LSM6DSMTR

Overview

The LSM6DSMTR is a high-performance 6-axis MEMS Inertial Measurement Unit (IMU) featuring a 3D digital accelerometer and a 3D digital gyroscope. It is designed for always-on applications, drawing as little as 0.4 mA in normal combo mode while offering advanced features like a smart 4 kbyte FIFO and an auxiliary SPI specifically for Optical Image Stabilization (OIS) data.

Why Choose This Part

This IMU offers an exceptional balance of power and performance, operating between 1.71V and 3.6V with a high-performance mode current of only 0.65 mA. It reduces system-level power consumption by offloading motion processing to its internal 4 kbyte FIFO and dedicated hardware features like free-fall and tilt detection.

Applications

Getting Started

Engineers can evaluate this sensor using the STEVAL-MKI189V1 adapter board which plugs into standard DIL24 sockets. Software development is supported through the X-CUBE-MEMS1 expansion for the STM32Cube environment, providing drivers and example code for I2C and SPI communication.
