Description
The OS81082 INIC is a highly integrated Intelligent Network
Interface Controller (INIC) for the 50 Mbit/s MOST Network
(MOST50). The integrated electrical physical layer (ePHY) signal
conditioning circuitry offers differential I/O that directly interfaces
to a passive ePHY transformer. This enables MOST data transmis-
sion via unshielded twisted pair (UTP) cable.
The INIC provides full encapsulation of all functions necessary to
develop a MOST compliant device. It allows an easy implementa-
tion of MOST into a device.
The INIC also provides supervision of the application, and a
protected mode is entered during malfunction or absence of an
application (i.e., start-up). This protected mode prevents applica-
tion malfunctions from influencing the integrity of the network
and the system.
The INIC includes the MOST NetServices stack’s MiniKernel, thus
providing MOST compliant real time behavior. This significantly
relieves the External Host Controller (EHC) from realtime
processing tasks.
