The MPC850 integrated communications microprocessor 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 and Asynchronous Transfer Mode (ATM), was specifically designed for cost-sensitive remote access, xDSL and telecom applications. As a low-cost implementation of the MPC860, it provides excellent price/performance, along with system enhancements such as Universal Serial Bus (USB) support and a larger dual-port RAM (8KB).
