LIS3DSH: 3-axis digital output accelerometer
Introduction
This document is intended to provide information on the use of and application hints related
to ST’s LIS3DSH 3-axial digital accelerometer.
The LIS3DSH is an ultra-low-power high-performance 3-axis linear accelerometer
belonging to the “nano” family.
It has dynamically user-selectable full scales of ±2g/±4g/±6g/±8g/±16g and is capable of
measuring accelerations with output data rates from 3.125 Hz to 1.6 kHz.
The self-test capability allows the user to check the functioning of the sensor in the final
application.
The LIS3DSH has an integrated first-in, first-out (FIFO) buffer allowing the user to store data
in order to limit intervention by the host processor.
The device can be configured to generate interrupt signals activated by user-defined motion
patterns. To do this, two embedded finite state machines can be programmed independently
for motion detection. Each state machine has 16 states.
The LIS3DSH is available in a small thin plastic land grid array package (LGA), and it is
guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
