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
voltage (VDD) may be reduced if the reduced maximum processor core frequency requirements are
observed. The supported derated core voltage, resulting maximum processor core frequency (fcore), and
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.
