How to identify information printed on STM32F407IGT6 chips?

I have two STM32F407IGT6 chips, and I need help understanding the markings printed on their surfaces.

  • Images attached:
    • First chip: "STM32F407IGT6 AA295 VQ 6 TWN AA 342"
    • Second chip: "STM32F407IGT6 VQ249473 AA297 TWN AA 318"

I would like to know:

  1. What each line of the markings represents?
  2. How to verify the authenticity of these chips?
  3. If there are any important differences between these two chips based on the markings?

Any detailed guidance or resources to decode this information would be greatly appreciated. Thank you!

Hello,

The information needed by the user is provided in the datasheet:

We don't provide detailed explanation. And the two chips are genuine.

Many new chips have 2D QR code marking. for more details you can contact your local FAE/Sales.
