A54SX08-2PL84I

Overview

The Microsemi A54SX08-2PL84I is an antifuse-based Field Programmable Gate Array (FPGA) belonging to the SX-A family. It features a capacity of 12,000 system gates and 768 logic modules. The device supports up to 130 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates within a voltage range of 2.25V to 5.25V and supports mixed-voltage I/O standards including 3.3V, 5V, and 2.5V. The -2 speed grade indicates performance approximately 25% faster than the standard speed variant. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing architecture with DirectConnect and FastConnect routing resources ensuring predictable signal propagation delays.
• Integrated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic and verification purposes.

Applications

• High-reliability industrial control systems requiring deterministic performance and nonvolatile configuration.
• Space and defense electronics benefiting from radiation tolerance and secure antifuse architecture.
• Prototyping complex logic functions previously implemented in gate arrays or multiple CPLDs.
• Systems requiring hot-swappable interface capabilities and mixed-voltage I/O compatibility.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check for End-of-Life notifications or Product Change Notices regarding availability. Ensure design tools support the SX-A family architecture for programming and verification.

Selection Notes

Select this model when 12,000 system gates are sufficient for the design logic requirements. Choose the -2 speed grade if higher internal clock frequencies are needed compared to standard grades. Verify that the 208-pin PQFP package fits the PCB footprint constraints. Ensure the application environment falls within the specified commercial or industrial temperature ranges supported by the package variant.

Part Context

This component is part of the Actel/Microsemi SX-A family of FPGAs, which utilizes antifuse technology for nonvolatile configuration. The family offers various capacities ranging from 8,000 to 108,000 system gates. The A54SX08 represents the entry-level capacity in this series, providing a cost-effective solution for mid-range logic applications with high reliability and security features inherent to antifuse devices.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX08A series. Consider upgrading to higher capacity devices like A54SX16A if additional logic resources are required, provided pin counts remain compatible. Verify that alternative packages (e.g., TQFP, PBGA) maintain the necessary I/O count for the specific application design.
