A54SX32A-FG144M

Overview

The A54SX32A-FG144M is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2880 logic modules. It operates within a voltage range of 2.25 V to 2.75 V for core supply and supports mixed-voltage I/O standards including 3.3 V and 5 V tolerance. The device utilizes a 144-pin Fine Pitch Ball Grid Array (FG) package with 111 user-programmable I/Os. Designed for military applications, it supports an operating temperature range of -55°C to +125°C and incorporates nonvolatile antifuse technology.

Feature Summary

• Military-grade reliability with extended temperature coverage
• Nonvolatile antifuse architecture ensuring permanent configuration
• Hot-swap compliant I/Os allowing safe insertion into active systems
• Deterministic timing through metal-to-metal programmable interconnect

Applications

• Military avionics and defense electronics
• Spacecraft embedded control systems
• Harsh environment industrial automation controllers

Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the required military temperature grade (-55°C to +125°C). Confirm that the FG144 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives if applicable to the assembly process. Check for any end-of-life notifications or production discontinuation status prior to finalizing procurement plans.

Selection Notes

Select this component when high-density logic is required in a compact 144-pin form factor. The military temperature rating makes it suitable for extreme environments where commercial or industrial grades fail. Consider the 48K gate capacity against design complexity requirements. Verify that the 111 available I/O pins meet the interface count needs of the target application.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is known for its sea-of-modules architecture and deterministic performance. The 'A' suffix typically denotes an enhanced version of the original SX-A line, offering improved speed grades and features while maintaining pin compatibility.

Replacement Considerations

Direct replacements within the same package and pinout include other A54SX32A variants with different speed grades or temperature ratings, such as A54SX32A-1FG144M or A54SX32A-2FG144M. Cross-family migration to newer Microchip Actel ProASIC3 or PolarFire devices requires significant schematic and layout redesign due to architectural differences.
