LIS3DHTR Description

The LIS3DHTR is a digital I2C/SPI serial interface standard output, three-axis, ultra-low-power, high-performance accelerometer from the "nano" family. The system has ultra-low power operating modes that enable sophisticated power management and intelligent embedded functionalities.

The LIS3DHTR is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz and has dynamically user-selectable complete scales of ±2g, ±4g, ±8g, and ±16g. The user can test the sensor's performance in the intended application thanks to the self-test feature. Two independent inertial wake-up/free-fall occurrences and the device's position can both be used to configure the device to produce interrupt signals.

End users can dynamically program interrupt generator thresholds and timing. The embedded 32-level first-in, first-out (FIFO) buffer on the LIS3DHTR enables users to store data and limit host processor involvement. The LIS3DHTR can work across a wide temperature range, from -40 °C to +85 °C, and is offered in a tiny thin plastic land grid array package (LGA).
