First MOST150 INIC supporting USB 2.0 high-speed device interface and coaxial physical layer

12 MAY 2013

Microchip announces the OS81118, the first MOST150 Intelli­gent Network Interface Con­troller (INIC) with a USB 2.0 high-speed device port and an integrated coax transceiver.
The MOST150 technology was successfully deployed in the first car models in 2012. Now, Microchip announces the latest member of its MOST150 INIC family to continue the success story of MOST® in the future. With its USB 2.0 port, including USB PHY and High-Speed Inter-Chip interface (HSIC), the OS81118 allows designers to create in-car mobile and Wi-Fi® connectivity applications on the MOST150 network by connecting a standard Wi-Fi/3G/LTE module via USB. This simple solution reflects today’s market demands for consumer applications within the automotive environment, such as Internet access, e-mail, social networking and local services. Furthermore, the OS81118 enables automotive engineers to connect the most up-to-date multi-core consumer Systems-on-a-Chip (SoCs) to in-vehicle MOST networks. Besides the optical physical layer (oPHY) interface, the OS81118 integrates a coax transceiver, which opens a cost-reduction path on the MOST physical layer. Additionally, this coaxial physical layer (cPHY) could be used for Advanced Driver Assistance Systems (ADAS).
The OS81118 supports the trend in the infotainment market to use high-end SoCs, developed for consumer and mobile devices, within automotive applications. However, those SoCs have no automotive-specific interfaces, such as CAN, LIN, MediaLB® or MOST. The high-speed USB port on the OS81118 makes it easy to connect SoCs to any MOST150 automotive network, with the added flexibility provided by the coax transceiver.
