Notes:
1. The P prefix in a Freescale part number designates a “Pilot Production Prototype” as defined by Freescale SOP 3-13. These
parts have only preliminary reliability and characterization data. Before pilot production prototypes can be shipped, written
authorization from the customer must be on file in the applicable sales office acknowledging the qualification status and the
fact that product changes may still occur as pilot production prototypes are shipped.
2. See
Section 5.1, “DC Electrical Characteristics,”
for information regarding V

specifications for 1400 MHz devices.

Notes:
1. These are the recommended and tested operating conditions. Some speed grades in addition support voltage derating; see
Section 5.3, “Voltage and Frequency Derating.”
Proper device operation outside of these conditions and those specified in
Section 5.3, “Voltage and Frequency Derating,”
is not guaranteed.
2. This voltage is the input to the filter discussed in
Section 9.2.2, “PLL Power Supply Filtering,”
in the hardware specifications
and not necessarily the voltage at the AV
DD
pin, which may be reduced from V
DD
by the filter.
3. V
DD
and AV
DD
may be reduced in order to reduce power consumption if further maximum core frequency constraints are
observed. See
Section 5.3, “Voltage and Frequency Derating,”
for specific information.
4. Effective for 1400 MHz devices with date code of 0613 and later; this includes all devices with the ‘PPC’ product code. V
DD
and AV
DD
were specified at 1.1V ± 50 mV for 1400 MHz devices with date code 0612 and prior. See
Section 11, “Part
Numbering and Marking,”
for more information.

General Parameters
Table 7
provides the power consumption for the MPC7448 part numbers described by this document; see
Section 11.1, “Part Numbers Addressed by This Specification,”
for more information. The
MPC7448
RISC Microprocessor Hardware Specifications
presents guidelines on the use of these parameters for
system design. For information on power consumption when dynamic frequency switching is enabled, see
Section 9.8.5, “Dynamic Frequency Switching (DFS),”
in the hardware specifications.
The power consumptions provided in
Table 7
represent the power consumption of each speed grade when
operated at the rated maximum core frequency (see
Table 8).
Freescale sorts devices by power as well as
by core frequency, and power limits for each speed grade are independent of each other. Each device is
tested at its maximum core frequency only. (Note that Deep Sleep Mode power consumption is
independent of clock frequency.) Operating a device at a frequency lower than its rated maximum is fully
supported provided the clock frequencies are within the specifications given in
Table 8,
and a device
operated at a core frequency below its rated maximum will have lower power consumption. However,
inferences should not be made about a device’s power consumption based on the power specifications of
another (lower) speed grade. For example, a 1267 MHz device operated at 1000 MHz may not exhibit the
same power consumption as a 1000 MHz device operated at 1000 MHz.
NOTE
The power consumption information in this table applies when the device
operates at the nominal core voltage indicated in
Table 4.
For power
consumption at derated core voltage conditions, see
Section 5.3, “Voltage
and Frequency Derating.”
