Implementing MOSTCO's Roadmap
Despite the media hype about Ethernet in the car, the MOST technology is still far more established in the infotainment domain than any other networking technology. The current roadmap, introduced at this year’s MOST Forum has been enhanced; additional waypoints and goals have been added to the roadmap. This article addresses the most significant aspects of these goals, the status and the outlook from Microchip’s perspective.
three-node-reference design for MOST50 and MOST150 speed grades. Additional options simplifying the design are available now. A number of plug-and-play hardware demonstration devices are available utilizing the UNICENS software concept. They encapsulate MOST specific functions and central configuration. “Slim devices” have no MOST-specific software; some operate even without an application microcontroller. In an available Microchip demonstration system, the MOST Ethernet Packet Channel is used for device control over IP. The use of the Linux device drivers make MOST channels look like Ethernet ports or audio devices. For the physical layer, frontend reference designs have been devised which meet OEMs’ emissions and immunity requirements. They are available for MOST50 UTP and MOST150 coax.

Focus on roll out of MOST150

The deployment and roll out of MOST150 optical runs smoothly at Audi, Daimler, Kia and Volvo. New car flagship models were released to the market, such as Audi’s A4, Daimler’s E-class, Kia’s K900 and Volvo’s XC90. Further deployment of MOST150 optical in new models is ongoing.

In order to facilitate the introduction of MOST150 coaxial in the market, MOST150 cPhy Measurement Guideline and MOST150 cPhy Compliance Verification Procedure-Physical Layer were released in 2015. This was achieved in a MOST Cooperation working group, chaired by Honda and with contributions from Daimler, TE Connectivity and Microchip. Microchip released an EMC reference design compliant with the MOST cPhy Physical Layer Specification in 2015. This reference design features OS82150, OS81110, OS85650 and MPM85000.  To further enable development and accelerate time to market, the OS82150 is supported by K2L’s OS81110 cPhy Evaluation Board and K2L’s OptoLyzer® MOCCA Bundles. The OS81110 cPhy Evaluation Board encapsulates an entire MOST150 network device. An integrated OS85650 I/O Companion Chip provides I/O port expansion for additional application flexibility. The OptoLyzer MOCCA Bundle combines the capabilities of the popular OptoLyzer Suite graphical user interface with the advantages of the OptoLyzer MOCCA multi-bus hardware interface.
