Qualcomm has leaked a few more details of its much-debated smartbook and unveiled a line of super-powered chips for smartphones.

Company CEO Paul Jacobs said the Snapdragon-based Lenovo smartbook would be carried by AT&T. Jacobs did not comment on pricing or availability. The announcement at the company’s investor day conference yesterday comes ahead of the device’s official debut at the January 2010 Computer Electronics Show (CES) in Las Vegas.

PC World reports the device has a Linux-based user interface with six widgets, including those for e-mail and Facebook. The smarbook’s battery is mainly used to power the device’s screen. Jacobs also said the device’s screen would support high-definition, but provided no details on its resolution.

Separately, Qualcomm released a new family of high-powered chips for smartphones. The MSM7x30 chip family and Qualcomm’s Snapdragon chipset share the same CPU, Scorpion. The 7×30 also has an 800 MHz to 1 GHz ARM-based processor, supports 720p HD video, a 12-megapixel camera and is compatible with operating systems including Android, Windows Mobile, Brew and Symbian.

“Qualcomm continues to focus on enabling the best possible mobile experiences and this new family of solutions brings an unmatched feature set to the smartphone segment,” said Alex Katouzian, vice president of product management for Qualcomm CDMA Technologies, in a statement. “As the demand for smartphones continues to grow, our innovative technology will enable Qualcomm’s device manufacturing partners to deliver products with greater value than ever before.”

Qualcomm said devices based on the new MSM7x30 chips would be released before year-end 2010.
