Looking at AN4733 figure 1, it looks like the Tamper inputs are in the VBAT power domain but I don’t see a path to clear the key. It doesn’t look like the tamper
pins can erase the key. Are these pins only useful if main power is on?
Hi Alex,
I just got the feedback, the expert told me there is some issue for Figure 1, which is not complete/accurate, but she assured me that the tamper inputs are connected to the key erase logic.
Hope that helps,
Have a great day,
Kan
