Electronic Signature for STM32F030K6

[Lloyd Blackbeard]

I think that this serves more as information than a question.

On page 726, section 26 of RM0360, no mention is made of the memory locations and register descriptions for the unique signature. Nevertheless, stm32f0xx_ll_utils.h makes provision for accessing those 96bits.

Hello @Community member​ ,

I raised your feeback internally for correction in the coming release of the reference manual.

Thanks and Kind Regards,

Hello @Community member​ ,

After checking this case, we would inform you that the Unique ID feature is not available in the STM32F030 products and no guarantee it is unique.

It's available for other line products as STM32F0x1/STM32F0x2/STM32F0x8, that's why is mentioned in the stm32f0xx_ll_utils.h

Kind Regards,

Imen

Hi​ @Imen DAHMEN​ ,

Thanks for the information.

Even if it's a "negative" information, could this please still be added to RM0360? The reason is, that it's a somewhat surprising difference against other STM32, so readers of the RM0360 should be notified about it.

Thanks,

Jan

PS. It should also be reflected in the CMSIS-mandated device headers stm32f030xX.h (and for 'F070 too), by removing the UID_BASE symbol.
