Hardware Specifications

This document is primarily concerned with the PowerPC™

MPC7447A; however, unless otherwise noted, all

information here also applies to the MPC7447. The

MPC7447A is an implementation of the PowerPC

microprocessor family of reduced instruction set computer

(RISC) microprocessors. This document describes pertinent

electrical and physical characteristics of the MPC7447A. For

functional characteristics of the processor, refer to the

MPC7450 RISC Microprocessor Family Reference Manual.

1 Overview

The MPC7447A is the fifth implementation of the

fourth-generation (G4) microprocessors from Freescale. The

MPC7447A implements the full PowerPC 32-bit

architecture and is targeted at networking and computing

systems applications. The MPC7447A consists of a

processor core and a 512-Kbyte L2.

Figure 1 shows a block diagram of the MPC7447A. The core

is a high-performance superscalar design supporting a

double-precision floating-point unit and a SIMD multimedia

unit. The memory storage subsystem supports the MPX bus

protocol and a subset of the 60x bus protocol to main

memory and other system resources.
