A54SX16A-1FG144

Overview

The A54SX16A-1FG144 is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with a -1 speed grade for approximately 15% faster performance than standard. The device operates at 2.5 V core voltage and supports mixed-voltage I/Os (2.5 V, 3.3 V, 5 V). It is housed in a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Deterministic timing with up to 100% resource utilization and 100% pin locking capability
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and full pin-locking for concurrent PCB development
• Applications needing hot-swappable interface capabilities without power sequencing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the FBGA package dimensions match the design footprint. Check for discontinuation notices as older speed grades may have limited availability.

Selection Notes

Select this part for designs requiring 24,000 system gates with fast internal routing. The -1 speed grade offers improved performance over the standard version. Ensure the application supports the 2.5 V core voltage and compatible I/O standards. Verify thermal requirements for the FBGA package.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their high-density antifuse technology. The SX-A series provides a cost-effective platform for low-power, high-performance designs. The A54SX16A variant sits between the smaller A54SX08A and larger A54SX32A devices in terms of logic capacity.

Replacement Considerations

Direct replacements within the same package include other speed grades of the A54SX16A such as the standard or -2 variants. Cross-family replacements like the ProASIC3 series require verification of pin compatibility and logic architecture differences.
