STMicroelectronics LSM6DSVTR

Overview

LSM6DSVTR from STMicroelectronics is a 6-axis inertial measurement unit (IMU) integrating a 3-axis digital accelerometer and 3-axis digital gyroscope in a single LGA-14L package (2.5 mm × 3.0 mm × 0.83 mm). It delivers triple-channel architecture for independent UI, OIS, and EIS data processing with ±2/±4/±8/±16 g accelerometer full scale, ±125–±4000 dps gyroscope full scale, and 0.65 mA power consumption in combo high-performance mode - enabling motion-aware smartphone camera stabilization and AR/VR gesture tracking.

For engineers reviewing the LSM6DSVTR datasheet, LSM6DSVTR pinout, LSM6DSVTR application, or LSM6DSVTR equivalent, key selection considerations include its MIPI I3C® v1.1 interface support, auxiliary SPI for OIS data at 7.68 kHz, embedded finite state machine (FSM) running at 960 Hz, sensor fusion low-power (SFLP) quaternion output, and Android-compliant pedometer/tilt/significant motion detection blocks.

Technical Context

The LSM6DSVTR implements three dedicated hardware data paths: Channel 1 for UI motion tracking (I²C/SPI/I3C®), Channel 2 for OIS (auxiliary SPI at 7.68 kHz with ±2 g / ±125–±2000 dps configurable FS), and Channel 3 for enhanced EIS (freerun/FIFO with dedicated timestamping and compression). Each channel supports independent ODR, filtering, and full-scale settings.

It embeds a programmable finite state machine (up to 8 concurrent FSMs) for real-time motion pattern recognition (e.g., glance, shake, wrist tilt), adaptive self-configuration (ASC) for host-free register reprogramming upon motion detection, and a sensor fusion low-power (SFLP) block generating game rotation vector (quaternion), gravity vector, and gyroscope bias - all operating autonomously without host CPU intervention.

Key Specifications

Pinout & Package

LSM6DSVTR is housed in a compact 14-pin LGA package (2.5 mm × 3.0 mm × 0.83 mm) with exposed pad for thermal performance and RoHS/ECOPACK compliance. Pin functions are mode-configurable across I²C/SPI/I3C® slave, master I²C (sensor hub), and auxiliary SPI (OIS) operation.

FAQ

What is the maximum output data rate supported by the LSM6DSVTR for OIS applications?

The LSM6DSVTR supports a dedicated auxiliary SPI interface for OIS data output at 7.68 kHz - delivering synchronized accelerometer and gyroscope samples with independent full-scale configuration (±2 g / ±125–±2000 dps). This rate is fixed for the auxiliary channel and does not depend on primary interface ODR settings.

How does the adaptive self-configuration (ASC) feature operate without host processor involvement?

ASC allows the embedded finite state machine (FSM) to autonomously rewrite device registers (e.g., ODR, FS, filter coefficients) using the SETR command upon detecting predefined motion patterns. The FSM accesses registers exclusively - no arbitration with the host - enabling real-time reconfiguration (e.g., switching to high-OIS mode when camera app launches) without CPU wake-up or firmware intervention.

Does the LSM6DSVTR support MIPI I3C® v1.1 in both controller and target roles?

The LSM6DSVTR operates exclusively as an I3C® target (slave) device - it supports I3C® v1.1 features including dynamic address assignment, in-band interrupt, and HDR modes, but cannot act as an I3C® controller. Its primary serial interface is configurable as I²C, SPI, or I3C® target, while auxiliary SPI handles OIS data separately.

What is the accuracy of the embedded sensor fusion low-power (SFLP) quaternion output?

The SFLP block delivers game rotation vector (quaternion) with 0.5° static yaw accuracy over 5 minutes, 0.5° pitch/roll accuracy under low-dynamic conditions, and stabilizes orientation within 0.7 seconds. Calibration completes in 0.8 seconds, and accuracy is maintained across –40°C to +85°C without host recalibration.
