Hi teams

The voltage domain of RESET_N is VDDIO, but when VDDIO is turned off in TC-10 mode, RESET_N will be left floating. Should any additional handling be done in this case?

Hi Kung,

Is the design similar to the below block diagram?

No additional handling should be needed in this case.

Best regards,

Melissa

So can I assume that RESET-N is inactive in TC-10 mode? If it is active but floating, I am concerned about noise interference.

Hi Kung,

Toggling the RESET_N in TC-10 sleep mode will have no effect on the device. What do you mean by noise interference?

Best regards,

Melissa

If it's not affected, then it's fine.
