Business Wire, Feb 6, 2006

AUSTIN, Texas -- SigmaTel Inc. (NASDAQ:SGTL), a leader in mixed-signal multimedia semiconductors, today announced that its portable audio System-on-Chip (SoC) solution powers the SWISSMEMORY(TM) s.beat digital audio player from Swissbit and Victorinox, the makers of the world-renowned Swiss Army Knife. The SWISSMEMORY s.beat series of flash-based digital audio players are available in 1GB and 2GB models. Powered by the SigmaTel STMP3550, the s.beat is an all-in-one digital audio player and USB storage device incorporated into a full-metal Swiss Army Knife.

"SigmaTel's industry-leading solutions provide customers the ability to design and manufacture a wide variety of portable digital media devices offering the latest and best-in-class functionality," said Michael Wodopian, senior vice president, Portable System-on-Chip Group at SigmaTel. "Having a world-renowned brand like Swiss Army and a technology leader like Swissbit using SigmaTel technology underscores our commitment to delivering innovative solutions to the market."

SigmaTel's portable multimedia SoC solutions provide the necessary technology, including software, hardware and third-party application support for companies like Swissbit and Victorinox to develop creative multimedia products that help them extend their brands into new markets. Through patented semiconductor solutions and software, SigmaTel's high level of integration and support allow customers to develop devices offering longest battery life, smallest form factors and lowest system design costs in the market.

The SWISSMEMORY s.beat can store data and music files and plays back MP3, WMA, WAV and OGG Vorbis digital audio files. Providing up to eight hours of playback with a rechargeable lithium polymer battery, the s.beat also has a built-in FM radio with 15 preset channels, the ability to record FM radio onto the device and a voice recorder. The s.beat also provides drag-and-drop functionality, meaning users can plug the device into any USB port and transfer files without the need for special software or a specific device driver.

"The high level of integration and the flexibility of the SigmaTel solutions allowed Swissbit to develop a small form factor, full-featured digital audio player that was small enough to fit inside a Swiss Army Knife," said Dominique Froidevaux, product manager Multi Media at Swissbit. "With the stylish SWISSMEMORY s.beat, we can offer consumers a best-in-class digital audio player that carries the renowned Swiss Army brand."

The s.beat comes with a highly sensitive remote control that includes two earphone connections for parallel listening, high-quality earphones, adjustable rubber arm strap and has a high-contrast backlight LCD. The s.beat is available with the Swiss Army knife tools, including scissors, nail file/screwdriver and blade/knife or an airline-friendly flight version that does not have the tools.

The company's solutions offer market-leading benefits, including as much as a 30% lower bill of material costs, Hi-Speed USB 2.0, up to 70 hours of battery life on a single AA battery and incredibly small form factor designs.
