STR712FR2T6 /ST712FR2T6 Marking & Date Code

[JoelST]

We have the parts ST712FR2T6  and we have tested them according to datasheet. Passed all visual, electrical, solderability and X-ray. What we’re concermed about is the date code and Bulk ID.
1. Can you confirm that ST used this marking ST712FR2T6?
2. Confirm that the Bulk ID is the ID of ST Micro?
3. Confirm if the DC is 2023 or 2013? We’re aware the EOL of parts was 2021

Hello,

Missing the letter “R” in the part number is weird. ST7 is a 8 bit MCU while STR7 is a 32-bit ARM based microcontroller. 

The top marking shows “ARM”, while the part number is missing “R”… I have a doubt they are fake!

Hi your colleague, Peter gave this response before:
Can you verify, because you’re now say two completely different things? Thanks in advance
