Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm RoHS compliance status, which may vary by revision, and check for specific errata documents related to interrupt handling or core functionality before integration into new designs.

Selection Notes

Select this processor for applications requiring robust embedded networking capabilities with legacy PowerPC compatibility. Evaluate thermal requirements against the specified operating range and ensure PCB layout supports the 783-pin flip-chip ball grid array package dimensions and pitch specifications.

Part Context

This component belongs to the PowerQUICC III family, designed for communications and infrastructure markets. It combines system-level interface support with embedded Power Architecture processors. The MPC8540 series was widely used in routers and switches before being succeeded by newer generations.

Replacement Considerations

Consult official substitution guides for compatible upgrades within the MPC85xx lineage. Verify pinout and voltage compatibility when considering alternative frequencies or enhanced feature sets from successor models.
