STMicroelectronics’ new LSM6DSL and LSM6DSM six-axis MEMS inertial modules feature innovative power management, enhanced gyroscope design and energy-efficient data batching.
These features enable the new devices to cut power consumption by as much as 50% compared to that of the current LSM6DS3 and LSM6DS3H modules from ST.
In addition, the latest sensors offer better gyroscope accuracy, enabling them to support enhanced user experiences such as Optical Image Stabilisation (OIS), visual localisation detection and gesture recognition.
Accelerometer-based step detection, step- counting and pedometer functions, as well as tilt and significant-motion detection, are also integrated to make system implementation easier for application developers.
The LSM6DSM includes a dedicated additional processing and serial port for camera OIS. The gyroscope has 40% lower noise and a configurable filter which together boost OIS performance when compared to the LSM6DS3H. Use of a LSM6DSM in place of a discrete OIS sensor not only saves component count and board space, but consumes less than one-sixth the power of alternative designs.
Housed in a 14-pin 2.5mm x 3.0mm x 0.83mm LGA package, the new devices are pin-and-footprint compatible with the LSM6DS3 and LSM6DS3H.
