ST marking name

[hermann_core]

Hello. I bought a STM32G474MET6 chip on Alibaba and the supplier claims that the chip is original but I have some doubts. Here are the attached images he sent to me. Can you please check that and confirm if it’s genuine please ?

Looks sketchy to me. Several inconsistencies. Very early production, newer parts don't look marked quite the same

My guess would be early engineering samples of the Cut 2.2 (Y) silicon around Nov/Dec 2019
