A54SX08-2TQG144

Overview

The Microsemi A54SX08-2TQG144 is a Field Programmable Gate Array from the SX-A family, featuring 12,000 system gates and 768 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic performance with up to 350 MHz internal clock speeds. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, offering 113 user-programmable I/O pins. It is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swappable I/O configurations for safe insertion into active systems without power sequencing requirements.
• Provides nonvolatile single-chip integration using metal-to-metal programmable antifuse interconnect elements.
• Includes IEEE 1149.1 compliant boundary-scan testing capabilities for enhanced diagnostic verification.

Applications

• Integration of 66 MHz PCI compliant logic functions
• High-performance state machine implementations
• Fast counter and data path logic designs

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm that the component matches the required speed grade and pin count specifications before finalizing procurement orders.

Selection Notes

Select this model when a compact 144-pin form factor is required alongside moderate logic density. Ensure the design leverages the device's mixed-voltage I/O capabilities if interfacing with legacy 5 V components or modern 3.3 V standards.

Part Context

This component belongs to the Actel SX-A FPGA family, which is characterized by its high-density antifuse architecture. The SX-A series provides a cost-effective alternative to gate arrays while maintaining high-speed performance through optimized routing resources like DirectConnect and FastConnect.
