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 KXTF9's Directional Tap/Double-TapTM detection feature recognizes singletap and double-tap input and reports the acceleration axis and direction from which each tap originated, enabling up to 12, user-defined, function commands. Its active/inactive algorithm reports changes in a device's motion state, either moving (active) or not moving (inactive), and the orientationdetection feature reports changes in landscape, portrait, face-up, and facedown conditions. A highly-manufacturable product with consistent product performance across use conditions, the KXTF9 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. The sense element design utilizes common mode cancellation to decrease errors from process variation and environmental stress. An ASIC, using a standard CMOS manufacturing process, detects and transforms capacitance changes into an analog voltage, which is proportional to acceleration. Analog signals are further processed into digital signals and within embedded digital algorithms. The device communicates to the system via I 2C bus interface. 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.
