What current is right using Hibernation Mode (RTC)?

Postby senfio » Mon Jun 10, 2019 11:03 pm

Hi Guys, I need help. I'm in doubt.

I want to use the RTC timer and 3 pins of GPIO. When I read the datasheet I see that is possibile in Hibernation Mode. 5uA is great for me!

However, reading the ESP-IDF Programming Guide I found another information, that the RTC IOs are only able with ULP co-processor. Then, my current consuption is not 5uA any more :cry: ! Just because the co-processor is turn on.

Someone could explain me in what document I should believe? Or, if I'm wrong.
Tks.

About ext1
This wakeup source is implemented by the RTC controller. As such, RTC peripherals and RTC memories can be powered down in this mode. However, if RTC peripherals are powered down, internal pullup and pulldown resistors will be disabled.
So ext1+timer = hibernate
