SMSC Launches MediaLB Device Interface Macro IP Supporting 6-Pin MediaLB

Hauppage, New York (US), February 2, 2010 - SMSC (NASDAQ: SMSC), a leading semiconductor company that provides Smart Mixed-Signal Connectivity™ solutions, today announced the availability of its OS62420 MediaLB® Device Interface Macro IP including 6-pin support.

This new IP is designed specifically to meet high-performance data transfer requirements and offers efficient, seamless integration into systems-on-chip (SoCs). The macro offers a complete MediaLB device supporting both single-ended MediaLB 3-Pin and additionally the new differential MediaLB 6-Pin interfaces to Media Oriented Systems Transport (MOST®) Intelligent Network Controllers (INICs). The interface offers max. 1024 frame samples (FS) equaling 49.2 MBIt/s in a 48kHz MOST network in MediaLB 3-Pin mode and max. 8192 FS equaling 330 MBIt/s in MediaLB 6-Pin mode. The macro features an Advanced Microcontroller Bus Architecture (AMBA®) 2.0-compliant user interface (AMBA high performance bus and AMBA peripheral bus) for connection to the SoC’s system architecture.

MediaLB is a chip-to-chip interface that enables connectivity of application ICs with the MOST network interface controllers. MediaLB device interfaces can be implemented royalty-free. MediaLB has gained wide support with major semiconductor companies and currently there are 23 licensees using the MediaLB standard in their automotive infotainment products. Additional information is available for download at www.medialb.de.

Key features of the OS62420 device interface macro block include:

• Implements MediaLB specification-compliant link layer
