A54SX72A-2FG484I

Overview

The A54SX72A-2FG484I is an industrial-grade Field Programmable Gate Array from the SX-A family, featuring 108,000 system gates and 6,036 logic modules. It utilizes a 0.22 μm / 0.25 μm CMOS antifuse process with a maximum internal performance of 350 MHz. The device supports up to 360 user I/Os in a 484-pin Fine Pitch Ball Grid Array (FBGA) package. Key specifications include three global clock networks and four quadrant clocks, mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os, and compliance with IEEE 1149.1 Boundary-Scan Testing.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• High-performance routing architecture incorporating DirectConnect and FastConnect resources to minimize signal propagation delays.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Integrated security features including FuseLock technology to prevent reverse engineering and unauthorized design access.

Applications

• Complex digital logic integration replacing multiple CPLDs or gate arrays
• Industrial control systems requiring deterministic timing and high reliability
• Prototyping designs targeting ASIC implementation using antifuse technology

Procurement Notes

Verify the specific speed grade suffix associated with the -2 designation against current manufacturer documentation, as historical data indicates discontinuation of certain grades. Confirm that the FBGA-484 package availability aligns with current production lifecycles. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture prior to ordering.

Selection Notes

Select this component when designing systems requiring nonvolatile FPGA configuration without external boot devices. The -2 speed grade offers approximately 25% faster performance than standard speed variants. Consider the 484-pin package constraints for PCB layout and ensure thermal management meets the industrial temperature range requirements of -40°C to +85°C.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse-based nonvolatile fabric. The A54SX72A represents the highest capacity device within this specific series, offering 108,000 system gates. The family is known for its high-speed routing and secure, single-chip implementation capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Microchip Technology for current equivalent offerings within the PolarFire or IGLOO2 families if SX-A availability is limited.
