Microchip Technology Inc. has rolled out what it touts as the first MOST150 intelligent network interface controller (INIC) with a USB 2.0 high-speed device port and an integrated coax transceiver. According to the company, the OS81118 enables automotive engineers to connect the most up-to-date multi-core consumer SoCs to in-vehicle MOST networks.

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 WiFi connectivity applications on the MOST150 network by connecting a standard WiFi/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, the firm noted.

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).

MOST multimedia networking technology enables the interconnection of feature-rich infotainment systems in automobiles, by providing the means to distribute multimedia entertainment functions among the various control devices inside the car. For example, CD or DVD changer, radio, GPS-navigation, mobile-telephone and digital-media interfaces can supply signals to this efficient network. The signals are sent digitally and static-free to the amplifier and monitors.

To further enable development and speed time to market, Microchip also released the Physical+ Interface Board OS81118. This board encapsulates the entire physical hardware interface of a MOST network. The Physical+ Interface Board OS81118 comes with a USB 2.0 interface supporting optical and coaxial physical layers. The Physical+ Interface Board OS81118 is expected to be available in Q3/2013.

The OS81118 is expected to be available for volume production in January 2014. You can apply for early adopter samples today, and sampling production is expected to start in Q3/2013. The OS81118 is offered in a 72-pin QFN package.
