Integrated MEMS inertial module up their game
Designed for augmented reality (AR), virtual reality (VR) and tracking applications, STMicroelectronics has designed the LSM6DSR inertial module for next-generation gaming, industrial, and sports applications.
The LSM6DSR combines high stability with digital features, low power consumption, and small size for head-mounted displays, wearable trackers, smartphones, robotics, and drones.
The MEMS system in package (SiP) contains a three-axis digital accelerometer and a three-axis digital gyroscope with an extended, full-scale angular rate of 4,000 degrees per second for fast-moving gaming and sports applications. The module complies with major mobile OS and supports synchronisation for sensors (S4S) to be compatible with popular mobile platforms. It provides real, virtual, and batch sensing, with a 9kbyte FIFO featuring compression for dynamic data batching.
In addition to VR for gaming and AR for smartphones, the LSM6DSR has native advanced pedometer, step-detector and step-counter functions and significant-motion and tilt detection to ensure accurate activity recognition. It can be used in sensor-hub and IoT devices, indoor navigation, and optical image stabilisation (OIS) for drone-mounted cameras.
Enhanced mechanical design minimises bias and offset drift and temperature-related parameter change, to enhance stability, says ST. As well as long-term consistency, this saves the host system from running complex recalibration, reducing power consumption and maximising application performance, adds the company.
The LSM6DSR is in production now in a 2.5 x 3.0 x 0.83mm 14-pin plastic LGA package.
