Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status and check for specific packaging suffixes if lead-free handling is required. Review datasheet revision history for any recent manufacturing changes or pinout updates before finalizing procurement orders.

Selection Notes

Select this model when 48,000 system gates and 208 I/O pins are required in a PQFP package. Ensure the -1 speed grade meets timing constraints for 240 MHz applications. Verify that the Industrial temperature grade (-40°C to +85°C) aligns with environmental specifications.

Part Context

This part belongs to the Actel SX-A FPGA family, utilizing antifuse technology for nonvolatile configuration. It represents a mid-range capacity device within the series, offering a balance between logic density and pin count suitable for moderate complexity embedded logic applications.

Replacement Considerations

Direct replacements include other A54SX32 variants with different packages such as A54SX32-BGG313 or A54SX32A-FGG256A. Verify pin compatibility and thermal characteristics when substituting BGA or FBGA packages for the PQFP form factor.

FAQ

What is the maximum internal clock frequency supported by the A54SX32-1PQG208?

The device supports internal clock frequencies up to 350 MHz, though the system performance speed grade is rated at 240 MHz.

Does the A54SX32-1PQG208 support hot-swapping?

Yes, the I/Os are configured to be hot-swappable, except for 3.3 V PCI configurations. Outputs remain high impedance until normal operating conditions are reached.
