It provides accurate time and date information with battery backup for embedded systems requiring persistent timekeeping.","working_principle":"The RTC uses a crystal oscillator (external 32.768kHz for DS1307, internal TCXO for DS3231) as the time base. A counter chain divides the oscillator frequency to generate seconds, minutes, hours, day, date, month, and year. The DS3231 integrates a temperature-compensated crystal oscillator (TCXO) achieving plus or minus 2ppm accuracy. Battery backup (VBAT pin) maintains timekeeping when main power is removed.","pin_description":"
