1 / 56 page  © Freescale Semiconductor, Inc., 2006. All rights reserved. Freescale Semiconductor Technical Data 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. To locate any published updates for this document, refer to the Freescale website located at http://www.freescale.com. 1Overview 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. MPC7447AEC Rev. 5, 01/2006 Contents 1.
