LSM6DSV16XTR is a 6-axis Inertial Measurement Unit (IMU) manufactured by STMicroelectronics (ST).

# Key Core Parameters

## 1. Basic Physical & Electrical Parameters

- Package: LGA-14L, dimensions 2.5mm × 3.0mm × 0.86mm, ultra-small SMD package

- Supply Voltage: Analog main supply 1.71~3.6V; independent I/O supply 1.08~3.6V

- Operating Temperature: -40℃ ~ +85℃ (commercial grade with general industrial temperature range)

- Communication Interfaces: I2C, SPI, high-speed I3C 1.1 interface (standard configuration for high-end devices)

- FIFO Buffer: 4.5KB data buffer to reduce MCU resource consumption

## 2. Sensing Full Scale & Accuracy

### 3-axis Accelerometer

- Selectable full scales: ±2g / ±4g / ±8g / ±16g

- Noise: 60 µg/√Hz (ultra-low noise for more stable attitude measurement)

### 3-axis Gyroscope

- Selectable full scales: ±125/250/500/1000/2000/±4000 dps (ultra-wide angular velocity range)

- Noise: 2.8 mdps/√Hz, zero-rate bias stability: 3 dph

- Maximum Output Data Rate (ODR): 6.66kHz (top-tier refresh rate in the industry)

## 3. Exclusive Core Features (Key Selling Points for Sales)

1. Triple-Core Independent Architecture (UI + OIS + EIS)

Three independent computing cores separately handle device UI attitude, camera Optical Image Stabilization (OIS) and Electronic Image Stabilization (EIS) without mutual interference. It is the core solution specially designed for main camera stabilization in smartphones.

2. On-board AI Computing Power

- MLC 2.0 Machine Learning Core: Enables on-device motion recognition and attitude judgment without heavy computation load on the main controller MCU

- 8-channel FSM (Finite State Machine): Customizable interrupt triggers for motion events (free fall, shake, tilt, step counting, etc.)

3. Qvar Charge Sensing Technology

External electrodes support touch interactions including single tap, double tap, swipe and long press. Widely applied in TWS earbud tap control, wearable device gesture recognition, eliminating the need for a separate dedicated touch IC.

4. Power Consumption

Typical current: 0.65mA under synchronous high-performance operation. Supports always-on low-power detection to extend the battery life of lithium-powered devices.
