This document describes part-number-specific changes to recommended operating conditions and revised electrical specifications, as applicable, from those described in the general MPC7448 RISC Microprocessor Hardware Specifications.
The document describes part‑number‑specific changes to the recommended operating conditions and electrical specifications of the MPC7448 PowerPC® microprocessor. It supersedes the general hardware specifications for the MC7448Txxnnnnmx series and lists the affected Freescale part numbers.
Key tables include core supply voltages for each speed grade, power‑consumption figures for various operating modes, clock AC timing specifications, and the supported voltage‑frequency derating curves. Part‑number marking conventions and revision history are also provided.
| Core supply voltage (1000N) | 1.0 V ± 50 mV |
|---|---|
| Core supply voltage (1700L) | 1.3 V +20/-50 mV |
The devices support voltage and frequency derating, allowing the core voltage (VDD) to be reduced when the maximum core frequency is also lowered.
