• Supports hot-swap capabilities and power-up/down friendly operation without requiring specific sequencing for supply voltages.
• Includes configurable I/O standards supporting mixed-voltage operation with 5 V input tolerance and drive strength across various logic families.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring nonvolatile single-chip solutions with secure programming

Procurement Notes

Verify the specific ordering suffix to confirm the package type, speed grade, and temperature range match the design requirements. Confirm RoHS compliance status as packaging options vary. Check for end-of-life notifications or discontinuance notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this model for applications requiring approximately 24,000 system gates with a 144-pin footprint. Ensure the design utilizes the -1 speed grade for performance levels approximately 15% faster than standard. Verify that the 2.5 V core voltage aligns with the available I/O voltage domains.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated on 0.22 μm / 0.25 μm CMOS process technology. The family offers varying capacities from 8,000 to 108,000 system gates, with the A54SX16A providing a mid-range solution optimized for cost-effective, high-performance designs.

Replacement Considerations
