Freescale Semiconductor 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 at http://www.Freescale.com. 1Overview 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 high-bandwidth interface. The MPC7447 is identical to the MPC7457 except that it does not support the L3 cache interface. Figure 1 shows a block diagram of the MPC7457. The core is a high-performance superscalar design supporting a double-precision floating-point unit and a SIMD multimedia unit. MPC7457EC Rev. 5, 09/2004 Contents 1.
