How do you expect this forum to help?

You need to take this up with your supplier, if you think it's an unacceptable substitute

[Andrew Neil]

Or are you just asking what's the difference between STM32F205RFT6 and STM32F205RET6 ?

The answer to that is in the datasheet:

[GAzen.1]

Yes i know that, i tell about the marking code device

[GAzen.1]

i have a E on the component but a R on the label

[Andrew Neil]

Again, if you think your supplier has sent you the wrong part, then you need to take that up with them.

Was it a reputable supplier...?

Or, if your not sure about the markings, and want confirmation of what you think you're seeing, then you need to post some good, clear, in-focus pictures of what you have - we can't see it any other way!
