Procurement Notes

Verify the specific ordering suffix 'F' against official Microchip documentation to confirm speed grade and temperature range. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component for designs requiring high-speed logic with nonvolatile storage and robust security features. Ensure the 144-pin TQFP package fits the PCB layout constraints. Verify that the 113 available I/Os meet the interface requirements and that the 24,000 gate capacity is sufficient for the target logic complexity.

Part Context

This part belongs to the Actel/Microchip SX-A FPGA family, which is characterized by its sea-of-modules architecture and patented antifuse technology. The family offers various gate counts and packages, providing a scalable platform for low-power, high-performance applications across commercial, industrial, and military temperature grades.

Replacement Considerations

Cross-reference with other A54SX16A variants such as A54SX16A-TQ144 or A54SX16A-PQ208 for package differences. Check datasheet notes regarding discontinued speed grades like -3 when selecting alternative speed options within the same device family.

FAQ

How does the SX-A architecture ensure design security?

The SX-A family uses metal-to-metal antifuses that are virtually impossible to distinguish between programmed and unprogrammed states. Additionally, FuseLock technology prevents reverse engineering and unauthorized reading of the configuration data.

What are the clocking resources available in the A54SX16A?

The A54SX16A provides three clock networks: one hardwired HCLK and two routed global clocks (CLKA and CLKB). Unlike larger devices in the family, it does not include quadrant clocks.

Can the I/Os be used for hot-swapping applications?

Yes, most SX-A I/Os are hot-swap compliant, meaning they do not sink current when the device is unpowered. However, 3.3V PCI I/Os are an exception and are not hot-swappable.
