1 / 52 page  The MPC7450 is a reduced instruction set computing (RISC) microprocessor that implements the PowerPC instruction set architecture. This document describes pertinent electrical and physical characteristics of the MPC7450. For functional characteristics of the processor, refer to the MPC7450 RISC Microprocessor Family User’s Manual. This document contains the following topics: Topic Page Section 1.1, “Overview” 1 Section 1.2, “Features” 3 Section 1.3, “Comparison with the MPC7400” 7 Section 1.4, “General Parameters” 9 Section 1.5, “Electrical and Thermal Characteristics” 9 Section 1.6, “Pin Assignments” 30 Section 1.7, “Pinout Listings for the 483 CBGA Package” 31 Section 1.8, “Package Description” 34 Section 1.9, “System Design Information” 36 Section 1.10, “Document Revision History” 48 Section 1.11, “Ordering Information” 49 To locate any published updates for this document, refer to the website at http://www.motorola.com/semiconductors 1.1 Overview The MPC7450 is the third implementation of the fourth generation (G4) microprocessors from Motorola. The MPC7450 implements the full PowerPC 32-bit architecture and is targeted at networking and computing systems applications. The MPC7450 consists of a processor core, a 256-Kbyte L2, and an internal L3 tag and controller which support a glueless backside L3 cache through a dedicated high bandwidth interface. Figure 1 shows a block diagram of the MPC7450. 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 interface to main memory and other system resources. The L3 interface supports 1 or 2 Mbytes of external SRAM for L3 cache data.
