SMSC Inter-Chip Connectivity Technology Licensed by AMD

HAUPPAUGE, N.Y., Apr 28, 2011 -- SMSC (NASDAQ: SMSC), a leading semiconductor company creating valued connectivity ecosystems, announced today that Advanced Micro Devices, Inc. (NYSE: AMD) has licensed SMSC's patented Inter-Chip Connectivity(TM) (ICC) technology.

ICC enables the USB 2.0 protocol, which is now standard in billions of electronic devices, to be delivered over short distances consuming a fraction of the power of a traditional USB 2.0 analog interface while retaining 100 percent software compatibility with an analog USB 2.0 connection. The High Speed Interconnect (HSIC) specification (an addendum to the USB 2.0 specification) incorporates ICC technology. Where applicable, such as in portable applications, the ICC technology dramatically decreases power consumption and silicon area compared to an analog USB 2.0 interface.

Under its ICC license with SMSC, AMD can develop devices that are designed to be compliant with the HSIC specification for USB 2.0 host applications.

About SMSC's ICC Technology

SMSC's ICC technology is described in U.S. Patent No. 7,702,832, which was issued to SMSC on April 20, 2010. Additional related patent applications have been filed by SMSC in the United States and other countries. As provided for in the appropriate agreements, USB 2.0 promoters and companies that have timely signed both the USB 2.0 Adopters Agreement and a related HSIC amendment letter may license SMSC's ICC technology patents under reasonable and non-discriminatory (RAND) terms. Further, SMSC's ICC technology is now available to the industry at large through individually negotiated patent licenses from SMSC.
