LSM6DS3H iNEMO inertial module: always-on 3D accelerometer and 3D gyroscope Datasheet - production data Description The LSM6DS3H is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope LGA-14L performing at 1.1 mA (up to 1.6 kHz ODR) in high- (2.5 x 3 x 0.83 mm) typ. performance mode and enabling always-on low-power features for an optimal motion experience for the consumer. Features The LSM6DS3H supports main OS requirements, offering real, virtual and batch sensors with 4 kbyte Power consumption: 0.85 mA in combo normal FIFO + flexible 4 kbyte (FIFO or programmable) for mode and 1.1 mA in combo high-performance mode dynamic data batching. up to 1.6 kHz. Always-on experience with low power The LSM6DS3H gyroscope supports both OIS/EIS consumption for both accelerometer and gyroscope applications. The device can be connected to the 2 camera module through a dedicated auxiliary SPI Interface flexibility: selectable SPI (3/4-wire) or I C (Mode 3) while flexibility for the primary interface is with the main processor 2 available (I C/SPI). Auxiliary SPI (3-wire) to support OIS applications STs family of MEMS sensor modules leverages the EIS/OIS support robust and mature manufacturing processes already Accelerometer ODR up to 6.66 kHz used for the production of micromachined Gyroscope ODR up to 3.33 kHz accelerometers and gyroscopes. Smart FIFO The various sensing elements are manufactured using 2/4/8/16 g full scale specialized micromachining processes, while the IC interfaces are developed using CMOS technology that 125/250/500/1000/2000 dps full scale allows the design of a dedicated circuit which is Analog supply voltage: 1.71 V to 3.6 V trimmed to better match the characteristics of the Independent IOs supply (1.62 V) sensing element. Compact footprint, 2.5 mm x 3 mm x 0.83 mm The LSM6DS3H has a full-scale acceleration range of 2 SPI/I C serial interface data synchronization feature 2/4/8/16 g and an angular rate range of 125/250/500/1000/2000 dps. Embedded temperature sensor ECOPACK , RoHS and Green compliant High robustness to mechanical shock makes the LSM6DS3H the preferred choice of system designers for the creation and manufacturing of reliable products. Applications The LSM6DS3H is available in a plastic land grid array EIS and OIS for camera applications (LGA) package. Collecting sensor data Motion tracking and gesture detection Table 1.
