Maximum GPIO Current


Recommended Posts

Hey everyone; been a while!

 

I'm looking at a project that brought up a question I can't find an answer to. I've tried searching the forum here with no success, but perhaps someone knows the answer:

 

In the device datasheets, it specifies the maximum current draw/sink at 48 mA for the GPIO. Is that per port, or per device? (ie. can I draw 40 mA from P1 AND 40 mA from P2?)

In my experience, I have not been able to supply nor sink more than 10mA from any one IO pin (ie:P1.1 )

 

So, I would guess that 48mA would be a number that adds up all current from all pins on one port (ie: P1.[0..7])
