Are these real STM32 parts, or clones?

I cannot determine if these are the real SMT32s or not. (Type STM32F103C8T6). The Chinese are excellent at disguising components. However, I have connected all the necessary wiring and loaded my software with my loader and everything works, as it should. I have had no problem with this device. Keep in mind; this is a 3.3v device, even though some connections are 5.0 volt tolerant. Powering with voltages higher than 3.3 ~ 3.5 volts will certainly damage the device. There is an on board 5.0 to 3.3-volt regulator, which has limited current capability. So, power can be applied to the 5.0-v pin without damage. It might be best to order a Nucleo or Discovery board from ST Micro. I hope this helps.
