Are the STM32F301x4 and STM32F302x4 devices discontinued?

Hi everyone,This is a fairly straight forward question. The STM32F301x4 and STM32F302x4 are listed on DigiKey as a non-stock item but are still present on the website when searched. I was unable to find any reference manual for these parts as well. A...

Powering through USB vs powering through VDD vs 5V Pin - STM32 F4 Discovery board

Hi,I am just going through manuals to understand power circuitry on STM32F4 Discovery board for using ADC for voltage sensing.Kindly help in understand difference between internal voltages (VDDA,VSSA,VDD, VREF+ etc) and other impact on power circuitr...

measurement range on stm32

thanks for answering my previous question so according to this i supplied voltages from 0v to 5v and i got following step sizes(if i am correct) what i observed is it stops measuring after 2.5v so does it mean its measuring range is from 0-2.5v / can...
