What is the starting address of the 96-bit Unique ID on the STM32F030 processors? I cannot find this information anywhere in the reference manual or datasheet. Is this guaranteed to exist on the F0 series?

Chap 27, also would seem to confirm that it's not present/supported in your chosen chip. Would appear to be a purposeful omission.

Hi derensis.thomas,

I confirm that the Unique ID isn't available for STM32F030x4/6/8/C and STM32F070x6/B (the ones covered by RM0360).

Please note that STM32F050 devices were renamed to STM32F031 (RM0091). Tha's why it supports the Unique ID feature.
