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.
