I2C1 Negative Overshoot - STM32U5G9

We are using STM32U5G9's I2C with a diff-I2C to single ended I2C converter IC PCA9616. PCA9616 is used to program the STM32 MCU over I2C1 by converting diff-I2C to single ended I2C.However, while probing the I2C1 of the STM32U5G9, we are seeing negat...

Continuous Reboot Issue with STM32G070CBT6

Hello,We are currently using the STM32G070CBT6 microcontroller in one of our data logger devices, which operates on a three-phase power supply and is used in a transformer application. In our design, the microcontroller triggers a relay, and the rela...
