# Confidential Data Section for W7500P

## Question

Asked by mutlu on 2018-01-26 in MCU & Boards.

Hi,

W7500P datasheet has a section called information block (Lock info).
Can we use it to store the key?

I’m also curious about this region. I looked for it, but couldn’t find any leadings.
Maybe the Data0 and Data1 might be usefull for you, if they aren’t already on use.
