A54SX32A-FGG144M

Overview

The A54SX32A-FGG144M is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device features up to 1,980 dedicated flip-flops and supports up to 111 user-programmable I/O pins within a 144-pin Fine Pitch Ball Grid Array package. It operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. The component supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V supplies and includes three global clock networks.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and direct routing resources.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Low-power designs requiring mixed-voltage I/O integration

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm military temperature grade availability (-55°C to +125°C) and MIL-STD-883 Class B compliance. Ensure the ordering information matches the exact pin count and package type specified in the datasheet before procurement.

Selection Notes

Select this model for applications requiring high-density logic with deterministic timing characteristics. Consider the 144-pin FBGA package constraints and verify that the 111 available user I/Os meet interface requirements. Confirm that the 250 MHz system speed grade satisfies the target application's timing closure needs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes nonvolatile antifuse technology. The family ranges from 12,000 to 108,000 system gates. The A54SX32A variant specifically targets mid-range complexity designs, offering a balance between logic capacity and pin count for versatile embedded applications.

Replacement Considerations
