SUNNYVALE, USA: InvenSense Inc., the leading solution provider of MotionProcessors for consumer electronics, has released its highly anticipated MPU-6000 product family.
The MPU-6000 is a breakthrough in MEMS motion sensing technology with the integration of 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 sensor fusion algorithms.
With increasing popularity of motion sensors in everyday consumer electronics, pioneered by Nintendo with the Wii console and later by Apple with the iPhone, motion processing is quickly expanding into smart phones, tablets, TV remotes, handheld gaming devices and gaming consoles, digital still and video cameras and many other consumer products.
The MPU-6000 family of MotionProcessors eliminates the challenges associated with selection and integration of many different motion sensors that could require signal conditioning, sensor fusion and factory calibration. It features integrated 9-axis sensor fusion algorithms that utilize an external magnetometer output through its master I2C bus to provide dead reckoning functionality.
The MPU-6000 is offered in the same 4x4x0.9 mm QFN package and the same pinout as the current MPU-3000 product family of integrated 3-axis gyroscopes, making it easy to fit on already space constrained boards. It also offers ease of integration and interface to various application processors through an I2C or SPI bus and its standard MotionProcessing Library (MPL) and APIs.
“InvenSense is developing in parallel of the silicon device, software functions and applications software that will simplify the integration of motion processors into modules and systems, paving the way towards a larger market and wide diffusion of motion processors into consumer electronics.”
Adoption of motion processing functions in smartphones, tablets and many other portable consumer electronic devices is promising to bring a host of new and enhanced functionalities and benefits to consumers including: precise sensing of hand jitter to improve image quality and video stability; GPS dead reckoning for vehicles and indoor pedestrian navigation and new motion-based user interfaces, augmented reality and more immersive gaming experiences to name a few.
However, market adoption has been slow primarily due to a lack of available off-the-shelf solutions that could be adopted quickly and easily by OEMs. Today, developing an integrated motion sensor solution requires using various components offered by many different suppliers, adding signal conditioning, developing proprietary sensor fusion algorithms, processing overhead and resource allocation and understanding the complex IP challenges in this space, all of which adds cost and delays in adoption by end customers.
