LIS35DE

LIS35DE MEMS motion sensor 3-axis - ±2g/±8g smart digital output “piccolo” accelerometer Feature ■ 2.16 V to 3.6 V supply voltage ■ 1.8V compatible IOs ■ < 1 mW power consumption ■ ±2g/±8g dynamically selectable full-scale ■ I2C/SPI digital output interface ■ Programmable multiple interrupt generator ■ Click and double click recognition ■ Embedded high pass filter ■ 10000g high shock survivability ■ ECOPACK® RoHS and “Green” compliant (see Section 8) Applications ■ Free-fall detection ■ Motion activated functions ■ Gaming and virtual reality input devices ■ Vibration monitoring and compensation Description 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 LGA14 (3x5x0.9mm) 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 leas...
