STMicroelectronics Introduces Motion Sensor with Machine Learning-LSM6DSOX
Published time: 2019-12-20 09:55:36
STMicroelectronics announced the integration of machine learning technology into its advanced inertial sensors to improve the motion tracking performance and battery life of mobile phones and wearables.
The LSM6DSOX iNEMO sensor integrates a machine learning core that classifies motion data according to known motion patterns and replaces the first stage task of the main processor to handle motion tracking.
This method can save energy and reduce consumption, speed up fitness records, and health monitoring. The speed of running sports applications such as personal navigation and fall detection applications.
Andrea Onetti, vice president of analog, MEMS and sensor products at STMicroelectronics, said: "Machine learning has been used extensively for applications such as social media, financial modeling or autonomous driving to improve the speed and efficiency of pattern recognition.
The LSM6DSOX motion sensor integrates the machine learning ability that enhance the motion tracking performance of smartphones and wearables."
Devices equipped with the STMicroelectronics LSM6DSOX can provide users with a convenient, responsive "always on" experience with no impact on battery life.
Compared with the traditional sensor, the LSM6DSOX adds more memory space and it is equipped with the most advanced high-speed I3C digital interface, which makes the sensor and the main controller have longer interaction interval, shorter connection time and better energy saving effect
The sensor is easy to integrate into mainstream mobile platforms such as Android and iOS, simplifying the flow of consumer, medical and industrial smart devices.
Official description from STMicroelectronics
The LSM6DSOX is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope boosting performance at 0.55 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer.
The LSM6DSOX supports main OS requirements, offering real, virtual and batch sensors with 9 kbytes for dynamic data batching. ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes. The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.
The LSM6DSOX has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±250/±500/±1000/±2000 dps.
The LSM6DSOX fully supports EIS and OIS applications as the module includes a dedicated configurable signal processing path for OIS and auxiliary SPI, configurable for both the gyroscope and accelerometer. The LSM6DSOX OIS can be configured from the Auxiliary SPI and primary interface (SPI / I²C & MIPI I3CSM).
High robustness to mechanical shock makes the LSM6DSOX the preferred choice of system designers for the creation and manufacturing of reliable products. The LSM6DSOX is available in a plastic land grid array (LGA) package.
