We are currently using an F4 (STM32F407IGH6) and an F3 (STM32F303VC) in our product. We want to pull the temperature sensors to get an idea of chip temp. Looking at the datasheets, the F3 data sheet explicitly states that factory calibraiton is done...

We are using an STMF4 and STMF3 in our product and are trying to see if we need to switch to the industrial variant for the extended temperature range.? Is the internal temperature sensor measuring the Die temperature, and if so is that essentially ...
