A54SX32A-1TQG144I

Overview

The A54SX32A-1TQG144I is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. Key specifications include up to 113 user-programmable I/Os, three global clock networks, and compliance with IEEE 1149.1 Boundary-Scan Testing.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing performance enabled by metal-to-metal programmable interconnect elements
• Integrated security features via FuseLock technology to prevent reverse engineering

Applications

• Industrial control systems requiring deterministic logic processing
• Mixed-voltage interface bridging between 2.5 V, 3.3 V, and 5 V components
• High-speed data path logic and state machine implementations
• Boundary-Scan testing environments for board-level diagnostics

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as packaging options may vary. Ensure design files account for the TQFP pinout and thermal characteristics specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a nonvolatile FPGA solution with mixed-voltage I/O support is required. The SX-A architecture offers high resource utilization and predictable timing suitable for complex logic designs. Consider the 144-pin TQFP package constraints regarding pin count and physical footprint during PCB layout planning.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family provides a single-chip solution for low-power, high-performance applications, integrating logic resources with robust I/O capabilities and secure programming features.

Replacement Considerations

Direct replacements within the same package and speed grade should be sought from the A54SX32A series. Verify that alternative devices maintain compatibility with the 144-pin TQFP form factor and meet the specific industrial temperature requirements.
