A54SX16A-FFGG144

Overview

The A54SX16A-FFGG144 is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and contains 1,452 logic modules (combinatorial cells). The device supports up to 111 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates with internal clock frequencies up to 350 MHz and delivers 250 MHz system performance. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os that tristate during power-up/down without requiring supply voltage sequencing.
• Includes deterministic timing capabilities with individual output slew rate control and configurable weak-resistor pull-ups or pull-downs.

Applications

• High-performance digital logic integration replacing complex CPLDs
• PCI-compliant interface designs supporting 66 MHz PCI standards
• Systems requiring secure programming with reverse-engineering protection via FuseLock technology

Procurement Notes

Verify the specific speed grade suffix associated with the FFGG144 package variant, as standard speed grades differ from faster variants. Confirm RoHS compliance status through official Microchip documentation, noting that ordering suffixes may indicate packaging variations. Ensure the source document explicitly lists this exact part number configuration before finalizing procurement specifications.

Selection Notes

Select this device when 24,000 system gates and 1,452 logic modules are required within a 144-pin footprint. Consider the FBGA package for fine-pitch surface-mount applications. Evaluate the -F speed grade if slower performance than standard is acceptable, or verify availability of other speed grades for the FG144 package. Check temperature grade requirements against the Commercial offering.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology rather than volatile SRAM configuration. The SX-A architecture features a sea-of-modules design with DirectConnect and FastConnect routing resources to minimize propagation delays. This family was originally developed by Actel Corporation before being acquired by Microsemi.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult Microchip's discontinuance notifications or product transition guides for legacy Actel FPGA replacements.
