The sensor element is fabricated from single-crystal silicon with proprietary Deep Reactive Ion Etching (DRIE) processes, and is protected from the environment by a hermetically-sealed silicon cap at the wafer level. The KXTE9s advanced, orientation-detection feature reports changes in landscape, portrait, face-up, and face-down conditions. This sophisticated, embedded algorithm eliminates the need for continuous data collection and complex calculations by a microprocessor. With a few adjustable parame- ters, the screen-rotation algorithm can be optimized for an intuitive user experience. In addition to orientation detection, the KXTE9 features an ac- tivity-monitoring function. This function reports changes in a devices mo- tion state, either moving (active) or not moving (inactive). A highly- manufacturable product with consistent product performance across use conditions, the KXTE9 operates across a supply voltage of 1.8V to 3.6V DC. The sensor element functions on the principle of differential capacitance. Acceleration causes displacement of a silicon structure resulting in a change in capacitance. An ASIC, using a standard CMOS manufacturing process, detects and transforms changes in capacitance into an analog output volt- age, which is proportional to acceleration. The sense element design utilizes common mode cancellation to decrease errors from process variation and environmental stress. The voltage is digitized by an on-board A/D converter 2 and is accessed via an inter-interated circuit (I C). 36 Thornwood Dr. - Ithaca, NY 14850 USA tel: 607-257-1080 - fax: 607-257-1146 - www.kionix.com - info kionix.com Kionix is a registered trademark of Kionix, Inc.
