World’s Lowest Power Consumption Accelerometer with Embedded Algorithms


Ithaca, New York, November 2008 – Kionix announced today the expansion of its digital-output, tri-axis accelerometer product line with the KXTE9 product series. With embedded algorithms for orientation and activity monitoring, the KXTE9 simplifies the adoption of increasingly-popular, motion-based functionality in consumer electronics while reducing operating power consumption to the world’s lowest levels for such feature-rich products.


“The typical operating current for a fully operational KXTE9 is 30 µA,” said Eric Eisenhut, Vice President for Sales and Marketing. “Kionix has proven to be a leader in enabling applications in mobile products that rely on inertial sensors. This newest innovation takes the historical, industry-expected, current consumption from 200-300 µA down to 30 µA.”


The advanced, orientation-detection feature of the KXTE9 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.  Accordingly, the KXTE9 enables the implementation of screen rotation—such as that found on some high-end mobile phones— into any handheld device. 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). By providing this information to the device, the KXTE9 enables power management, a critical function in today’s mobile devices for prolonging battery life, and other novel motion-based applications.


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 part is RoHS compliant, halogen-free, and delivered in a 3x3x0.9mm LGA package.
