    LIS3DHTR LIS3DH Series 3-Axis MEMS Accelerometer


    ±2g/±4g/±8g/±16g Selectable Range x 4mg/√Hz Noise Density — Ultra-Low-Power, High-Performance Digital Accelerometer

     

    LIS3DHTR Product Overview

    The LIS3DHTR is an ultra-low-power, high-performance 3-axis linear accelerometer from STMicroelectronics' LIS3DH Series, designed for the precise electronic measurement of acceleration along three orthogonal axes with digital output and selectable full-scale ranges. The TR variant features a 14-pin VFLGA package (3x3x1 mm) and includes advanced features such as a temperature sensor, FIFO buffer, and embedded motion detection functions.

    Rated for selectable full-scale ranges of ±2g, ±4g, ±8g, and ±16g, it outputs digital acceleration data via I²C/SPI interfaces with 16-bit resolution. Typical sensitivity ranges from 1 mg/digit (±2g) to 0.244 mg/digit (±8g), with low noise spectral density of 4 mg/√Hz . Supply voltage ranges from 1.71 V to 3.6 V. Mass is approximately 0.10 g and operating temperature ranges from -40°C to +85°C . The device integrates a 32-level FIFO buffer, motion detection functions (free-fall, wake-up, 6D/4D orientation), and the ability to synchronize with external sensors via the auxiliary I²C interface.

    LIS3DHTR Key Advantages

    The LIS3DHTR employs a MEMS capacitive sensing element with advanced signal processing, delivering selectable full-scale ranges from ±2g to ±16g while consuming only 2 µA in low-power mode, making it ideal for battery-operated applications. The 16-bit resolution and low noise density of 4 mg/√Hz enable high-precision measurements for a wide range of sensing applications. The 14-pin VFLGA package (3x3x1 mm) accommodates ultra-compact PCB layouts and low profile designs. The integrated 32-level FIFO buffer reduces host processor overhead, while the embedded motion detection functions (free-fall, wake-up, 6D/4D orientation) enable intelligent power management. The auxiliary I²C interface allows synchronization with external sensors, and the autonomous low-power modes minimize system power consumption.

     

    LIS3DHTR Typical Applications

    Motion-activated user interfaces and smart device features
    Tilt sensing and screen rotation detection for smartphones and tablets
    Gaming controllers and gesture recognition systems
    Industrial condition monitoring and vibration analysis
    Wearable health monitors and fitness trackers
    Free-fall detection for hard disk drive protection and portable devices

     

    Why Choose the LIS3DHTR?

    The LIS3DHTR combines selectable ±2g/±4g/±8g/±16g ranges, 16-bit resolution, and ultra-low 2 µA power consumption in a compact 3x3x1 mm VFLGA package with I²C/SPI digital interfaces and embedded motion detection. Manufactured by STMicroelectronics, it delivers stable, accurate, and reliable acceleration measurement for a wide range of consumer, industrial, and IoT applications. The ultra-low power consumption and embedded FIFO buffer offer the distinct advantage of extended battery life and reduced host processor load, while the selectable full-scale ranges and integrated motion detection functions enable flexible system design with minimal external components.
