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 speciﬁcally 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.

The CPM of the MPC850 supports up to seven serial channels, as follows:

•

One or two serial communications controllers (SCCs). The SCCs support Ethernet,

ATM (MPC850SAR), HDLC and a number of other protocols, along with a

transparent mode of operation.
