MIMXRT1061 input impedance with no power supply

I am designing custom board with mimxrt1061dvl6b.

The problem is,

when power supply  for mimxrt1061 is off,

GPIo of RT1061 is in low state. I need high impedance state.

Is there any solution for it?

Hi @Mithy,

As mentioned on this post: https://community.nxp.com/t5/i-MX-RT/Strange-behavior-of-some-pins-with-MCU-in-reset/m-p/950175

"i.MXRT family device pads have no high impedance ability, so even you cause a reset state with the POR_B, the pin will be configured as GPIO by default."

Sorry for the inconvenience this may cause.

BR,
Edwin
