for the XPC74

This document describes part-number-specific changes to
recommended operating conditions and revised electrical
specifications, as applicable, from those described in the
general MPC7455 RISC Microprocessor Hardware
Specifications (Order No. MPC7455EC). The MPC7455 is a
PowerPC™ microprocessor.

Note: The X prefix in a Freescale part number designates a “Pilot Production Prototype” as defined by Freescale SOP 3-13.

These are from a limited production volume of prototypes manufactured, tested, and Q.A. inspected on a qualified
technology to simulate normal production. These parts have only preliminary reliability and characterization data. Before
pilot production prototypes may 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 while shipping pilot
production prototypes.

Table 7 provides the power consumption for the MPC7455 part number described herein.

Table 7. Power Consumption for MPC7455

Processor (CPU)

Frequency

1000 MHz

Full-Power Mode

Ty pi ca l 35.5 W 1, 3

Maximum 50.0 W 1, 2

Doze Mode

Ty pi ca l — W 1, 2, 4

Nap Mode

Ty pi ca l 3.7 W 1, 2

Sleep Mode

Ty pi ca l 1.7 W 1, 2

Deep Sleep Mode (PLL Disabled)

Ty pi ca l 1.1 W 1, 3

Notes:

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

) or PLL supply power (AVDD). OVDD and GVDD power is system dependent, but is typically <20% of VDD power.

DD

Worst case power consumption for AV

2. Maximum power is measured at nominal V

< 3 mW.

DD

while running an entirely cache-resident, contrived sequence of instructions

DD

which keep the execution units, with or without AltiVec™, maximally busy.

3. Typical power is an average value measured at nominal V

and 65°C in a system while running a typical code sequence.

DD

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.
