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.
