nRF52840: Max current consumption on the supply pins

[Rulu]

Hello

What is the specified max current on the supply pins for nRF52840?

The GPIO pins are specified to source max 14mA in 'high drive' mode:

How many of these pins can be used to source 14 mA simultaneously and still have margin on the total 'current bugdet' for the device?

Hi,

 

Unfortunately, we do not have this specified in the PS.

However, there are a couple of threads on this matter, where nordic employees have answered (pads on nRF52832 is similar to nRF52840), where 50 mA has been mentioned:

I have reported your request internally.

 

Kind regards,
