It offers up to 113 user-programmable I/Os, three global clock networks, and deterministic timing characteristics.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration.
• Supports hot-swap compliant I/Os allowing power-up/down in any order without supply voltage sequencing requirements.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II and boundary-scan testing compliant with IEEE Standard 1149.1.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Low-power, high-performance designs requiring nonvolatile configuration
• Systems requiring hot-swappable interface capabilities
• Applications needing deterministic timing and user-controllable delays

Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the required speed grade against the official datasheet matrix. Confirm that the 'G' suffix indicates RoHS compliant packaging if environmental compliance is mandatory. Ensure the temperature grade matches the intended operating environment specifications.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate external configuration memory. Consider the SX-A family for designs needing mixed-voltage I/O support and hot-swap compatibility. Evaluate the 12,000 gate capacity against logic utilization requirements before finalizing the part number.

Part Context
