Hi

Can anyone please tell me if there is a unique id or serial number for ARM stm32f103rbt6 microcontroller and how to find it. I need this for tracking. Any help will be really appreciated.

I do not use STM32's, but doing a google search found that they do. It's a 96bit value called the Device Electronic Signature.

Thanks for your information . I used that software but it doesn't work with stm32f103rbt6. Had to download Mathlab and another 2 software just to make it Run . I searched in google for solution but didn't find any suitable for this particular microcontroller. If any1 knows any other way please let me know. I am using keil u vision . thanks

Can't you just write an ID into non-volatile on-chip memory?

I have no idea what you are talking about with software. The unique ID is just located at a ROM address. Just read the address. It's 3 32bit integers long. Here's some code.
