STM32 MCU Connection Issue with ST-LINK

I am currently working with an STM32 MCU and facing an issue while trying to connect the board to my PC using an ST-LINK debugger. The board powers on normally and there does not appear to be any obvious hardware issue, but STM32CubeProgrammer is una

STM32L053: Unexplained power consumption jump from ~30µA to 6.0mA in STOP/LPSLEEP mode

Hi everyone,I'm working on a battery-powered flow meter application using the STM32L053, and I'm running into a massive, unexpected jump in power consumption.Previously, our device was successfully hitting the 0.0xx mA (around 30µA) range while maint

gpio power consumption

Hello Team, I am using STM32N6,I am using about 50 GPIOs, all for SPI and I2C communications, and the VDD port supplies 200mA, Will the usage of all these pins consume less than 200mA, or do I have to widen the range of VDD? Also, what is the total m
