This device is housed in a SOIC-8 package and operates across a -40\u00b0C ~ +85\u00b0C. It supports a supply voltage range of 2.0V ~ 5.5V. The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The real-time clock uses a 32.768kHz crystal oscillator as the time base, dividing the frequency to produce seconds, minutes, hours, and calendar information. The I2C interface allows the host MCU to read\/write time and date registers. The trickle charger maintains the backup battery when main power is available.","pin_description":"
