A54SX32A-FG144I

Overview

The A54SX32A-FG144I is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic performance with internal clock frequencies up to 350 MHz. The device supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V levels. It is housed in a 144-pin Fine Pitch Ball Grid Array (FG) package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for predictable signal propagation times.
• Features IEEE 1149.1 compliant Boundary-Scan Testing capabilities with flexible or dedicated JTAG pin configurations.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Industrial applications necessitating operation across extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with Actel Designer software versions supporting the SX-A architecture. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve.

Selection Notes

Select this component when design complexity requires approximately 48,000 system gates and high-speed internal processing. Consider the FG package dimensions for PCB layout constraints. Evaluate the need for industrial temperature ratings versus commercial options based on environmental operating conditions.

Part Context

This part belongs to the Actel SX-A FPGA family, which bridges the gap between CPLDs and gate arrays. The SX-A series is characterized by its antifuse-based nonvolatile fabric and optimized 'sea-of-modules' architecture designed for cost-effective, high-density logic implementations.

Replacement Considerations

Consult official Microchip cross-reference guides for verified substitutes. Verify that alternative devices maintain compatible pin counts, logic capacities, and package footprints to ensure mechanical and electrical interchangeability.
