ST Part Number Identification

[MPera]

After a lot of searching i couldn't find this ST part number. Can anyone identify this part? 

 Is there a way to methodically find pert numbers from ST? 

Thanks in advace.

X2N looks like a marking code to me. Did you try looking for it here? https://www.st.com/content/st_com/en/st25-marking-information.html

Yep, I looked in there with no luck, I'll keep digging. Thanks anyway!!
