Voltage and Frequency Derating

Voltage and frequency derating is no longer supported for part numbers described by this document

beginning with datecode 0613. (See Section 11, “Part Numbering and Marking,” for information on date

code markings.) It is supported by some MPC7448 part numbers which target low-power applications; see

Section 11.2, “Part Numbers Not Fully Addressed by This Document” and the referenced MPC7448

Hardware Specification Addenda for more information on these low-power devices. For those devices

which previously supported this feature, information has been archived in the Chip Errata for the

MPC7448 (document order no. MPC7448CE).
