A54SX72A-PQG208I

The Microchip A54SX72A-PQG208I is a radiation-tolerant field-programmable gate array (FPGA) from the SX-A family, supplied in a 208-pin plastic quad flat pack (PQFP) with an industrial temperature rating. Based on antifuse technology, this single-chip device provides inherent single-event upset (SEU) immunity and latch-up protection without requiring external configuration memory, enabling live power-up operation and high functional reliability in demanding environments. The architecture delivers predictable timing closure and low standby current, with hardened registers and routing resources designed to meet the tolerance requirements of space-constrained terrestrial and orbital systems.

Typical applications span satellite payloads, launch vehicle avionics, defense electronics, and high-reliability industrial control systems where deterministic performance and radiation hardness are mandatory. Procurement professionals should note the industrial grade indicated by the “I” suffix, making the device suitable for extended temperature ranges without the cost and export controls of full military screening. As a Microchip product inherited from Actel and Microsemi, the SX-A family occupies a mature lifecycle position, and availability may depend on authorized distribution channels and factory lead times. Long program lifespans in aerospace and defense sectors benefit from this part’s stable design, but obsolescence planning is recommended when qualifying it for new designs.
