LIS2DE12TR Description

The LIS2DE12TR  is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I2C  /SPI serial interface standard output. The LIS2DE12TR  has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.

LIS2DE12 Electrical Connections

The device core is supplied through the Vdd line while the I/O pads are supplied through the Vdd  _IO line. Power supply decoupling capacitors (100 nF ceramic, 10 μF aluminium) should be placed as near as possible to pin 9 of the device (common design practice). All the voltage and ground supplies must be present at the same time to have the proper behaviour of the IC (refer to Figure). It is possible to remove Vdd while maintaining Vdd  _IO without blocking the communication bus, in this condition the measurement chain is powered off.
The functionality of the device and the measured acceleration data is selectable and accessible through the I2C  or SPI  interfaces. When using the I2C, CS must be tied high.
The functions, the threshold and the timing of the two interrupt pins (INT1 and INT2) can be completely programmed by the user through the I2C /SPI interface.
