LSM330DLC electrical connection

5.1

External capacitors

The device core is supplied through the Vdd line. Power supply decoupling capacitors (C2,

C3=100 nF ceramic, C4=10 µF Al) should be placed as near as possible to the supply pin of

the device (common design practice).

All voltage and ground supplies must be present at the same time to achieve proper

behavior of the IC (refer to Figure 13).

The functionality of the device and the measured acceleration/angular rate data is

selectable and accessible through the SPI/I2C interface.

The functions, the threshold and the timing of the two interrupt pins for each sensor can be

completely programmed by the user through the SPI/I2C interface.

Digital signal from/to signal controller.Signals levels are defined by proper selection of Vdd
