How to identify a genuine STM32 MCU and where to purchase genuine STM32 MCU ?

[Ricky Gai]

I am new to STM32, recently came across the compatibility of none genuine STM32 MCU issues.

For example, I found the STM32F103C8T6 chip link at HERE, which one is genuine STM32 MCU in this case ?

Secondly, where can I find a trusted vendors that supply genuine STM32 MCUs ( discrete STM32 MCU like STM32F103C8T6, none development board in this case ), any recommendation ?

Please advise.

Not random stock rooms in China, Hong-Kong..

While you can find good parts, it can be hit and miss, and second buys might come from different reels, etc.

You pay your money, you take your chances..

Legitimate, first-hand sources are places like Mouser, DigiKey, AVNET, Verical, Farnell

E.g. read out the RomTABLE PIDR. Genuine parts tell Designer 0x20, partno 410.
