MPC850UM

The MPC850UM  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 MPC850UM ,which includes support for Ethernet,is specifically designed for cost-sensitive,remote-access,and telecommunications applications.It is provides functions similar to it,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 MPC850UM  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 following list summarizes the main features of the MPC850UM :(1)Embedded single-issue, 32-bit MPC8xx core (implementing the PowerPC architecture) with thirty-two 32-bit general-purpose registers (GPRs);(2)Advanced on-chip emulation debug mode;(3)Data bus dynamic bus sizing for 8, 16, and 32-bit buses;(4)Completely static design (080 MHz operation);(5)One universal serial bus controller (USB)-Supports host controller and slave modes at 1.5 Mbps and 12 Mbps.
