Pin connections

The LSM6DSTX offers flexibility to connect the pins in order to have four different mode connections and

functionalities. In detail:

•

Mode 1: I²C / MIPI I3CSM slave interface or SPI (3- and 4-wire) serial interface is available

•

Mode 2: I²C / MIPI I3CSM slave interface or SPI (3- and 4-wire) serial interface and I²C interface master for

external sensor connections are available

•

Mode 3: I²C / MIPI I3CSM slave interface or SPI (3- and 4-wire) serial interface is available for the application

processor interface while an auxiliary SPI (3- and 4-wire) serial interface for external sensor connections is

available for the gyroscope ONLY.

•

Mode 4: I²C / MIPI I3CSM slave interface or SPI (3- and 4-wire) serial interface is available for the

application processor interface while an auxiliary SPI (3- and 4-wire) serial interface for external sensor

connections is available for the accelerometer and gyroscope.
