MPC7455 RISC Microprocessor
Hardware Specifications Addendum
for the XPC74n5RXnnnnSx Series
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.
Specifications provided in this document supersede those in
the
MPC7455 RISC Microprocessor Hardware
Specifications,
Rev. 0 or later, for the part numbers listed in
Table A
only. Specifications not addressed herein are
unchanged. Because this document is frequently updated,
refer to http://www.freescale.com or contact your Freescale
sales office for the latest version.
Note that headings and table numbers in this document are
not consecutively numbered. They are intended to
correspond to the heading or table affected in the general
hardware specification.

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.

Notes
Notes:
1. These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power (OV
DD
and
GV
DD
) or PLL supply power (AV
DD
). OV
DD
and GV
DD
power is system dependent, but is typically <20% of V
DD
power.
Worst case power consumption for AV
DD
< 3 mW.
2. Maximum power is measured at nominal V
DD
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 nominal V
DD
and 65°C 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.

Notes:
1. Processor core frequencies supported by parts addressed by this specification only. Parts addressed by other specifications
may support other maximum core frequencies.
2. 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
