产品概述
The MPC82xx series PowerQUICC II Processor with PCI, USB and communications processor module. It include on a single-chip a 32-bit Power Architecture? core that incorporates memory management units (MMUs) and instruction and data caches and that implements the power architecture instruction set, a modified communications processor module (CPM) and an integrated security engine (SEC) for encryption (the MPC8272 and the MPC8248 only). It targets networking equipment requiring encryption capabilities, such as small and medium enterprise (SME) routers, VPN and firewall routers, wireless access points, residential gateways and xDSL equipment. It features dual-core architecture that combines the 603e core with a separate RISC-based communications processor module. High-performance operation with CPU frequencies scaling to 400MHz, CPM frequencies at up to 200MHz and bus speeds up to 100MHz.
