MPC7448 Hardware Specifications
Addendum for the
MC7448T
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 MPC7448 is a PowerPC™
microprocessor built on Power Architecture™ technology.
Specifications provided in this document supersede those in
the MPC7448 RISC Microprocessor Hardware
Specifications, Rev. 3 or later, for the part numbers listed in
Table A only. Specifications not addressed herein are
unchanged. Because this document is frequently updated,
refer to the website on the back page of this document or to
your Freescale sales office for the latest version.

Note:
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.

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
3. VDD and AVDD 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.

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 lowe r than its rated maximum is fully
supported provided the clock frequencies are within the specifications given in Table 8, and a device
operated 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 1400 MHz device operated at 1267 MHz will not exhibit the same power
consumption as a 1267 MHz device operated at 1267 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.”
