The MPC850, whichincludes support for Ethernet, is specifically designed for cost-sensitive,remote-access, and telecommunications applications. It is provides functionssimilar 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 MPC850integrates system functions, such as a versatile memory controller and acommunications processor module (CPM) that incorporates a specialized,independent RISC communications processor (referred to as the CP). Thisseparate 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 (MPC850SR and MPC850DSL), HDLC and a number of other protocols, along with a transparent mode of operation.• One USB channel• Two serial management controllers (SMCs)2• One I C port• One serial peripheral interface (SPI). Table 1-1 shows the functionality supported by the members of the MPC850 family.Table 1-1.
