PC7457  
Description  
The PC7457 is implementations of the PowerPC® microprocessor family of reduced  
instruction set computer (RISC) microprocessors. This document describes pertinent  
electrical and physical characteristics of the PC7457.  
The PC7457 is the fourth implementation of the fourth generation (G4) microproces-  
sors from Freescale. The PC7457 implements the full PowerPC 32-bit architecture  
and is targeted at networking and computing systems applications. The PC7457 con-  
sists of a processor core, a 512 Kbyte L2, and an internal L3 tag and controller which  
support a glueless backside L3 cache through a dedicated high-bandwidth interface.  
The core is a high-performance superscalar design supporting a double-precision  
floating-point unit and a SIMD multimedia unit. The memory storage subsystem sup-  
ports the MPX bus interface to main memory and other system resources. The L3  
interface supports 1, 2, or 4M bytes of external SRAM for L3 cache and/or private  
memory data. For systems implementing 4M bytes of SRAM, a maximum of 2M bytes  
may be used as cache; the remaining 2M bytes must be private memory.  
Note that the PC7457 is a footprint-compatible, drop-in replacement in a PC7455  
application if the core power supply is 1.3V.
