STMicroelectronics LSM6DSV16X 6-Axis IMU Sensor, ±16g Accelerometer + ±4000dps Gyroscope, Embedded ML Core, SPI/I²C/I3C, LGA-14

The LSM6DSV16X supports three primary digital interfaces: a 4-wire SPI bus operating up to 10 MHz, a standard I²C bus up to 1 MHz, and the modern MIPI I3C interface. This flexibility allows seamless integration with a wide range of host microcontrollers, application processors, and system-on-chips (SoCs) in both 3.3V and 1.8V logic environments.

The embedded Machine Learning Core (MLC) is a hardware block within the LSM6DSV16X that executes pre-trained decision tree classifiers directly on the sensor. It processes raw accelerometer and gyroscope data to detect specific motion patterns, gestures, or activities—like wrist flicks, step counting, or device orientation—without requiring constant intervention from the main application processor, significantly saving system power.

The triple-channel architecture provides three independent and simultaneous data output streams from a single sensor. One channel is dedicated to user interface functions (e.g., screen rotation), another for Optical Image Stabilization (OIS) feedback in camera modules, and a third for Electronic Image Stabilization (EIS) algorithms. This eliminates the need for multiple discrete sensors and reduces system complexity.

The sensor's analog and digital core (Vdd) operates from 1.71V to 3.6V. The I/O pins (Vddio) have a separate supply range from 1.08V to 3.6V, allowing the communication interface logic levels to be decoupled from the core voltage. This enables direct connection to both 1.8V and 3.3V host systems without requiring level shifters.
