Figure 34:

Application Example with Using the ALERT Functionality

In Figure 34 the connections of the AS6221 temperature sensor to a microcontroller and the supply

voltage are shown.

The AS6221 is connected to a microcontroller via an I²C bus (SDA and SCL only). Additionally the

Alert output can also be used for temperature monitoring (e.g. using the interrupt mode, refer to IM bit

settings), an example is given in Figure 34 where the Alert output is connected to microcontroller.
