Hi STMicroelectronic,

I have the MCU pard number STM32F101RCT6 and I would like to know the date code of this IC.

The markking on the IC show 815 but I am not sure it mean from 2008 or 2018. see picture as attached.

Could you please advise on this?

STM32F1 series

The STM32 family was introduced 2007, so I think 2008 it was not that far spread. Maybe other devices on the board can a hint too. And maybe the unique number. Some families have the run number encoded. I wonder why four digit date codes are not used.
