Can I2C pins be in different ports?

Hi,I’m currently implementing I2C in slave mode using the STM32G491 series. Due to pin constraints, we’re considering using SCL and SDA pins from different GPIO ports—for example, SCL from port PA and SDA from port PC. Is it acceptable to assign I2C ...

Resolved! Possible risks of voltage drop in VDD of STM32F3

Hi !I am evaluating the risks associated with STM32F3, where I am speculating a case where the voltage drops in VDD for few microseconds. For an example, let us assume the voltage drops from 3.3V to 3.0V for few microseconds. This occurs every x ms (...

Resolved! STM32H750 rev V or Y

Hello ST experts,I have bought a STM32H750IBT microcontroller. Could you please let me know how I can find whether it is V revision or Y revision device?
