Technical Data
This hardware specification is primarily concerned with the
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.
To locate any published updates for this hardware
specification, refer to the website listed on the back page of
this document.

Overview
The MPC7457 is the fourth implementation of the fourth
generation (G4) microprocessors from Freescale. 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
MPC7457EC
