I want to connect 3 LEDs(each 20mA) to 3 GPIOs directly for low cost (not use external transistors).
Datasheet says 200mA of maximum total chip current but I can't find specification of each gpio.
Is there any specification of current on each gpio or any solution?

Hi,
I also could not find operation rating for GPIO current,
but in Table.2 Absolute Maximum Ratings,
it says +/- 25mA, so probably 20mA for each would be acceptable.
