LSM6DS3 iNEMO inertial module: always-on 3D accelerometer and 3D gyroscope Datasheet - production data Description The LSM6DS3 is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope LGA-14L performing at 1.25 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 LSM6DS3 supports main OS requirements, Power consumption: 0.9 mA in combo normal mode offering real, virtual and batch sensors with 8 kbyte for and 1.25 mA in combo high-performance mode up to dynamic data batching. 1.6 kHz. STs family of MEMS sensor modules leverages the Always-on experience with low power robust and mature manufacturing processes already consumption for both accelerometer and gyroscope used for the production of micromachined Smart FIFO up to 8 kbyte based on features set accelerometers and gyroscopes. Compliant with Android K and L The various sensing elements are manufactured using specialized micromachining processes, while the IC Hard, soft ironing for external magnetic sensor interfaces are developed using CMOS technology that corrections allows the design of a dedicated circuit which is 2/4/8/16 g full scale trimmed to better match the characteristics of the 125/250/500/1000/2000 dps full scale sensing element. Analog supply voltage: 1.71 V to 3.6 V The LSM6DS3 has a full-scale acceleration range of Independent IOs supply (1.62 V) 2/4/8/16 g and an angular rate range of Compact footprint, 2.5 mm x 3 mm x 0.83 mm 125/250/500/1000/2000 dps. 2 SPI/I C serial interface with main processor data High robustness to mechanical shock makes the synchronization feature LSM6DS3 the preferred choice of system designers for the creation and manufacturing of reliable products. Embedded temperature sensor ECOPACK , RoHS and Green compliant The LSM6DS3 is available in a plastic land grid array (LGA) package. Applications Table 1.
