Overview
The LIS2DE12TR is an ultra-low-power, high-performance three-axis linear accelerometer produced by STMicroelectronics. It belongs to the 'femto' family and features a digital I2C/SPI serial interface for output. This accelerometer is capable of measuring accelerations with user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, and it supports output data rates from 1 Hz to 5.3 kHz. The device includes a self-test capability to verify its functionality in the final application and can generate interrupt signals for detecting inertial wake-up/free-fall events and device position. It is packaged in a small thin plastic land grid array (LGA) and operates over an extended temperature range from -40 °C to +85 °C.
