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

pin, which may be reduced from V

by the filter.

3. V

and AV

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

and AV

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.”

Notes:

1. These values specify the power consumption for the core power supply (V

) at nominal voltage and apply to all valid

processor bus frequencies and configurations. The values do not include I/O supply power (OV

) or PLL supply power

(AV

). OV

power is system dependent but is typically < 5% of V

power. Worst case power consumption for

<13mW.

2. Typical nominal power consumption is an average value measured at the nominal recommended V

(see Ta bl e 4 ) and

65°C 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 V

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 V

(see Table 4) and

105°C 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 V

(see Tab le 4 ) and 105°C 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.
