LSM330DL Linear sensor module 3D accelerometer sensor and 3D gyroscope sensor Preliminary data Features Analog supply voltage 2.4 V to 3.6 V Digital supply voltage I/Os, 1.8V Low-power mode Power-down mode LLGA 28L 7.5 x 4.4 x 1.1 mm 3 independent acceleration channels and 3 STs family of modules leverages a robust and angular rate channels mature manufacturing process already used for 2g/4g/8g/16g dynamic, selectable full- the production of micromachined accelerometers. scale acceleration range The various sensing elements are manufactured 250/500/2000 dps dynamic, selectable full- using specialized micromachining processes, scale angular rate while the IC interfaces are based on CMOS 2 SPI/I C serial interface (16-bit data output) technology that allows designing a dedicated Programmable interrupt generator for free-fall circuit which is trimmed to better match the and motion detection sensing element characteristics. ECOPACK , RoHS, and Green compliant The LSM330DL has a dynamic, user-selectable full-scale acceleration range of 2g/4g/8g/16g and an angular rate of 250/500/2000 deg/sec. Applications The accelerometer and gyroscope sensors can GPS navigation systems be either activated or put in low-power / power- Impact recognition and logging down mode separately for power-saving optimized applications. The LSM330DL is Gaming and virtual reality input devices available in a plastic land grid array (LGA) Motion-activated functions package. Intelligent power saving for handheld devices Several years ago ST successfully pioneered the Vibration monitoring and compensation use of this package for accelerometers. Today, ST Free-fall detection has the broadest manufacturing capability in the world and unrivalled expertise for the production 6D-orientation detection of sensors in a plastic LGA package. Description The LSM330DL is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope. Table 1.
