General Parameters

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.

core_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 f

core

General Parameters

5.3 Voltage and Frequency Derating

To reduce power consumption, these devices support voltage and frequency derating in which the core

voltage (V

) may be reduced if the reduced maximum processor core frequency requirements are

observed. The supported derated core voltage, resulting maximum processor core frequency (f

core

), and

power consumption are provided in Table 11. Only those parameters in Table 11 are affected; all other

parameter specifications are unaffected.

9.2 Power Supply Design and Sequencing

The power supply design and sequencing requirements of the devices described here are identical to those

described in the MPC7448 RISC Microprocessor Hardware Specifications.

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. Core voltage for 1400 MHz devices currently in production (date code of 0613 and later) is 1.15 V ± 50 mV; all such devices

have the MC product code. The 1400 MHz devices with date code of 0612 and prior specified core voltage of 1.1 V ± 50 mV;

this includes all 1400 MHz devices with the PPC product code. See Section 11.3, “Part Marking,” for information on part

marking.
