A54SX32A-1FGG256

Overview

The A54SX32A-1FGG256 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 48,000 system gates and 2,880 logic modules. It supports up to 203 user I/Os within a 256-pin Fine Pitch Ball Grid Array package. The device operates at a maximum frequency of 263 MHz with a nominal supply voltage of 2.5 V, ranging from 2.25 V to 2.75 V. It includes three global clock networks and complies with IEEE 1149.1 boundary-scan testing standards.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for nonvolatile configuration without external memory requirements.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing constraints.
• Integrates dedicated routing resources including DirectConnect and FastConnect for deterministic signal propagation.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Industrial control systems requiring mixed-voltage interface capabilities
• Automotive electronics utilizing automotive temperature grade variants
• Boundary-scan testing and diagnostic verification environments

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm specific ordering suffixes match required speed grades, temperature ranges, and packaging specifications. Review current product lifecycle status as availability may be limited due to discontinuation notices. Ensure compliance with export regulations applicable to the destination region.

Selection Notes

Select this model when 48,000 system gates and 203 I/Os fit the design constraints. Choose the -1 speed grade for performance exceeding standard levels. Verify thermal requirements against commercial or industrial operating ranges. Consider pin count compatibility with the 256-FBGA footprint during PCB layout planning.

Part Context

This component belongs to the Actel SX-A FPGA family, characterized by antifuse-based architecture. It sits between the A54SX16A and A54SX72A in terms of logic capacity. The series emphasizes low power consumption and high-speed deterministic timing suitable for embedded applications.

Replacement Considerations

Direct functional substitutes within the same package and pinout are not explicitly listed in public documentation. Evaluate other SX-A family members like A54SX32A-FGG256 for pin-compatible alternatives if speed grades differ. Consult Microchip for updated portfolio recommendations regarding end-of-life transitions.
