LSM330DTR STMicroelectronics

LSM330D 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 (3x5.5x1.0 mm) 3 independent acceleration channels and 3 angular rate channels The various sensing elements are manufactured 2 g/4 g/8 g/16 g dynamically selectable using specialized micromachining processes, full scale while the IC interfaces are developed using a 250/500/2000 dps dynamically selectable CMOS technology that allows the design of a full scale dedicated circuit which is trimmed to better match 2 the sensing element characteristics. SPI/I C serial interface (16-bit data output) The LSM330D has dynamically user-selectable Programmable interrupt generator for free-fall full scale acceleration range of 2 g/4 g/8 and motion detection g/16 g and angular rate of 250/500/2000 ECOPACK RoHS and Green compliant 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 LSM330D is available in a plastic land grid Gaming and virtual reality input devices array (LGA) package. Motion activated functions Intelligent power saving for handheld devices Table 1.
