Freescale Semiconductor

General Parameters

5.3

Voltage and Frequency Derating

To reduce power consumption, these devices support voltage and frequency derating in which the core

power consumption are provided in Table 11. Only those parameters in Table 11 are affected; all other

parameter specifications are unaffected.

9.2

Power Supply Design and Sequencing

The power supply design and sequencing requirements of the devices described here are identical to those

described in the MPC7448 RISC Microprocessor Hardware Specifications.
