Military-temperature ProASIC3 for harsh environments
The Microchip A3P250-VQ100M is a ProASIC3 FPGA with 250,000 gates and 68 user I/O in a 100-pin VQFP package.
Gate count, RAM, and I/O — what fits
250,000 system gates is a mid-density tier — enough for a state machine, a few SPI/I2C bridges, or a glue-logic consolidation that replaces a handful of 74-series parts. The 68 I/O count is the pin-limited constraint: if your design needs more than 68 signals, you step up to a larger package variant in the same family. On-chip RAM totals 36,864 bits, which covers small FIFOs or register files but not frame buffers or large data caches.
Single-rail core supply
The core operates from a 1.425 V supply — a single-rail architecture that simplifies the power tree compared to older FPGAs needing separate VCCINT and VCCIO rails. The I/O banks tolerate 3.3 V, so the supply design is straightforward: one 1.425 V regulator for the core, one 3.3 V rail for the I/O.
Active lifecycle — no LTB scramble
No last-time-buy notice, no end-of-life clock ticking.
RoHS compliance
The 'VQ' package suffix in the order code indicates a RoHS-compliant, lead-free finish. No separate Pb-free certification needed — the part number itself carries the compliance designation.
