iNEMO inertial module: 3D accelerometer and 3D gyroscope




The LSM6DS3H is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 1.1 mA (up to 1.6 kHz ODR) in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer.

The LSM6DS3H supports main OS requirements, offering real, virtual and batch sensors with 4 kbyte FIFO + flexible 4 kbyte (FIFO or programmable) for dynamic data batching.

The LSM6DS3H gyroscope supports both OIS/EIS applications. The device can be connected to the camera module through a dedicated auxiliary SPI (Mode 3) while flexibility for the primary interface is available (I2C/SPI).

ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes.

The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.

 

The LSM6DS3H has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±245/±500/±1000/±2000 dps.

High robustness to mechanical shock makes the LSM6DS3H the preferred choice of system designers for the creation and manufacturing of reliable products.

The LSM6DS3H is available in a plastic land grid array (LGA) package.
