Procurement Notes

Verify the specific suffix 'ZT' against official NXP documentation to confirm package type and temperature range. Ensure the ordering information matches the exact part number MPC852TZT50A. Cross-reference the datasheet revision for any errata or updates relevant to this specific manufacturing lot.

Selection Notes

Select this component for applications requiring a 32-bit RISC controller with integrated communication peripherals. Consider the 1.8 V core and 3.3 V I/O requirements for power supply design. Evaluate thermal performance using junction-to-ambient resistance values provided in the datasheet for the specific board configuration.

Part Context

This part belongs to the MPC860 PowerQUICC family derivatives. It serves as a subset of the broader MPC82xx and MPC866 series, focusing on cost-effective integration of processing and communication functions. The MPC852T shares architectural similarities with other members of the PowerQUICC line while offering specific peripheral configurations.

Replacement Considerations

Consult the MPC866 PowerQUICC Family Reference Manual for functional comparisons. Potential substitutes within the same family include variants like the MPC852TVR100, but verify pinout and electrical characteristics carefully.
