Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Includes Boundary-Scan Testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostics.
• Features deterministic timing through patented metal-to-metal programmable antifuse interconnect elements.

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• High-performance digital logic integration requiring low power consumption
• Systems requiring secure nonvolatile configuration without external bitstream interception

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the -1 speed grade designation aligns with the required timing constraints for the target application. Ensure the FBGA-144 package dimensions match the PCB footprint specifications during the procurement phase.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the 144-pin FBGA package fits the available board space and thermal management requirements. Consider the 111 available user I/Os to ensure adequate connectivity for the system interfaces.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The SX-A series is designed for cost-effective, single-chip solutions offering high performance and low power consumption. The A54SX32A variant specifically targets applications needing moderate gate counts with robust security features and flexible I/O configurations.

Replacement Considerations

Compatible substitutes include other devices within the A54SX32A series with different speed grades or packages, such as A54SX32A-FGG144 or A54SX32A-1FGG144I, provided the pinout and electrical characteristics remain compatible. Cross-family replacements require careful verification of gate density and I/O voltage levels.
