Firmware Protection (F1 Series)

Hello dear! I'm developing a new product. I would like use the STM32 F1 series, but I was surprised with this: https://blog.zapb.de/stm32f1-exceptional-failure/The F1 Series don't have RDP Level 2 protection, in this case, what's the most security wa...

STM32U5 ADC specifications?

I am planning to use ADC with 16 bits achieved using oversampling in STM32U5.But on Datasheet there is no data wrt to ADC oversampling.Can somebody help me with data regarding ENOB, EL,ED when ADC is oversampled. Datasheet : DS13737Datasheet - STM32U...

Resolved! If I want to control a relay via the TX of a UART do I just connect the appropriate STM32 pin to the relay? Or is there anything else I need to do (besides programming)?

I'm looking to use a ITS4200S-ME-P relay to switch a high voltage signal and would like to control that via a UART. Per the datasheet this relay, "can be switched on and off with standard logic ground related logic signal at pin IN."
