World's First Dual Axis Mems Gyroscope

World's First Dual Axis Mems Gyroscope for 3D Remote Controls and PC Mice.

The IXZ™-500 and IXZ™-650 Gyros released by InvenSense enable single-chip in-plane sensing of Pitch and Yaw and are the world’s first dual-axis microelectromechanical systems (MEMS) gyroscopes to be specifically developed for 3D remote control (TV, home theatre, set top box) and next-generation PC mouse applications.

The IXZ™ family of dual axis MEMS gyros represents the world’s first and only single-chip integrated pitch and yaw (X- and Z-axis) motion processing products that meet the in-plane mounting requirements for both conventional as well as new generations of slim profile remote controls.

The IXZ-family addresses the key performance parameters of remote control application, including low-noise of 0.015°/s/√Hz, an integrated temperature sensor that provides temperature compensated bias adjustment and, thanks to a unique design, high cross-axis isolation.  InvenSense MEMS gyroscopes set the industry’s highest benchmark for robustness supporting 10,000g shock tolerance. By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS wafers with companion CMOS electronics through wafer level bonding, InvenSense has driven the IXZ-family package size down to a small footprint of 4x5x1.2mm (QFN), while providing the highest performance, lowest noise, and the lowest cost semiconductor packaging.

IXZ-500
Designed for audio/video (A/V) remote controls with 3D pointing functionality, the IXZ-500 features a primary output with a full scale range of up to ±500°/second with a ±110°/second internal secondary gain stage output to track slower motions for precise cursor pointing applications. 

IXZ-650
The IXZ-650 targets digital TV and IPTV remote controls with its ±2,000°/second primary output to track the widest dynamic range of physical motions and a ±440°/second internal secondary gain stage output for on-screen pointing applications.

Background
According to Steve Nasiri, CEO and founder of InvenSense, the rapidly approaching transition to digital TV broadcasting and the increasing quantity of downloadable multimedia content, such as TV shows, movies, music and shopping is driving the need for a more intuitive user interface for navigation and selection - from the desk, on the sofa or across the room:  “Motion processing, enabled by our IXZ technology, has led to a new class of 3D remote controls with PC mouse navigation capability enabling users to perform in one motion what would typically require six to ten mechanical button clicks”, Nasiri said. “Typically this allows a single-handed motion to quickly scroll through lists of movie titles or change volume by simply tilting the remote to the desired setting. As more content becomes available, these 3D remote controls include a wide full scale range necessary to support the fast and complex hand movements for TV-based interactive multimedia entertainment while also supporting the exacting requirements of cursor control for menu selection”.

Current dual-axis MEMS gyros based on pitch and roll (X- and Y-axis), were designed for digital camera image stabilization. These gyros are unable to meet the requirements of designers of next-generation remote controls, compelling engineers to compromise by mounting these devices on a daughter board perpendicular to the main board, resulting in an additional height requirement and a manufacturing cost unacceptable to cost sensitive remote control markets.”
