NRF9160 VDD_GPIO, Current consumption common conditions

[Andy kang]

I know there is Current consumption common conditions in the datasheet. (table19. nRF9160_PS_v1.2.pdf)

There is VDD level but It's not described the VDD_GPIO level.  

1. I want to know VDD_GPIO level.  please let me know. 

2. Is there a difference total current consumption on 1.8V and 3.3V  VDD_GPIO?

   If so,I want to know how much difference is there modem current comsumption by VDD_GPIO.

Thanks

Hi,

 

1. I want to know VDD_GPIO level.  please let me know. 

You choose the VDD_GPIO level by providing a reference. Please see the PS for the limits: https://infocenter.nordicsemi.com/topic/ps_nrf9160/recommended_op_conditions.html?cp=2_0_0_10

 

2. Is there a difference total current consumption on 1.8V and 3.3V  VDD_GPIO?

 This net will supply your GPIOs. The current consumption will therefore rely on what you use your GPIOs for (LEDs, buttons, pull-resistors, connection to external ICs, etc).

 

Kind regards,

Håkon

Thank you for your answer. 

I already know the range of VDD_GPIO 

I want to know the VDD_GPIO level in Table 1.  Check please.

Hi,

 

Not sure if this is the parameter you're looking for, please let me know if it isn't. The leakage through VDD_GPIO and ENABLE pin is described here:

https://infocenter.nordicsemi.com/topic/ps_nrf9160/_tmp/alta.nRF9160/autodita/CURRENT/parameters.id_system_disabled.html?cp=2_0_0_4_1_0_0

 

As previously mentioned, the total current consumption of VDD_GPIO depends on how you use the GPIOs.

 

Kind regards,

Håkon
