Current Value of all Input/ Output Current for STM32F103RBT6

[stu1]

What will be the total output current sunk by sum of all I/Os and control pins and Total output current sourced by sum of all I/Os supplied by VDDIO2 of STM32F103RBT6?

Dear @stu1 ,

We have no VDDIO2 internal Rail in the STM32F1 series , all VDDx should be connected to the same board Rail . Here is the datasheet for more details

Hope it helps you .

That describes the limits & capabilities of the pins - but the actual currents will depend on the loads connected to the pins.

[Andrew Neil]

That will depend entirely on the external circuitry connected to those those  I/Os and control pins!

A pin driving an LED will sink/source much more current than a pin that's driving a CMOS input.

[stu1]

Correct. So, I required how many LEDs I can connect to this controller for single unit of time. How much amount of current all the GPIOs can handle at a time?

That was answered in the images posted by @STOne-32
