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.
