Motorola Part Numbers Affected: MC7457TRX1000NC MC7457TRX733NC MC7447TRX1000NB MC7447TRX733NB
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. Part numbers addressed in this document are listed in Table A.
