Hello, is there any difference in pheripherals and pinout between STM32F302RB (128kB, LQFP 64) and STM32F302RC (256kB, LQFP 64)

Most likely no, but you should check yourself in the Datasheet.

​ Hello @lazzo.1​ ,

As said by Jan, the datasheet is your reference to compare the peripherals and pinout.  

For the difference between the peripherals, you can also use the ST-MCU-FINDER Tool that provides a part number shortlist based on the user selection of peripherals and MCU characteristics. So, you can compare the characteristics of both MCU.

If the MCUID of the parts is the same, they are the same die.

[waclawek.jan]

They still could be bonded out differently, though...

But for the same package and the same family that is very unlikely...
