A54SX16A-FGG144I

Overview

The A54SX16A-FGG144I is an industrial-grade Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 logic modules. It utilizes a 0.22 μm / 0.25 μm CMOS antifuse technology to provide a nonvolatile, single-chip solution with deterministic timing. The device supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V levels, ensuring compatibility with various interface standards including PCI and TTL. Operating within an industrial temperature range of -40°C to +85°C, it is housed in a 144-pin Fine Pitch Ball Grid Array (FGG) package with a 1.0 mm pitch.

Feature Summary

• Nonvolatile antifuse architecture eliminates configuration bitstreams and prevents reverse engineering through FuseLock security features.
• Hot-swap compliant I/Os allow safe insertion into active systems without power sequencing requirements for supply voltages.
• Deterministic performance achieved via patented metal-to-metal interconnects and dedicated routing resources like DirectConnect and FastConnect.
• Supports IEEE 1149.1 Boundary-Scan Testing with flexible JTAG pin configurations for enhanced diagnostic capabilities.

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Embedded applications needing secure, nonvolatile programmable logic
• Systems requiring hot-swappable peripheral interfaces

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type corresponds to the 144-pin Fine Pitch Ball Grid Array (FGG) with a 1.0 mm pitch. Ensure the speed grade matches design timing requirements, as standard grades are available. Check for RoHS compliance status if environmental regulations apply to the deployment environment.

Selection Notes

Select this component when a nonvolatile FPGA solution is required to reduce system complexity and cost. The SX-A architecture is suitable for designs replacing multiple CPLDs or gate arrays where performance and pin-locking flexibility are critical. Consider the 144-pin FBGA package constraints for PCB layout and ensure thermal management aligns with the industrial operating range specifications provided in the datasheet.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX16A variant specifically offers 24,000 system gates and 1,452 CLBs. The SX-A series is known for its high-performance clock networks and robust security features inherent to antifuse-based architectures.

Replacement Considerations

Direct substitutes include other variants within the A54SX16A series with different speed grades or packages, such as A54SX16A-TQG144 or A54SX16A-PQ208. Cross-family replacements may require significant redesign due to architectural differences between antifuse and SRAM-based FPGAs.
