A54SX72A-1CQ256M

Overview

The A54SX72A-1CQ256M is a high-reliability Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and supports up to 213 user-programmable I/O pins within a 256-pin Ceramic Quad Flat Pack (CQFP) package. The device operates at a maximum frequency of 215 MHz with a clock-to-out delay of 5.3 ns under military temperature conditions. It utilizes a 0.25/0.22 µ CMOS process technology and supports mixed voltage operation ranging from 2.5 V to 5 V. The component is qualified for MIL-STD-883 Class B standards and undergoes 100% testing across the full military temperature range of –55°C to +125°C.

Feature Summary

• Nonvolatile antifuse architecture providing deterministic timing and inherent design security against reverse engineering.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE 1149.1 for in-system verification.
• Configurable logic modules including DirectConnect and FastConnect routing for optimized signal propagation.

Applications

• Military avionics and defense electronics requiring radiation tolerance and high reliability.
• Space-grade instrumentation and satellite communication subsystems.
• Industrial control systems operating in extreme environmental conditions.
• Secure hardware implementations utilizing FuseLock™ technology.

Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and package configuration. Confirm compliance with current export control regulations, as these components may be subject to ITAR or EAR restrictions. Ensure that the procurement channel provides valid traceability documentation consistent with MIL-STD-883 Class B quality requirements.

Selection Notes

Select this model when high-density logic integration is required alongside strict military temperature specifications. The 256-pin CQFP package is suitable for applications demanding robust mechanical stability and thermal performance. Consider the available quadrant clocks if complex global clock distribution networks are necessary for the design architecture.

Part Context

This component belongs to the Actel HiRel SX-A family, which bridges commercial FPGA capabilities with military-grade reliability standards. The SX-A series is characterized by its antifuse-based nonvolatile memory, distinguishing it from SRAM-based FPGAs. This family serves as a foundational platform for high-performance programmable logic in sectors where data retention and resistance to environmental stressors are critical operational parameters.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX72A series. Verify that any substitute maintains the same MIL-STD-883 Class B qualification level and hermetic sealing characteristics to ensure continued compliance with high-reliability application requirements.
