Overview
The LIS2DS12TR is an ultra-low-power, high-performance 3-axis 'pico' accelerometer produced by STMicroelectronics. It belongs to the 'pico' family, leveraging robust and mature manufacturing processes used for micromachined accelerometers. This accelerometer is designed for high accuracy and low power consumption, making it suitable for a wide range of applications. It features user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, and can measure accelerations with output data rates from 1 Hz to 6400 Hz. The device includes an integrated 256-level FIFO buffer and embedded self-test capability, enhancing its functionality and reliability.
