    GPIO pins of CY8C5868AXI-LP035

    abhijit.kuvar

       What factor decides how much of current would be drawn out from GPIO pins of CY8C5868AXI-LP035?

         

      I having my microcontroller being run on 3.3 V. So output from GPIO pins would be on 3.3 V logic. Now some of these GPIO pins go as inputs to data acquisition system for which I am using AD7606 (Analog Devices part). So do I connect GPIO pins directly to AD7606 or should I have resistance in between?

         

      NOTE: AD7606 logic input can sink/source 2 uA.
