LSM330DL
The LSM330DL is a system-in-package featuring a 3D digital accelerometer and a 3D digital
gyroscope.
The complete device includes specific sensing elements and two IC interfaces able to
measure both the acceleration and angular rate applied to the module and to provide a
signal to the external world through an SPI/I²C serial interface.
The various sensing elements are manufactured using specialized micromachining
processes, while the IC interfaces are based on CMOS technology that allows designing a
dedicated circuit which is trimmed to better match the sensing element characteristics.
The LSM330DL may also be configured to generate an inertial wake-up and free-fall
interrupt signal according to a programmed acceleration event along the enabled axes.
3.1
Factory calibration
The IC interface is factory calibrated for sensitivity and zero level. The trimming values are
stored inside the device in non-volatile memory. Any time the device is turned on, the
trimming parameters are downloaded into the registers to be used during normal operation.
This allows using the device without further calibration.
