Procurement Notes

Verify the specific silicon revision level required for your design, as documentation accuracy depends on the revision suffix. Confirm that the ordering suffix matches the desired package type and temperature range. Ensure compatibility with existing board layouts regarding pin assignments and voltage levels before finalizing procurement decisions.

Selection Notes

Select this component when a highly integrated communication processor with hardware security acceleration is required. Consider the 400 MHz core speed and available I/O interfaces against system throughput needs. Evaluate the power dissipation characteristics relative to the thermal solution constraints of the target enclosure.

Part Context

This part belongs to the MPC8347E PowerQUICC II Pro family, representing a next-generation upgrade to the PowerQUICC II series. It builds upon the e300 SoC platform to provide enhanced networking and storage capabilities. The family targets applications requiring high performance in enterprise networking and telecom transmission environments.

Replacement Considerations

NXP recommends using the T1013 or LS1012 families for new designs. Verify functional equivalence if substituting with other MPC83xx variants, noting potential differences in clock speeds, cache sizes, and peripheral availability.
