This doc ument descr ibes par t-number -spec ific cha nges to rec ommended op erating condition s
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 a nd table n umbers in th is document a re not cons ecutivel y number ed. 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.
