Pin connections

The LSM6DS3US offers the flexibility to connect the pins in order to have three different

mode connections and functionalities. In detail:



Mode 1: I2C slave interface or SPI (3- and 4-wire) serial interface is available;



Mode 2: I2C slave interface or SPI (3- and 4-wire) serial interface and I2C interface

master for external sensors connections are available;



Mode 3(a): I2C slave interface or SPI (3- and 4-wire) serial interface is available for the

application processor interface while an auxiliary SPI (3-wire) serial interface for

external sensor connections (i.e. camera module) is available.

Figure 2. LSM6DS3US connection modes

In the following table each mode is described for the pin connection and function.

a. In the primary SPI connection, the gyroscope output data is available in registers 22h to 27h with user-selected

FS and ODR. In the auxiliary SPI connection, gyroscope output data is available in registers 22h to 27h

@ 3.3 kHz and FS = 250 dps.
