Procurement Notes

Verify the specific suffix 'CZT50A' against official NXP documentation to confirm package type, temperature range, and speed grade. Ensure power supply sequencing adheres to the requirement that VDDL must not exceed VDDH during power-on reset. Confirm RoHS compliance status as indicated in current datasheets.

Selection Notes

Select this component for applications requiring integrated communications control and Ethernet connectivity. Evaluate thermal resistance requirements based on the expected ambient temperature and board layout. Ensure the design accommodates the 1.8-V core and 3.3-V I/O voltage levels with appropriate decoupling capacitors near the package pins.

Part Context

This part belongs to the MPC860 PowerQUICC family, which are quad integrated communications controllers. The MPC852T serves as a derivative within this family, offering a subset of features optimized for cost-sensitive communication applications while maintaining compatibility with the broader PowerPC architecture ecosystem.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers. Verify functional equivalence regarding pinout, voltage levels, and performance specifications before substitution.
