LSM6DSM iNEMO inertial module: always-on 3D accelerometer and 3D gyroscope Datasheet - production data Description The LSM6DSM is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope LGA-14L performing at 0.65 mA in high-performance mode and (2.5 x 3 x 0.83 mm) typ. enabling always-on low-power features for an optimal motion experience for the consumer. The LSM6DSM supports main OS requirements, Features offering real, virtual and batch sensors with 4 kbyte for Always-on experience with low power dynamic data batching. consumption for both accelerometer and gyroscope STs family of MEMS sensor modules leverages the Power consumption: 0.4 mA in combo normal mode robust and mature manufacturing processes already and 0.65 mA in combo high-performance mode used for the production of micromachined Smart FIFO up to 4 kbyte based on features set accelerometers and gyroscopes. Android M compliant The various sensing elements are manufactured using specialized micromachining processes, while the IC Auxiliary SPI for OIS data output for gyroscope and interfaces are developed using CMOS technology that accelerometer allows the design of a dedicated circuit which is Hard, soft ironing for external magnetic sensor trimmed to better match the characteristics of the corrections sensing element. 2/4/8/16 g full scale The LSM6DSM has a full-scale acceleration range of 125/250/500/1000/2000 dps full scale 2/4/8/16 g and an angular rate range of Analog supply voltage: 1.71 V to 3.6 V 125/250/500/1000/2000 dps. 2 SPI & I C serial interface with main processor data The LSM6DSM fully supports EIS and OIS applications synchronization as the module includes a dedicated configurable signal Dedicated gyroscope low-pass filters for UI and OIS processing path for OIS and auxiliary SPI configurable applications for both the gyroscope and accelerometer. Smart embedded functions: pedometer, step High robustness to mechanical shock makes the detector and step counter, significant motion and tilt LSM6DSM the preferred choice of system designers for Standard interrupts: free-fall, wakeup, 6D/4D the creation and manufacturing of reliable products. orientation, click and double-click The LSM6DSM is available in a plastic land grid array Embedded temperature sensor (LGA) package.
