Procurement Notes

Verify the specific suffix 'A' against official Microchip documentation to confirm if it denotes a distinct revision or packaging variant, as standard datasheets may list base part numbers. Confirm RoHS compliance status and check for End-of-Life notifications or discontinuance notices prior to procurement. Ensure the supplier provides valid traceability documents for automotive-grade components.

Selection Notes

Select this device when designing for automotive environments requiring robust logic density and nonvolatile configuration. The TQFP-144 package offers a balance of I/O count and pin pitch for surface-mount assembly. Consider the 250 MHz internal clock speed for complex state machines and datapath logic. Verify that the 2.5 V core voltage aligns with the target system's power distribution network.

Part Context

This component belongs to the Actel SX-A Automotive Family FPGAs, which utilize a sea-of-modules architecture optimized for high performance and low power consumption. The SX-A series integrates combinatorial and register cells with dedicated routing resources like DirectConnect and FastConnect to minimize signal propagation delays. This family replaces multiple CPLDs with a single-chip solution.

Replacement Considerations

Consult Microchip for current equivalents. Previous generation SX devices or other antifuse FPGAs may offer similar gate counts but lack automotive qualification. Verify pinout compatibility and voltage levels before substituting.
