nRF52840-QIAA-R vs nRF52840-QIAA-F-R

[Dominik Eugster]

Hi

We are using the nRF52840-QIAA-R in a lot of PCBA, now I see there is a new revision nRF52840-QIAA-F-R and the old type is not recommended for new design.

What is the difference between the 2 types and are they 100% compatible? Where can I see the difference between the old and the new type?

Thank you

Thank you, but there the change is only pointing on the ESD specifications:

This is the reason for NRND?

Because here it's written that the access port protection is controlled by software and ahrdware, what this means? This has nothing to do with ESD.
