STMicroelectronics LIS331DLHTR Accelerometer

The LIS331DLHTR is a high-performance, ultra-low-power 3-axis "nano" accelerometer belonging to the "eco-friendly" product line from STMicroelectronics. This compact sensor provides precise acceleration data with a digital I2C/SPI serial interface output, making it a popular choice for mobile applications and various other fields where space constraints and energy efficiency are critical factors.

Featuring a full-scale range of ±2g/±4g/±8g, the LIS331DLHTR can measure accelerations with output data rates from 50 Hz to 1 kHz. It is designed to operate over an extended temperature range from -40°C to +85°C, ensuring reliable performance across diverse environments.

One of the key advantages of this sensor is its embedded intelligence, which includes features such as:

• High-resolution detection of acceleration along all three axes, with 16-bit data output.
• Programmable interrupt generators for free-fall and motion detection, which can be used for advanced system power-saving and user interface functionalities.
• Sleep-to-wakeup function, enabling power conservation between active measurements.

The LIS331DLHTR is housed in a small thin plastic land grid array package (LGA) that is environmentally friendly, lead-free, and compliant with RoHS/REACH regulations. Its small footprint and low profile (3x3x1mm) make it an ideal choice for portable device integration.

Common applications for the LIS331DLHTR include:

• Smartphones and tablets
• Gaming and virtual reality input devices
• Impact recognition and logging systems
• Vibration monitoring and compensation
• Navigation and telematics

STMicroelectronics' commitment to innovation and sustainability is evident in the LIS331DLHTR, offering designers a robust and eco-friendly solution for motion sensing requirements. With its advanced features and versatile application range, this accelerometer is a solid choice for adding reliable motion detection to your next project.
