Procurement Notes

Verify component authenticity through authorized channels due to potential availability of refurbished units. Confirm RoHS status as this specific variant may contain lead. Ensure storage conditions respect moisture sensitivity level 3 requirements before reflow soldering processes.

Selection Notes

Select this model when nonvolatile configuration and high reliability are required over higher-density alternatives. Compare against the A54SX16A series if extended industrial or military temperature grades beyond the standard commercial range are necessary for the specific application environment.

Part Context

This component belongs to the Microsemi SX-A family of flash-based FPGAs. It serves as a mid-range logic density option within the portfolio, bridging lower-density devices like the A54SX08A and higher-capacity variants such as the A54SX32A. The CQFP-208 package provides a ceramic form factor suitable for harsh environments.

Replacement Considerations

The A54SX16A-CQ208B offers similar logic resources but may differ in speed grade or temperature specifications. Verify pin compatibility and electrical characteristics before substitution.
