Product overview


The LIS35DE is an ultra compact low-power three axis linear accelerometer. It includes a sensing element and an IC interface able to provide the measured acceleration to the external world through I2C/SPI serial interface.

The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.

The IC interface is manufactured using a CMOS process that allows to design a dedicated circuit which is trimmed to better match the sensing element characteristics.

The LIS35DE has dynamically user selectable full scales of ±2g/±8g and it is capable of measuring accelerations with an output data rate of 100 Hz or 400 Hz.

The device may be configured to generate inertial wake-up/free-fall interrupt signals when a programmable acceleration threshold is crossed at least in one of the three axes. Thresholds and timing of interrupt generators are programmable by the end user on the fly.

The LIS35DE is available in plastic Thin Land Grid Array package (TGA) and it is designed to operate over an extended temperature range from -40°C to +85°C.
