SigmaTel, Inc. (NASDAQ: SGTL), a leader in mixed-signal multimedia semiconductors, today announced that its portable audio System-on-Chip (SoC) solution is the magic powering the new Disney Mix Stick Player. Powered by the SigmaTel STMP35XX, the Disney Mix Stick plays MP3 and WMA audio files and can store both data and music files. The Mix Stick Player has 128 MB of built in memory, enough to hold about 60 songs, with the option to increase storage capacity to 1 GB or about 500 songs with an add-on memory card.

"SigmaTel is committed to providing technology to its customers that allows them to extend their brand to new markets and to offer portable digital audio products at competitive price points without sacrificing device functionality and audio quality," said Michael Wodopian, senior vice president, Portable System on Chip Group at SigmaTel. "The Disney Mix Stick Player is a perfect example of how global brands can utilize SigmaTel's products to develop stylish and cool digital audio products that appeal to their target markets and extends their brand to new audiences."

SigmaTel's portable digital audio solutions provide the required technology for highly recognized, global companies like Disney to extend their brand to new markets and audiences with portable digital audio devices like the Mix Stick Player. Through patented semiconductor and software solutions, SigmaTel's product integration and support allows customers to develop devices with the longest battery life, smallest form factors and lowest system design costs in the market.

"Kids want real MP3 players with all the same functionality that they see in their siblings or parents devices and the SigmaTel solution allowed Disney to deliver that functionality at a very reasonable price point," said Chris Heatherly, vice president of Disney Electronics. "SigmaTel is the gold standard platform for developing portable digital audio players and its solution was the best choice for developing and bringing the Disney Mix Stick to mainstream consumers."

Launched on September 29, 2005 the Disney Mix Stick Player is easily portable and creatively designed for young children and tweens and provides up to 8-hours of continuous music playback. Digital music can be downloaded onto the Mix Stick Player using standard music downloading software or children can listen to their favorite music without having to have a PC using a Disney Mix Clip. The Disney Mix Stick Players are available in four models and include stereo earbuds, rechargeable lithium battery, lanyard with safety release and Microsoft Windows(R) Media software. Disney also offers the Disney Jam Stand allowing kids to play music with hi-fi stereo sound from their Disney Mix Stick player while re-charging its battery.

SigmaTel's portable audio SoC solutions provide high quality audio playback for portable devices such as MP3 players, language learners, and jukeboxes. The company's solutions offer market-leading benefits, including as much as a 30% lower bill of material costs, Hi-Speed USB 2.0, 50 hours of battery life on a single AA battery and incredibly small form factor designs as small as 14.5 square cm. With flexible software support and upgrade options, the SigmaTel SoC solution offers support for MP3 and WMA audio format algorithms as well as security in WMA DRM.
