The OS8565x I/O Companion family ICs are High-Performance MediaLB-I/O-Port Expanders for MOST® Intelligent Network Interface Controllers (INICs).

With its multiple interfaces, powerful routing engine and the DTCP co-processor, the OS85650 can be used for various audio and video applications such as Head Units, Rear Seat Entertainment, Amplifiers, TV-Tuners and Video Displays. The OS85652 is the pin-compatible version without a DTCP co-processor.

The I/O-Companion works together with SMSC INICs for all MOST speed grades (MOST25, MOST50 and MOST150) and can replace many of today’s expensive FPGA solutions.

The primary function of the OS8565x is to route data streams simultaneously between industry standard application I/O interfaces, including MediaLB® (3-Pin and 6-Pin), HBI, TSI, SPI and I²S. It is the first MediaLB 6-Pin device that supports all features of the MOST150 multimedia network. Together with the 16 bit parallel Host Bus Interface (HBI), it enables a high-speed connection between the INIC150 and multiple External Host Controllers (EHCs) with over 300Mbit/s. It is also possible to use the OS85650 as a bridge between MediaLB 6-Pin and MediaLB 3-Pin devices.

TrueAuto™ is SMSC's automotive quality process. It has proven its ability to deliver leading-edge quality and services for IC device products to fulfill the needs of the most demanding automotive customers. TrueAuto is a proven total automotive-grade quality approach. TrueAuto IC device robustness begins with SMSC’s design for reliability techniques within the silicon IC itself: automotive-grade robustness and testability are designed into the IC. Once available in silicon, the IC is fully-characterized and qualified over a multitude of operating parameters to prove quality under the harshest conditions. In this, SMSC’s TrueAuto approach significantly exceeds the usual automotive reliability standards and customer- specific requirements and goes far beyond the stress tests prescribed by the AEC-Q100 specifications. During the fabrication of TrueAuto products, extensive technologies and processes, such as enhanced monitors are used in order to continuously drive improvements in accordance with SMSC’s zero Defects per Million (DPM) goals.
