A54SX08-1VQG100

Overview

The A54SX08-1VQG100 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microsemi Corporation. It features a capacity of 12,000 system gates and 768 logic modules. The device supports up to 81 user-programmable I/O pins and includes dedicated flip-flops for sequential logic implementation. Operating at speed grade -1, it delivers approximately 15% faster performance than standard speed grades, with internal clock frequencies reaching 350 MHz. It operates within a voltage range of 2.25 V to 5.25 V and is rated for industrial temperatures between -40°C and +85°C. The component is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Industrial control systems requiring deterministic timing and robust I/O configurations.
• Secure embedded designs utilizing FuseLock technology to prevent reverse engineering.

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options vary. Check current availability through authorized distributors, noting that older speed grades may have limited stock or discontinuation notices.

Selection Notes

Select this model when 12,000 system gates and 81 I/Os are sufficient for the design requirements. Ensure the application benefits from nonvolatile antifuse technology over volatile SRAM FPGAs. Verify that the 100-pin TQFP package fits the PCB layout constraints and that the -1 speed grade meets the maximum operating frequency needs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi. The SX-A series is characterized by its high-density antifuse architecture, offering low power consumption and high security compared to other programmable logic devices of its era.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX08A series. Consider upgrading to newer Microsemi FPGA families if modern fabrication processes or updated software tools are required for long-term production support.
