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.

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. 600 733

Notes: 1. These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power (OVDD and GVDD) or PLL supply power (AVDD). OVDD and GVDD power is system dependent, but is typically <5% of VDD power. Worst case power consumption for AVDD < 3 mW. 2. Maximum power is the maximum measured at nominal VDD and maximum operating junction temperature (see Table 4) while running an entirely cache-resident, contrived sequence of instructions which keep all the execution units maximally busy. 3. Typical power is an average value measured at the nominal recommended VDD (see Table 4) and 65°C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. 4. Doze mode is not a user-definable state; it is an intermediate state between full-power and eit.
