• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements.
• Includes dedicated quadrant clock networks for efficient signal distribution across the die.
• Provides boundary-scan testing capabilities compliant with IEEE Standard 1149.1.

Applications

• High-performance digital logic integration
• PCI-compliant interface designs
• Industrial control systems requiring mixed-voltage I/O

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified suppliers. Confirm that the part matches the specific ordering suffixes for speed grade and temperature rating. Ensure compliance with RoHS directives if required by the application environment.

Selection Notes

Select this model for applications requiring high gate density and deterministic timing performance. Consider the FBGA package constraints during PCB layout. Verify that the design utilizes the available global and quadrant clock resources effectively for optimal signal integrity.

Part Context

This component belongs to the Actel SX-A FPGA family, characterized by nonvolatile antifuse technology. It serves as a single-chip solution for low-power, high-speed designs, replacing complex CPLDs or gate arrays in various embedded applications.

Replacement Considerations

Direct replacements are limited due to the proprietary antifuse architecture. Evaluate other SX-A family members like the A54SX32A for lower capacity needs. Cross-family migration requires significant design re-verification.
