A54SX32A-1FG144M

Overview

The A54SX32A-1FG144M is a Field Programmable Gate Array from the Microsemi SX-A family, utilizing 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 111 user-programmable I/O pins within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. It features a maximum internal clock frequency of 350 MHz and operates at a nominal voltage of 2.5 V, with support for mixed-voltage I/O standards including 3.3 V and 5 V. The -1 speed grade offers approximately 15% faster performance than standard, while the 'M' suffix indicates military temperature range operation (-55°C to +125°C).

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements.
• Includes Silicon Explorer II for unique in-system diagnostic and verification capabilities.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• High-performance digital signal processing requiring deterministic timing.
• Military and aerospace systems necessitating extended temperature ranges.
• Complex state machine implementations utilizing fast local routing resources.
• PCI-compliant interface designs supporting 66 MHz operations.

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Ensure that the military grade designation aligns with project environmental requirements. Confirm RoHS compliance status if applicable to the manufacturing process. Check for any product discontinuation notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when high-density logic is required alongside strict timing predictability. The antifuse architecture ensures permanent configuration without external memory. Consider the -1 speed grade for applications needing improved performance over standard grades. Verify that the 144-pin FBGA package fits the available PCB real estate and thermal constraints for the target environment.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for low-power, high-performance applications. The family utilizes a sea-of-modules architecture with dedicated DirectConnect and FastConnect routing resources to minimize propagation delays. The SX-A series bridges the gap between CPLDs and larger FPGAs, offering full pin-locking capabilities and 100% resource utilization.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as the standard A54SX32A-FG144 or the faster A54SX32A-2FG144. For broader compatibility, consider devices from the subsequent SmartFusion or IGLOO families, though architectural differences require design re-evaluation.
