A54SX08-VQ100I

The Microchip Technology A54SX08-VQ100I is an antifuse-based field-programmable gate array (FPGA) from the SX-A family, integrating 8,000 system gates of non-volatile logic into a 100-pin VQFP package qualified for industrial environments. Built on one-time programmable antifuse technology, the device delivers instant-on capability, low dynamic power dissipation, and inherent immunity to radiation-induced configuration errors. Unlike SRAM-based FPGAs, it eliminates the need for external boot memory, reducing board complexity and protecting against bitstream interception or tampering. The –I suffix designates a reliable operating range of -40°C to +85°C, and the compact VQFP footprint supports space-constrained designs where high shock and vibration tolerance are priorities.

This part is regularly specified in avionics instrumentation, secure tactical communication nodes, industrial motor drives, and high-reliability embedded controllers that demand deterministic power-up behavior and long service life. For procurement and engineering teams, the SX-A family remains an active Microchip offering following the Actel/Microsemi acquisition, yet antifuse FPGAs occupy a mature, niche segment; lead times can extend and future obsolescence planning is advisable. The industrial temperature rating bridges the gap between commercial and full military screening, providing a cost-effective choice for rugged systems that do not require MIL-STD-883 qualification but must tolerate extended thermal stress and maintenance-free operation.
