Why does RCC_APB1ENR:TIM2_EN get cleared in Stop Mode when DBGMCU is set?

We noticed that our TIM2 did not count after our STM32L152 went to Stop Mode and woke up again.When we analyzed the problem, we found that our debug probe set DBGMCU to DBG_STANDBY | DBG_STOP | DBG_SLEEP. When we power cycled the µC or set DBGMCU to ...

How many manufacturing heat cycles can DSP device STM32F107VCH6 withstand before it functionality/quality is compromised?

Hi, We are using DSP device STM32F107VCH6 and would like to know how many heat cycles the chip can withstand before its operation is compromised, by heat cycles we mean surface mount reflow cycles and any subsequent removal for rework / component sal...
