This document describes part-number-specific changes to recommended operating conditions

and revised electrical specifications, as applicable, from those described in the general

MPC7457 RISC Microprocessor Hardware Specifications (Order No. MPC7457EC). The

MPC7457 and MPC7447 are implementations of the PowerPC™ microprocessor family of

reduced instruction set computer (RISC) microprocessors.

Specifications provided in this document supersede those in the MPC7457 RISC

Microprocessor Hardware Specifications, Rev. 2 or later, for the part numbers listed in

Table A only. This document is primarily concerned with the MPC7457; however, unless

otherwise noted, all information herein also applies to the MPC7447 part numbers listed in

Table A. 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.
