MPC7450 RISC Microprocessor Hardware Speciﬁcations

MOTOROLA

Electrical and Thermal Characteristics

Table 7 provides the power consumption for the MPC7450.

1.5.2

AC Electrical Characteristics

This section provides the AC electrical characteristics for the MPC7450. After fabrication, functional parts

are sorted by maximum processor core frequency as shown in Section 1.5.2.1, “Clock AC Speciﬁcations,”

and tested for conformance to the AC speciﬁcations for that frequency. The processor core frequency is

determined by the bus (SYSCLK) frequency and the settings of the PLL_EXT and PLL_CFG[0:3] signals.

Parts are sold by maximum processor core frequency; see Section 1.11, “Ordering Information.”

Notes:

1. These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power

(OVDD and GVDD) or PLL supply power (AVDD). OVDD and GVDD power is system dependent, but is typically

<20% of VDD power. Worst case power consumption for AVDD < 3 mW.

2. Maximum power is measured at nominal VDD (see Table 4) while running an entirely cache-resident, contrived

sequence of instructions which keep the execution units, with or without AltiVec, maximally busy.

3. Typical power is an average value measured at the nominal recommended VDD (see Table 4) in a system while

running a typical code sequence.

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.
