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. 2S e e Section 5.1, “DC Electrical Characteristics,” for information regarding V DD specifications for 1400 MHz device.

- These are the recommended and tested operating conditions. Some speed grades in addition support voltage derating; see
Section 5.3, “Voltage and Frequency Derating,” is not guaranteed.
- 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 AVDD pin, which may be reduced from VDD by the filter.
- V DD 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.

5.2.1 Clock AC Specifications
Table 8 provides the clock AC timing specifications for the MPC7448 part numbers discussed here. Table 7. Power Consumption for MPC7448 at Maximum Rated Frequency
- These values specify the power consumption for the core power supply (V DD) at nominal voltage and apply to all valid
- Typical nominal power consumption is an average value measured at the nominal recommended V DD (see Table 4) and
tested but periodically sampled.
- Maximum power consumption is the average measured at nominal VDD and maximum operating junction temperature (see
- Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode. As a
result, power consumption for this mode is not tested.
- Typical thermal power consumption is an average value measured at the nominal recommended V DD (see Table 4) and
tested but periodically sampled.
- Typical power consumption for these modes is measured at the nominal recommended VDD (see Ta bl e 4) and 105°C in the
mode described. This parameter is not 100% tested but is periodically sampled.
- Power consumption for the 1267 MHz device is intentionally constrained via testing and sorting to assure low power
consumption for this device.
