Part I Overview
The MPC850 is a versatile, one-chip integrated microprocessor and peripheral
combination that can be used in a variety of controller applications, excelling
particularly in communications and networking products. The MPC850, which
includes support for Ethernet, is speci鏗乧ally designed for cost-sensitive,
remote-access, and telecommunications applications. It is provides functions
similar to the MPC860, with system enhancements such as universal serial bus
(USB) support and a larger (8-Kbyte) dual-port RAM.
In addition to a high-performance embedded MPC8xx core, the MPC850
integrates system functions, such as a versatile memory controller and a
communications processor module (CPM) that incorporates a specialized,
independent RISC communications processor (referred to as the CP). This
separate processor off-loads peripheral tasks from the embedded MPC8xx core.
