A54SX32A-1BG329M

Overview

The A54SX32A-1BG329M is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2880 logic modules. It operates at a maximum frequency of 278 MHz with a 2.5 V supply voltage range of 2.25 V to 2.75 V. The device utilizes a 329-pin Plastic Ball Grid Array (PBGA) package and supports up to 249 user-programmable I/Os. Designed for military applications, it functions within a temperature range of -55°C to +125°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• Military aerospace systems requiring extended temperature operation
• High-performance digital signal processing implementations
• Secure hardware designs utilizing antifuse technology for IP protection
• Complex state machine and data path logic integration

Procurement Notes

Verify the specific ordering suffix 'M' corresponds to the military temperature grade (-55°C to +125°C) as defined in the official Actel/Microchip SX-A datasheet. Confirm that the PBGA329 package dimensions match the target PCB footprint requirements. Ensure design tools support the specific speed grade indicated by the '-1' suffix for accurate timing closure.

Selection Notes

Select this component when military-grade environmental resilience is required alongside high-density logic capacity. The SX-A family offers deterministic performance suitable for complex parallel processing tasks. Consider the nonvolatile nature of the antifuse technology if system boot time and configuration security are critical constraints compared to volatile FPGA alternatives.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which transitioned to Microchip Technology following corporate acquisitions. The SX-A series is characterized by its use of metal-to-metal antifuse programming technology, distinguishing it from SRAM-based FPGAs. This specific model represents the mid-range density option within the family, balancing gate count with pin availability.

Replacement Considerations

Direct replacements include other speed grades within the A54SX32A series such as A54SX32A-FG256 or A54SX32A-FFGG144, provided the package and pinout compatibility are verified. Industrial grade variants like A54SX32A-I may be considered if military specifications are not strictly required.
