The MPU-6100/MPU-6150? family of parts are the world’s first and only 6-axis MotionTracking devices designed for the low power, low cost, and high performance requirements of smart-TV, set top box, and gaming console remote control applications.
The MPU-6150 incorporates InvenSense’s MotionFusion? and run-time calibration firmware that enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices in motion-enabled products, and guarantees that sensor fusion algorithms and calibration procedures deliver optimal performance for consumers.
Motion interface is rapidly becoming a key function in many consumer electronics devices including smartphones, tablets, gaming consoles, and smart-TVs as it provides an intuitive way for consumers to interact with electronic devices by tracking motion in free space and delivering these motions as input commands. Traditional multi-button-based remote controls are difficult to use when browsing and selecting content on a smart-TV, while touchpads and keyboards can be expensive and difficult to maintain and use in the living room environment. The MPU-6150 with MotionFusion and run-time calibration firmware enables consumer electronics manufacturers to commercialize cost effective motion-based remote controls that enable a more intuitive motion interface for smart-TVs, set top boxes, and gaming platforms.
The devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor? (DMP?) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I²C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000? family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards.
The InvenSense MotionApps? Platform that comes with the MPU-6150 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development.
For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2 g , ±4 g , ±8 g , and ±16 g .
The MPU-6100 family is comprised two parts with features summarized in the table below. Both parts feature an industry-leading 6-axis supply current of 3.8mA. To save space, the package size of the devices has been driven down to a revolutionary footprint of 4x4x0.9mm (QFN). Additional features include an embedded temperature sensor and an on-chip oscillator with ±1% variation over the operating temperature range.
