Hi,
I would like to know about the STM32F091's RTC accuracy and frequency error information.
- Is the RTC accuracy or frequency error factor affected only by crystal?
- Is the RTC accuracy or frequency error factor affected by MCU itself?
- Is it any ST document with the related information?
Thanks,
Elvis

the mcu can calibrate the RTC thus modifying the freq error?, not sure is this is what youre asking
