STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I am using the STM32L151 processor.I noticed that the LSE takes between 140ms and 712ms to get ready RCC_FLAG_LSERDY. I think Is a time of 700ms still a correct time? Fluctuations are normal?code:while ((uint16_t)RCC_GetFlagStatus(RCC_FLAG_LSERDY) ==...
