A54SX08A-2TQG100I

Overview

The A54SX08A-2TQG100I is an SX-A family FPGA featuring 12,000 system gates and 768 logic modules. It operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The device supports up to 81 user I/Os in a 100-pin TQFP package. It achieves a maximum operating frequency of 278 MHz and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Enables mixed-voltage operation with configurable support for 3.3 V, 5 V PCI, and 5 V TTL standards.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• High-performance digital signal processing requiring low-latency interconnects
• Industrial control systems necessitating hot-swappable interface capabilities
• Complex state machine implementations utilizing dedicated flip-flops

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm speed grade and temperature rating. Ensure compatibility with existing PCB footprints for the 100-TQFP package. Confirm that the design tool version supports the SX-A architecture for accurate place-and-route results.

Selection Notes

Select this component when 12,000 system gates are sufficient for the target logic density. Consider the -2 speed grade if higher performance than standard is required but lower than -3 grades. Verify that the 81 available I/O pins meet the interface requirements for the specific application design.

Part Context

This part belongs to the Actel SX-A family of antifuse FPGAs. It utilizes 0.22 μm / 0.25 μm CMOS technology. The series offers nonvolatile configuration, eliminating the need for external configuration memory devices during power-up.

Replacement Considerations

Check for A54SX08A-1TQG100I or A54SX08A-TQG100I variants. These share the same package and pinout but differ in speed grade or commercial temperature range specifications.
