Freescale Semiconductor has unveiled the future of the smartbook category with a tablet reference design featuring a 7-inch touch screen with up to four times the viewing area of a typical smartphone and based on a form factor that is approximately one-third the size and volume of today’s typical netbook.
The solution is intended to enable a second generation of smartbook products with prices less than $200 and featuring form factors that fully leverage the power, performance and functionality advantages of advanced ARM processor technology. It is designed to provide instant-on functionality, persistent connectivity and all-day battery life. The tablet will be demonstrated at the 2010 Consumer Electronics Show running both the Android and Linux operating systems.
Designed to help OEMs jump-start creation of smartbook tablets, the solution is based on Freescale’s highly integrated i.MX515 processor incorporating ARM Cortex-A8 technology. It also includes Freescale’s MC13892 power management IC, SGTL5000 audio codec and MMA8450Q 3-axis accelerometer. End products based on the design could hit retail shelves as soon as the summer of 2010.
The design is the first platform in Freescale’s Smart Application Blueprint for Rapid Engineering (SABRE) series. The SABRE tablet platform for smartbooks incorporates feedback from a recently completed end-user research study conducted in conjunction with Savannah College of Art and Design’s prestigious Industrial Design program.
The Freescale tablet includes Wi-Fi and Bluetooth® wireless connectivity, and also features a 3D desktop framework with touch screen/QWERTY keyboard support. 3G modem and RF4CE protocol options are available. The tablet’s modular approach to 3G connectivity lets systems designers select carrier-specific air interfaces appropriate for different regions. Modules can be pre-certified by carriers and selected to match a range of features and performance targets. This method makes it easy to migrate quickly to new modem technologies as they are introduced.
