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. 2 See Section 5.1, "DC Electrical Characteristics," for information regarding VDD specifications for 1400 MHz device.

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 AVDD pin, which may be reduced from VDD by the filter. 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 lower 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."

Notes: 1. These values specify the power consumption for the core power supply (VDD) at nominal voltage and apply to all valid processor bus frequencies and configurations. The values do not include I/O supply power (OVDD) or PLL supply power (AVDD). OVDD power is system dependent but is typically < 5% of VDD power. Worst case power consumption for AVDD < 13 mW. 2. Typical nominal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and 65C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100% tested but periodically sampled. 3. Maximum power consumption is the average measured at nominal VDD and maximum operating junction temperature (see Table 4) while running an entirely cache-resident, contrived sequence of instructions to keep all the execution units maximally busy. 4. 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. 5. Typical thermal power consumption is an average value measured at the nominal recommended VDD (see Table 4) and 105C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. This parameter is not 100% tested but periodically sampled. 6. Typical power consumption for these modes is measured at the nominal recommended VDD (see Table 4) and 105C in the mode described. This parameter is not 100% tested but is periodically sampled. 7. Power consumption for the 1267 MHz device is intentionally constrained via testing and sorting to assure low power consumption for this device.
5.2.1 Clock AC Specifications
Table 8 provides the clock AC timing specifications for the MPC7448 part numbers discussed here. NOTE The core frequency information in this table applies when the device operates at the nominal core voltage indicated in Table 4. For core frequency specifications at derated core voltage conditions, see Section 5.3, "Voltage and Frequency Derating."

Notes: 1. Caution: The SYSCLK frequency and PLL_CFG[0:5] settings must be chosen such that the resulting SYSCLK (bus) frequency, processor core frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating frequencies. Refer to the PLL_CFG[0:5] signal description in Section 9.1.1, "PLL Configuration," in the hardware specifications for valid PLL_CFG[0:5] settings. 8. This reflects the maximum and minimum core frequencies when the dynamic frequency switching feature (DFS) is disabled. fcore_DFS provides the maximum and minimum core frequencies in a DFS mode. 9. Caution: These values specify the maximum processor core and VCO frequencies when the device is operated at the nominal core voltage. If operating the device at the derated core voltage, the processor core and VCO frequencies must be reduced. See Section 5.3, "Voltage and Frequency Derating," for more information. 10.This specification supports the Dynamic Frequency Switching (DFS) feature and is applicable only when one of the DFS modes (divide-by-2 or divide-by-4) is enabled. When DFS is disabled, the core frequency must conform to the maximum and minimum frequencies stated for fcore.
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.
