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.
• • • • One USB channel Two serial management controllers (SMCs) One I2C port One serial peripheral interface (SPI).
