UART output voltage information [STM32F413]

Hi !

 

I'm currently using STM32F413 uC.

 

I can not find on the datasheet (and the reference manual) the output voltages of UART pins (or even GPIO).

The voltage of course depends on the supply voltage. I'm currently powering my microcontroller with a voltage of 3.3V but my output signals on the UART pin are 1.8V...
Where can I find this information?

 

Thanks in advance !
