New MEMS Inertial Module from STMicroelectronics


The LSM6DSR features an angular rate of 4000 degrees per second for fast-moving virtual reality games


STMicroelectronics have released a new MEMS Inertial Module designed for the next generation of Virtual Reality (VR) headsets and gaming, as well as superior Augmented Reality (AR) for motion sensing in new smartphones. The LSM6DSR inertial module combines high stability with advanced digital features, low power consumption, and small size for head-mounted displays, wearable trackers, smartphones, robotics, and drones.

Click for Larger Image - New MEMS Inertial Module from STMicroelectronics The LSM6DSR MEMS System-in-Package contains a 3-axis digital accelerometer and a 3-axis digital gyroscope with a specially extended full-scale angular rate of 4000 degrees per second for fast-moving gaming and sports applications. Compliant with major mobile OSes, and supporting S4S Synchronization for Sensors, the LSM6DSR is compatible with popular mobile platforms and provides real, virtual, and batch sensing, with a 9Kbyte FIFO featuring compression for dynamic data batching.

To power more immersive virtual reality (VR) experiences in gaming and professional applications, the LSM6DSR also enables superior augmented reality (AR) on new smartphones. In addition, native advanced pedometer, step-detector and step-counter functions, and significant-motion and tilt detection ensure accurate and efficient activity recognition. On top of this, the LSM6DSR is ideal for use in sensor-hub and IoT devices, indoor navigation, and optical image stabilization (OIS) for drone-mounted cameras.

Superior stability is assured through enhanced mechanical design that minimizes bias and offset drift and temperature-related parameter change. This ensures long-term consistency and saves the host system from running complex recalibration thereby reducing power consumption and maximizing application performance.
