A54SX08-1PL84

Overview

The Microsemi A54SX08-1PL84 is an SX-A family Field Programmable Gate Array featuring 12,000 system gates and 768 logic modules. It utilizes a 0.22 μm / 0.25 μm CMOS antifuse process technology. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It provides up to 69 user-programmable I/O pins and includes three global clock networks. The component operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Low-power, high-performance embedded logic designs
• System integration replacing multiple complex programmable logic devices (CPLDs)
• Applications requiring nonvolatile single-chip solutions

Procurement Notes

Verify the specific package type against the datasheet, as PL84 indicates an 84-pin PLCC package which may have limited availability compared to standard PQFP or TQFP options. Confirm that the -1 speed grade meets the required system performance specifications before procurement.

Selection Notes

Select this model for applications requiring 12,000 system gates with mixed 3.3 V and 5 V I/O capabilities. Ensure the design fits within the 768 logic module capacity and verify that the 69 available user I/Os are sufficient for the interface requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, fabricated on a high-voltage twin-well CMOS process. The SX-A series is designed for cost-effective, low-power implementations using metal-to-metal programmable antifuse interconnect elements for permanent configuration.

Replacement Considerations

Consider the A54SX08A-1PQ208I for higher pin counts or the A54SX08A-1TQG100I for smaller surface-mount packages. Verify compatibility with existing PCB footprints when selecting alternative packages from the same device family.
