SigmaTel Imaging Systems Group Gains Momentum at CES 2007.

Digital photo frames and printer design wins continue to ramp up 

LAS VEGAS -- SigmaTel, Inc. (NASDAQ:SGTL), a leader in mixed-signal multimedia semiconductors, announced today the introduction of a wireless digital photo frame, Sharp multifunction printer and a Dye-Sub Photo Printer reference platform.

The wireless digital photo frame enables users to send and share photos by simply using emails and RSS photo feeds. This innovative product, created by PF Digital Inc. using SigmaTel technology, connects to the Internet via a home Wi-Fi network and receives photos sent by users from anywhere in the world via emails and RSS feeds. In addition to its networked frame feature, it also supports photo viewing locally from a on-board card reader. eStarling Frame is available today through Thinkgeek. (www.thinkgeek.com)

SigmaTel is demonstrating Wireless Digital Photo Frame technology supporting Microsoft's Windows Media Connect at CES. This innovative technology allows the Photo Frame to become a connected Digital Media Renderer, streaming images and other media from a Microsoft Windows XP or Vista compatible PC that supports Windows Media Connect. This is part of SigmaTel's strategy of promoting connected media devices across all product categories, and is a great way to share images and other media within the home. This technology will be available for SigmaTel Photo Frame development partners in Q1'07 as part of our Software Development Kit (SDK).

Sharp Electronics, a leader in electronic products, has announced their new models of their Multifunctional Facsimile "MIRAKURU (Miracle)", UX-MF60CL/CW, UX-MF50CL/CW, UX-MF25CL/CW. This innovative product uses SigmaTel technology, and enables color LCD, network printing, easy transfer of photos from cell phones, and "Fax to Email" -- an industry-first feature used for sending received faxes directly to an email address.

"We worked with Sharp to launch the Sharp MIRAKURU multifunction printers in Japan in October," said Phil Pompa, interim chief executive officer. "SigmaTel's goal is to add value to our customer's end products, leading the consumer electronics market in features and capabilities. SigmaTel enabled Sharp's customers to print, scan, and convert faxes to email using the broadband capability of the printer. Photos can be printed from memory cards, digital cameras or from mobile phones."

Photo Printers are compact multimedia devices that allow consumers to easily print high quality photographs from cameras and other imaging devices. SigmaTel offers low-cost controller solutions for both Inkjet-based and Dye-Sublimation-based Photo Printers. SigmaTel-based products support many advanced features such as direct print from memory cards and digital cameras, graphic LCD displays, and wireless connectivity options that provide flexible image transfer to the printer.

SigmaTel is now offering a complete solution for Photo Printers that allows our partners to develop market leading products and meet demanding time-to-market requirements. Our Photo Printer Evaluation Kit includes a Dye-Sub Photo Printer hardware reference platform that operates with an off-the-shelf Photo Printer.
