RTC

Hello,

What is the meaning of RTC for the STM32L431 when supplied with Vbat?

Does it mean that the RTC time continues to increase when Vbat is present and VDD=0V?

Table 5 of the datasheet permits to hope it ....

Best regards

Mich

Yes, read the section "5.1.4 Battery backup domain" in the reference manual (RM0394) - https://www.st.com/resource/en/reference_manual/dm00151940.pdf

OT: please use a more descriptive topic title in the future. In this case it could have been "RTC and the VBAT pin"
