LSM330DLCTR STMicroelectronics

LSM330DLC iNEMO inertial module: 3D accelerometer and 3D gyroscope Datasheet production data Features Analog supply voltage: 2.4 V to 3.6 V Digital supply voltage IOs: 1.8 V Low power mode Power-down mode LGA-28L (4x5x1.1 mm) 3 independent acceleration channels and 3 angular rate channels The various sensing elements are manufactured using specialized micromachining processes, 2 g/4 g/8 g/16 g dynamically selectable while the IC interfaces are developed using a full scale CMOS technology that allows the design of a 250/500/2000 dps dynamically selectable dedicated circuit which is trimmed to better match full scale the sensing element characteristics. 2 SPI/I C serial interface (16-bit data output) The LSM330DLC has dynamically user- Programmable interrupt generator for free-fall selectable full scale acceleration range of and motion detection 2 g/4 g/8 g/16 g and angular rate of ECOPACK RoHS and Green compliant 250/500/2000 deg/sec. The accelerometer and gyroscope sensors can Application be either activated or separately put in Low power/Power-down mode for applications GPS navigation systems optimized for power saving. Impact recognition and logging The LSM330DLC is available in a plastic land grid Gaming and virtual reality input devices array (LGA) package. Motion activated functions Table 1.
