A3P250-VQG100I

The A3P250-VQG100I is a Flash-based field-programmable gate array (FPGA) from Microchip Technology, part of the ProASIC3 nano family optimized for low-power, high-reliability embedded systems. This device delivers 3,000 logic elements (3K LEs) and 36 Kbits of embedded SRAM in a compact 100-pin VQFP package, with up to 68 user I/Os available depending on configuration. Its non-volatile flash configuration eliminates the need for external boot memory, enabling instant-on operation and reducing board-level component count. The single-chip architecture also provides inherent immunity to configuration bit flips induced by radiation or noisy environments, making it inherently more rugged than SRAM-based alternatives. The industrial temperature range (–40°C to +85°C) indicated by the “I” suffix suits harsh-environment deployments, while the fine-pitch 0.5 mm VQFP package supports space-constrained designs.

Typical applications span industrial control, motor drives, sensor interface bridging, and secure embedded processing where low static power and small footprint are critical. In aerospace and defense systems, the device is used for glue logic, protocol adaptation, and cryptographic co-processing, benefiting from its live-at-power-up behavior and resistance to single-event upsets. Design engineers often select this FPGA for medical instrumentation, automotive test equipment, and edge computing nodes that require deterministic start-up and long-term availability. From a procurement perspective, Microchip’s ProASIC3 nano family maintains a stable product lifecycle with minimal obsolescence risk, supported by extended-temperature options and documented reliability data suited for high-reliability programs. The flash-based fabric also reduces supply-chain complexity by removing separate configuration devices, which can be a critical advantage in long-life industrial and mil-aero systems.
