A54SX72A-1CQ208M

Overview

The A54SX72A-1CQ208M is a military-grade Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 208-pin Ceramic Quad Flat Pack (CQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It achieves a maximum internal clock frequency of 240 MHz and a pin-to-pin clock-to-out delay of 5.3 ns in the military temperature range of –55°C to +125°C. The architecture utilizes metal-to-metal antifuse technology for nonvolatile configuration.

Feature Summary

• Military-grade reliability with QML certification and MIL-STD-883 Class B compliance
• Nonvolatile antifuse architecture providing deterministic timing and design security
• Hot-swap compliant I/Os supporting cold-sparing applications without voltage sequencing
• Configurable I/O standards including 3.3 V/5 V PCI, LVTTL, and TTL

Applications

• High-reliability military avionics systems
• Spacecraft embedded processing units
• Defense communication infrastructure
• Harsh environment industrial control systems

Procurement Notes

Verify that the component matches the specific military grade requirements, as standard commercial variants lack the rigorous screening processes. Confirm the presence of QML certification documentation and MIL-STD-883 test reports. Ensure the ordering suffix corresponds to the correct package type and temperature rating. Check for any relevant export control classifications or ITAR restrictions applicable to high-reliability semiconductor devices.

Selection Notes

Select this model when nonvolatile configuration and radiation tolerance are not required but high reliability is critical. Compare against the standard SX-A family if cost reduction is prioritized over military qualification. Consider the 208-pin CQFP package constraints regarding board space and thermal management. Evaluate the 108,000 gate capacity against design complexity to ensure optimal resource utilization without excessive overhead.

Part Context

This part belongs to the HiRel SX-A family, which bridges the gap between commercial FPGAs and fully radiation-tolerant RadTolerant designs. It shares pin compatibility with commercial counterparts, facilitating prototyping. The family utilizes Actel's proprietary antifuse technology, distinguishing it from SRAM-based competitors. It serves as a robust solution for applications demanding long-term stability and immunity to single-event upsets in non-space environments.

Replacement Considerations

Direct replacements include other HiRel SX-A variants such as the A54SX32A-1CQ208M for lower density needs. Verify pinout compatibility before substituting with different package counts. Cross-reference with current Microchip FPGA portfolios for modern alternatives if legacy support becomes unavailable.
