LIS2DH12: MEMS digital output motion sensor
ultra-low-power high-performance 3-axis "nano" accelerometer
Introduction
This document describes the low-voltage 3-axis digital output linear MEMS accelerometer provided in
an LGA package.
The LIS2DH12 is an ultra-low-power high-performance 3-axis linear accelerometer belonging to the
“nano” family, with a digital I
2
C/SPI serial interface standard output.
The device features ultra-low-power operational modes that allow advanced power saving and smart
sleep-to-wake-up and return-to-sleep functions.
The LIS2DH12 has dynamic user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of
measuring accelerations with output data rates from 1 Hz to 5 kHz.
The device may be configured to generate interrupt signals using an independent inertial wake-up/free-
fall event as well as by the position of the device itself. Thresholds and timing of the interrupt generator
are programmable by the end user on the fly.
Automatic programmable sleep-to-wakeup and return-to-sleep functions are also available for enhanced
power saving.
The LIS2DH12 has an integrated 32-level first-in first-out (FIFO) buffer allowing the user to store data in
order to limit intervention by the host processor.
The LIS2DH12 is available in a small thin plastic land grid array package (LGA) and is guaranteed to
operate over an extended temperature range from -40 °C to +85 °C.
The ultra-small size and weight of the SMD package make it an ideal choice for handheld portable
applications such as smartphones, IoT connected devices, and wearables, or any other application
where reduced package size and weight are required.
