A54SX72A-FFG484

Overview

The A54SX72A-FFG484 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 484-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. The device supports up to 360 user-programmable I/O pins and operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology. It provides deterministic timing performance with internal clock frequencies reaching 350 MHz.

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 configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up.
• Features individual output slew rate control and mixed-voltage operation support.

Applications

• High-performance digital signal processing systems
• Industrial automation and control logic
• Communication interface protocols

Procurement Notes

Verify the specific speed grade suffix associated with the FFG484 package, as standard speed variants exist alongside faster options. Confirm that the ordering suffix indicates RoHS compliance if environmental regulations require it. Ensure the temperature grade matches the operational environment requirements before finalizing procurement orders.

Selection Notes

Select this component when high gate density and deterministic timing are required for complex logic designs. The SX-A architecture offers optimal register-to-logic mixing suitable for state machines and data path applications. Consider the available global and quadrant clock resources for synchronous design implementations requiring precise timing constraints.

Part Context

This part belongs to the Actel SX-A FPGA family, which was acquired by Microchip Technology. The SX-A series is characterized by its antifuse technology, providing nonvolatile configuration without external memory. The A54SX72A represents the highest capacity device in the standard SX-A lineup, offering significant logic resources for demanding applications.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A such as A54SX72A-FGG484 or A54SX72A-1FGG484. Cross-family migration to newer Microchip FPGA architectures may be necessary for long-term supply assurance, though pin compatibility will differ.
