password protection for pointer area

[ToIk_1341346]

Target SNOR series: S25FL064L , S25FL128L

I would like to protect the area of 256KB with a password lock.
Therefore, the capacity will be insufficient only in security area 2 and area 3.

It seems that the pointer area can also be password locked.
When I use the pointer area, can the size of 256KB be password-locked?

Hello,

I am not sure if I understand your question accurately. My understanding is that you want to use password protection to protect 256KB data. But the security region (1024 bytes) is not enough. You want to know if memory array region using Pointer Region Protection (PRP) can be password protected.

If you want to protect the region from erase/program, the answer is yes. The pointer region can be password-locked. Only Security Region 3 can be read protected.

Thank you
