A54SX08-TQG144I

Overview

The Microsemi A54SX08A-TQG144I is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It provides 12,000 system gates and 768 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features deterministic timing with internal clock frequencies reaching 350 MHz and system performance at 250 MHz. The component is rated for industrial temperature ranges (-40°C to +85°C).

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing.
• Includes Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1.

Applications

• High-performance digital logic integration requiring deterministic timing.
• Systems requiring hot-swappable interface capabilities.
• Applications needing secure programming to prevent reverse engineering via FuseLock technology.

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options may vary. Ensure design compatibility with the SX-A family architecture before procurement.

Selection Notes

Select this model for designs requiring 12,000 system gates with a 144-pin footprint. Verify that the required I/O voltage levels match the supported 2.5 V, 3.3 V, or 5 V configurations. Consider the -1 speed grade if faster performance than standard is needed.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs. It utilizes antifuse technology rather than SRAM-based configuration, providing permanent programming. The SX-A series is designed for low-power, high-density applications replacing complex CPLDs or gate arrays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other devices in the A54SX08A series or higher capacity SX-A models if pin counts or resource requirements differ.
