3 flash-based field-programmable gate array (FPGA) from Microchip Technology, offering 1 million system gates in a 144-ball fine-pitch ball grid array (FBGA) package, rated for industrial temperature operation and a -1 speed grade. Its non-volatile flash configuration eliminates external boot memory, enabling instant-on capability at power-up and reducing bill-of-materials count. The flash architecture provides inherent immunity to configuration single-event upsets (SEU), a key advantage in high-reliability environments. The device operates on a 1.5 V core voltage with low static power, features flexible I/O banks supporting LVCMOS, LVTTL, and other standards, and includes embedded block RAM and phase-locked loops (PLLs) for clock management. In-system reprogrammability via JTAG, combined with Microchip’s FlashLock security, protects sensitive intellectual property.

Typical applications span industrial automation and motor control, secure communications interfaces, defense avionics, and high-reliability systems where fast boot, low power, and data retention are critical. The industrial temperature suffix (-I) confirms sustained performance over an extended temperature range, supporting deployment in harsh thermal conditions. From a procurement perspective, the single-chip flash FPGA simplifies supply chain management by removing dependency on separate configuration devices, thereby reducing BOM complexity and avoiding component obsolescence mismatches. The ProASIC3 family is a mature platform supported under Microchip’s long lifecycle program, minimizing redesign risk for sustained production programs; nonetheless, design teams should verify current lifecycle status and availability through authorized distribution for new design-ins.
