This hardware specification is primarily concerned with the PowerPC MPC7457; however,
unless otherwise noted, all information here also applies to the MPC7447. The MPC7457 and
MPC7447 are implementations of the PowerPC microprocessor family of reduced instruction
set computer (RISC) microprocessors. This hardware specification describes pertinent
electrical and physical characteristics of the MPC7457. For functional characteristics of the
processor, refer to the MPC7450 RISC Microprocessor Family User’s Manual.
This hardware specification contains the following topics:

1.1 Overview
The MPC7457 is the fourth implementation of the fourth generation (G4) microprocessors
from Motorola. The MPC7457 implements the full PowerPC 32-bit architecture and is
targeted at networking and computing systems applications. The MPC7457 consists of a
processor core, a 512-Kbyte L2, and an internal L3 tag and controller that support a glueless
backside L3 cache through a dedicated high-bandwidth interface. The MPC7447 is identical
to the MPC7457 except that it does not support the L3 cache interface.
