A54SX08-2TQG144I

Overview

The A54SX08-2TQG144I is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. 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 at an industrial temperature range of -40°C to +85°C. It features a speed grade of -2, delivering approximately 25% faster performance than standard speed grades, with internal clock frequencies reaching 350 MHz.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.
• Features Actel FuseLock security technology to prevent reverse engineering and unauthorized reading of design contents.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Applications needing secure, nonvolatile programmable logic

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing board layouts regarding the TQFP-144 footprint and pin assignments. Confirm that the selected speed grade meets the required system timing constraints.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed performance is required. The -2 speed grade offers improved timing over standard devices. Verify that the 113 available I/Os and 768 logic modules satisfy the design capacity needs. Consider the industrial temperature range suitability for the operating environment.

Part Context

This part belongs to the Microsemi SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS process technology. The family is known for its sea-of-modules architecture and high-density interconnect capabilities, targeting applications in communications, industrial control, and military systems.

Replacement Considerations

Check for other speed grades within the A54SX08A series if timing requirements differ. Verify package availability for alternative pin counts if I/O expansion is needed. Consult official substitution lists for any discontinued variants within the SX-A family.
