LSM6DSL / LSM6DSM High-Efficiency 6-Axis MEMS Sens

STMicro’s LSM6DSL and LSM6DSM, with innovative power management, enhanced gyroscope design, and energy-efficient data batching, cut power consumption by as much as 50% over the current state-of-the-art LSM6DS3 and LSM6DS3H devices. Compliance with the most popular and innovative operating systems help developers maximize the value of the personalization and power-saving features of popular mobile platforms. These motion-sensing devices are certified for Google Daydream and Tango, and support immersive virtual and augmented reality on Android mobile devices.

In addition, the latest sensors boost gyroscope accuracy to support enhanced user experiences such as optical image stabilization (OIS), visual localization detection, and gesture recognition, while the accelerometer-driven step detection, step counting, and pedometer, as well as tilt and significant-motion detection, are also integrated to make life easier for handset and application developers.

Of these two modules, the LSM6DSM has a dedicated additional processing and serial port for camera OIS. The gyroscope has 40% lower noise and a configurable filter that together boosts camera-OIS performance from the current-generation device (LSM6DS3H). Compared to solutions that use a discrete OIS sensor, the LSM6DSM not only saves component count and board space, but consumes less than 1/6 the power of the alternative designs.
