A54SX72A-FFGG484

Overview

The A54SX72A-FFGG484 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. The device supports up to 360 user-programmable I/O pins and operates with internal clock frequencies reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable I/O support for multiple standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Deterministic timing performance enabled by unique local routing resources such as DirectConnect and FastConnect.

Applications

• High-performance digital signal processing requiring deterministic timing.
• System integration replacing complex programmable logic devices (CPLDs).
• Applications requiring hot-swappable capabilities and power-up/down flexibility.

Procurement Notes

Verify the specific speed grade suffix associated with the part number, as standard speed variants exist alongside faster options. Confirm that the FBGA-484 package matches the target PCB footprint requirements. Ensure the design software supports the specific temperature grade indicated in the ordering code to guarantee operational limits are met.

Selection Notes

Select this device when high gate density and fast internal clock speeds are required. The SX-A architecture offers 100% pin-locking and resource utilization, facilitating concurrent PCB development. Consider the availability of quadrant clocks in the A54SX72A model for distributed clock network designs compared to smaller family members.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated on a high-voltage twin-well CMOS process. The family ranges from 12,000 to 108,000 system gates, providing a scalable platform for low-power, high-performance designs. The A54SX72A represents the highest capacity tier within this specific generation of antifuse-based FPGAs.
