A54SX72A-FG484

Overview

The A54SX72A-FG484 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 108,000 system gates and supports up to 360 user-programmable I/O pins within a 484-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. The device features 6,036 logic modules, including dedicated flip-flops, and operates at system performance speeds of 250 MHz with internal clock frequencies reaching 350 MHz. It supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os.

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 weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Support for multiple temperature grades including Commercial, Industrial, Automotive, and Military specifications.

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI-compliant interface designs supporting 66 MHz PCI standards
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering

Procurement Notes

Verify the specific speed grade suffix associated with the FG484 package, as standard speed variants exist alongside faster options. Confirm that the ordering suffix aligns with the required temperature range, such as Industrial or Military, to ensure compliance with environmental operating conditions. Cross-reference the datasheet revision to confirm pinout definitions remain consistent with current design requirements.
