+STM32 32-bit Arm Cortex MCUs has a unique 96-bit serial number which is a concatenation of three 32-bit words, the address is different depending on the microcontroller.

+The [Arduino Core STM32](https://github.com/stm32duino/Arduino_Core_STM32) has the variable UID_BASE whos contain the first 32-bit word of the serial number.
