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.motorola.com/semiconductors or to your Motorola

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.

Part numbers addressed in this document are listed in Table A.

Note: The X prefix in a Motorola part number designates a “Pilot Production Prototype” as defined by

Motorola 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.
