Hello I am developing a evaluation board for STM32F427. I am connecting an external **RTC** IC (DS3231). Do i need to connect an other external oscillator for processor? Because in STM32F407 discovery board they have connected an external 8MHz crystal other than 32.768KHz which is used for **RTC**.
