The MPC7447A series high-performance low-power RISC Microprocessor implements the full PowerPC 32-bit architecture and is targeted at networking applications. Key architectural features include 512kB of on-chip L2 cache, a 64-bit bus interface and a full 128-bit implementation of our AltiVec™ technology. Designed as pin-compatible replacements for MPC7447 products, this new processor has been shown to reach speeds of 1.5GHz. MPC7447A processor benefit from our silicon-on-insulator (SOI) process technology, engineered to help deliver significant power savings without sacrificing speed. Low-power versions of the MPC7447A are available. The MPC7447A offers eight instruction BAT and data BAT registers to help support lightweight embedded operating systems, enabling more large tables of data. The processors also provide cache locking to the L1 caches so that key performance algorithms and code can be locked in the L1 cache.
