KXTE9 Series Accelerometers and Inclinometers FEATURES MARKETS Ultra-Small Package - 3x3x0.9mm LGA Activity-monitoring Algorithm (Active/Inactive) Device Orientation Detection Algorithm Digital I2C Communication Interface Very Low Power Consumption (30A full operation) Lead-free Solderability Excellent Temperature Performance High Shock Survivability User-selectable Output Data Rate Factory Programmable Offset and Sensitivity Self-test Function PROPRIETARY TECHNOLOGY APPLICATIONS Mobile Phones and Mobile Internet Devices Screen Rotation Gesture Recognition User Interface Power Management Activity Monitoring Game Controllers and Computer Peripherals Inclination and Tilt Sensing User Interface Power Management Activity Monitoring Sports Diagnostic Equipment Static and Dynamic Acceleration Activity Monitoring These high-performance silicon micromachined linear accelerometers and inclinometers consist of a sensor element and an ASIC packaged in a 3x3x0.9mm Land Grid Array (LGA). 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 KXTE9's 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 parameters, the screen-rotation algorithm can be optimized for an intuitive user experience. In addition to orientation detection, the KXTE9 features an activity-monitoring function. This function reports changes in a device's motion 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 voltage, 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 and is accessed via an inter-interated circuit (I2C). 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.
