LIS302DL
MEMS motion sensor 3-axis - 2g/ 8g smart digital output "piccolo" accelerometer
Feature

2.16V to 3.6V supply voltage 1.8V compatible IOs <1mW 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 Embedded self test 10000g high shock survivability ECOPACK RoHS and "Green" compliant (see Section 9) 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 LIS302DL has dynamically user selectable full scales of 2g/ 8g and it is capable of measuring accelerations with an output data rate of 100Hz or 400Hz. A self-test capability allows the user to check the functioning of the sensor in the final application. 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 th
e three axes. Thresholds and timing of interrupt generators are programmable by the end user on the fly. The LIS302DL is available in plastic Thin Land Grid Array package (TLGA) and it is guaranteed to operate over an extended temperature range from -40 C to +85 C.
LGA-14 (3x5x0.9mm)

Application

Free-Fall detection Motion activated functions Gaming and virtual reality input devices Vibration monitoring and compensation

Description
The LIS302DL is an ultra compact low-power three axes 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 Table 1. Device summary
