A54SX16P-1VQ100

Overview

The A54SX16P-1VQ100 is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports a maximum internal clock frequency of 350 MHz and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high performance.
• Provides nonvolatile configuration via metal-to-metal antifuses to prevent reverse engineering.

Applications

• High-performance digital signal processing
• Interface bridging between different voltage domains
• Prototyping complex logic designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints and verify that the antifuse-based programming method aligns with your manufacturing workflow.

Selection Notes

Select this component when a nonvolatile FPGA solution with mixed-voltage I/O support is required. Consider the 24,000 gate capacity and 350 MHz internal performance for moderate complexity logic designs. Verify that the TQFP-100 package fits the available board space and thermal constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for permanent configuration. The SX-A series is designed for applications requiring low power consumption and high reliability, distinguishing it from volatile SRAM-based FPGAs that require external configuration memory.

Replacement Considerations

Direct pin-compatible replacements are not publicly confirmed in the provided documentation. Evaluate other devices within the SX-A family or newer Microchip FPGA families based on gate count, package dimensions, and I/O voltage compatibility.
