Change GPIO pin voltage from 3v to 5v for KE06Z.

Hello,

I need the GPIO output to be 5v but it's currently outputting 3v. I'm trying to use the pin map in MCUXpresso to pullup the pin but it doesn't seem to work. Is this possible? Thank you.

Best,

Tyler Wong

Hi Tyler Wong,

Would you please check if the KE06Z is powered by 5V?
If so the GPIO should be able to output 5V by default.
Otherwise only PTA2 and PTA3 can output 5V. These two pins are true open-drain pins when operated as output, so external 5V pullup is available.

Best Regards,

Robin

Hello Robin,

Thank you for the response. It states that the KE06 can be powered by 5V or 3.3V. Does this mean that 5V output is possible? Thank you.
