STMicroelectronics LSM6DSV iNEMO™ Inertial Module

STMicroelectronics LSM6DSV iNEMO™ Inertial Module is a system-in-package featuring a 3-axis digital gyroscope and a 3-axis digital accelerometer. It has a triple core for processing acceleration and angular rate data on three separate channels with dedicated configuration, filtering, and processing. The LSM6DSV boosts performance at 0.65mA in high-performance mode and enables always-on low-power features for an optimal motion experience for the consumer. The device embeds advanced dedicated features such as a finite state machine and data filtering for OIS, EIS, and motion processing.

The LSM6DSV supports main OS requirements, offering real, virtual, and batch mode sensors. In addition, the LSM6DSV can efficiently run the sensor-related features specified in Android, saving power and enabling faster reaction time. In particular, the LSM6DSV has been designed to implement hardware features such as significant motion detection, stationary/motion detection, tilt, pedometer functions, and timestamping to support the data acquisition of external sensors.

The LSM6DSV offers hardware flexibility to connect the pins with different mode connections to external sensors to expand functionalities such as adding a sensor hub, auxiliary SPI, etc. The LSM6DSV offers advanced design flexibility for OIS and EIS applications. Both channels have a dedicated processing path with independent filtering and enhanced EIS channel gyroscope data that are read over the primary interfaces I²C/ MIPI I3C® v1.1/SPI.

The STMicroelectronics LSM6DSV is available in a small plastic land grid array (LGA) package of 2.5mm x 3.0mm x 0.83 mm to address ultra-compact solutions.
