A54SX16-1TQG176I

Overview

The A54SX16-1TQG176I is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The device operates at a maximum system frequency of 250 MHz with internal performance up to 350 MHz. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 I/O standards with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated clock networks comprising one hardwired HCLK and two global routed clocks for deterministic timing.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions.
• Systems requiring hot-swappable interface capabilities without supply voltage sequencing.
• Industrial applications necessitating operation across extended temperature ranges.

Procurement Notes

Verify the specific ordering suffix against current Microchip documentation to confirm package type and temperature grade. Confirm availability status as older speed grades may be discontinued. Ensure design tools support the SX-A architecture for proper configuration.

Selection Notes

Select this model for designs requiring approximately 24,000 system gates within a 176-pin footprint. Consider the -1 speed grade for performance exceeding standard specifications. Verify I/O voltage requirements match the supported 2.5 V, 3.3 V, or 5 V configurations.

Part Context

This component belongs to the Actel SX-A FPGA family, characterized by metal-to-metal programmable antifuse interconnects. The family offers high-density logic modules arranged in clusters to optimize silicon utilization and routing efficiency for complex digital designs.

Replacement Considerations

Check for updated speed grades or package options within the A54SX16A series. Consult Microchip discontinuation notices for legacy variants. Verify pin compatibility if substituting with other TQFP packages in the same gate count category.
