How much current can a GPIO port of stm32n6 can source and sink?

[GBA]

I am working with an STM32N6 microcontroller and need clarification about the electrical characteristics of its GPIO pins. How much current a GPIO can source and sink. Is it in micro Amps or mili Amps.

Hello @GBA and welcome to the community,

STM32N6 GPIO pin can source or sink up to ±20 mA.

From the datasheet page 172:

20 mA source or sink. See the datasheet for details.

As the others have said, this is stated in the datasheet.

Note that there is also a limit on the sum total of all GPIOs ...
