A54SX08-1TQG144I

Overview

The Microsemi A54SX08-1TQG144I is an antifuse-based Field Programmable Gate Array from the SX-A family. It provides 12,000 system gates and 768 logic modules (CLBs). The device supports up to 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. It operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. Electrical specifications include a supply voltage range of 2.5 V to 5.0 V, supporting mixed-voltage operation with 5 V input tolerance. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources to minimize signal propagation delays.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Industrial control systems requiring deterministic timing and mixed-voltage I/O interfaces.
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options may vary. Ensure design compatibility with the SX-A family programming tools and verify that the TQFP144 footprint matches the target PCB layout requirements prior to procurement.

Selection Notes

Select this component when a nonvolatile FPGA with high-speed deterministic performance is required. The -1 speed grade offers approximately 15% faster performance than the standard grade. Ensure the design utilizes the available 768 CLBs and 113 I/Os efficiently. Verify that the 2.5V to 5.0V operating voltage range aligns with the system power supplies and that the Industrial temperature grade meets environmental constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS process technology. The SX-A series is known for its high-density antifuse architecture, offering significant system gate counts ranging from 12,000 to 108,000. Microsemi Corporation acquired Actel, integrating these high-reliability devices into their broader portfolio of programmable solutions.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sought from the A54SX08A series. Cross-family migration to newer Microsemi FPGA architectures requires careful review of I/O standards, power management, and programming tool compatibility.
