A54SX16A-2FG144I

Overview

The A54SX16A-2FG144I 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 24,000 system gates and 1,452 logic modules within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at an industrial temperature range of -40°C to +85°C and supports up to 111 user-programmable I/O pins. It delivers 250 MHz system 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.
• Hot-swap compliant I/Os that tristate during power-up/down without requiring supply voltage sequencing.
• Configurable I/O support for mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring hot-swappable interface capabilities without host system degradation
• Designs needing secure programming with reverse engineering protection via FuseLock technology

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the FBGA-144 configuration. Confirm availability status as older speed grades may be discontinued.

Selection Notes

Select this component when 24,000 system gates and 111 user I/Os are required in a compact 144-pin FBGA form factor. The Industrial temperature grade (-40°C to +85°C) suits environments exceeding commercial limits. Verify that the 250 MHz system performance meets the design's timing constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for nonvolatile configuration. The SX-A series offers high-density logic blocks and dedicated clock networks, designed for applications demanding deterministic timing and robust security features against unauthorized access.

Replacement Considerations

Check for discontinued status of the –2 speed grade. Consult the manufacturer's discontinuance notifications for valid cross-references or updated part numbers within the SX-A portfolio.
