Regarding the logic voltage of the Jetson Orin Nano module when the power supply is 20V

Please tell me about the logic voltage of the Jetson Orin Nano module.
On page 46 of “Jetson-Orin-Nano-Series-Modules-Data-Sheet_DS-11105-001_v1.2.pdf”, there is “Table 5-3: CMOS Pin Type DC Characteristics”.
If 20V is input to the VDD_IN of the Jetson module,
will the logic voltage of all signals be VIL = 5V or less, VIH = 15V or more?
Thank you in advance.

Hi, Please refer to Table 4-1: GPIO Pin Descriptions for the CMOS logic levels of the GPIOs on the Jetson Orin Nano module.

Thanks

Thank you for your reply.
If that’s the case, then on the other hand, on a Jetson Orin Nano module with a 20V power supply,
are there any signals where the logic voltage is VIL = 5V or less and VIH = 15V or more?
Thank you in advance.

Unfortunately not. You will need to add additional circuitry in your carrier board to support VIH of 15V or more. 20V is VDD_IN is input power supply to the module. It does not mean that 20V input/output logic levels are supported. Thanks

If so, am I correct in understanding that whether the VDD_IN of the Jetson Orin Nano module is 5V or 20V, the voltage of the input/output logic levels of the control and GPIO signals will not change?
Thank you in advance.

Correct. 5V or 20V is input voltage and then onboard voltage regulators regulate it down to the voltages needed by the module. GPIO logic levels remain same irrespective of the VDD_IN supply input within the specified operating range for the module.

I understand. Thank you very much.
