A54SX32A-1CQ256M

Overview

The A54SX32A-1CQ256M is a military-grade Field Programmable Gate Array from the HiRel SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and supports up to 228 user-programmable I/O pins within a 256-pin Ceramic Quad Flat Pack (CQFP) package. The device operates at a standard supply voltage of 2.5 V with a range of 2.25 V to 2.75 V. It delivers a maximum system performance frequency of 215 MHz and an internal clock speed of 240 MHz under military temperature conditions (-55°C to +125°C). The architecture utilizes nonvolatile antifuse technology for deterministic timing and low power consumption.

Feature Summary

• Military-grade reliability compliant with MIL-STD-883 Class B standards and QML certification.
• Nonvolatile antifuse architecture providing permanent configuration without bitstream requirements.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.

Applications

• High-reliability military avionics and defense electronics
• Spacecraft and satellite communication subsystems
• Harsh environment industrial control systems requiring radiation tolerance

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm that the specific ordering suffix matches the required speed grade and package variant. Ensure compliance with export regulations such as ITAR or EAR if applicable to the destination region. Request full traceability documentation including lot history and test reports.

Selection Notes

Select this model when high-density logic integration is required in a hermetic ceramic package suitable for extreme temperatures. The -1 speed grade offers approximately 15% faster performance than the standard version. Consider the 256-pin CQFP footprint constraints during PCB layout. Verify that the design does not require SRAM-based reconfiguration capabilities.

Part Context

This part belongs to the Actel HiRel SX-A family of FPGAs, which are designed for high-reliability applications. The A54SX32A designation indicates 48,000 system gates. The '1' suffix denotes the faster speed grade, while 'CQ256' specifies the 256-pin ceramic quad flat pack package. The 'M' suffix confirms military temperature rating.

Replacement Considerations

Direct pin-compatible replacements within the same family include other A54SX32A variants with different speed grades or packages. For higher capacity needs, the A54SX72A series serves as a scalable alternative. Cross-family migration to newer Microchip FPGA lines requires architectural redesign.
