Device Overview

Summary

OS81110 is available for following applications

• MOST150 Coaxial Networks (MOST150 cPHY) in conjuction with OS82150
• MOST150 Optical Networks (MOST150 oPHY)

General Description

The OS81110 is a Single Network Port highly integrated Intelligent Network Interface Controller (INIC) for the 150 Mbps MOST Network (MOST150) with support for both optical physical layers (oPHY) and coaxial (coax) (*) physical layers (cPHY) that can efficiently handle audio, video, packet, and control data for infotainment and Advanced Driver Assistance Systems (ADAS).

The classic ring topology with dual-simplex communication is supported by oPHY and cPHY. The support of cPHY is enabled with the use of the external transceiver IC OS82150.

The OS81110 offers following state-of-the-art industry standards as user interfaces: I2C, Streaming Port, MediaLB, SPI, TSI. From software side, it is compatible with MOST NetServices.

INIC provides encapsulation of all low-level functions necessary to develop a MOST-compliant device, significantly simplifying MOST implementation in a node. Supervision of the application is also provided, including a protection mode that is entered when an application is not present (i.e. start-up) or the External Host Controller (EHC) malfunctions. This protection mode prevents application malfunctions from influencing the integrity of the network and the system.

INIC includes the INIC Software Stack, which provides MOST-compliant real-time behavior. Integration of the INIC Software Stack significantly relieves the EHC from real-time processing tasks.

The INIC makes a MOST device accessible according to the rules of the MOST Specification, even without participation from the External Host Controller (EHC). The INIC provides a message-based interface for control and packet data. Configuration is encapsulated within a Function Block (FBlock INIC), which allows the EHC to manage INIC in the same way as other functions in the system.

To purchase the OS81110 or obtain additional information, please contact anyMicrochip sales representative or authorized worldwide distributor.
