HW-111A DS1307 I2C Real Time Clock Chip (RTC) 24C32 32K I2C EEPROM memory Use LIR2032 rechargeable lithium battery with charging circuit Solve the problem that DS1307 cannot read or write with backup battery. After fully charged, it can provide DS1307 timekeeping for 1 year. Small design, 27mm*28mm*8.4mm Lead out the clock pin of DS1307 to provide the clock signal for the microcontroller. Other I2C devices can be cascaded. DS1307 is a low-power, full BCD code clock calendar real-time clock chip with 56 bytes of non-volatile RAM. Address and data are transmitted through a two-wire bidirectional serial bus. The chip can provide information such as seconds, minutes, and hours. , The number of days in each month can be adjusted automatically. And there is a leap year compensation function. The AM/PM flag determines the clock to work in 24-hour or 12-hour mode. The chip has a built-in power sensing circuit with power-down detection and battery switching functions. Features of DS1307: It can count seconds, hours, minutes, days of the month, month, and days of the week, and has a leap year compensation function. 2100 is online for the year. 56 bytes of non-volatile RAM Two-wire serial interface Programmable square wave output Automatic power failure detection and switching circuit In battery backup mode, power consumption is less than 500nA HW-111B DS1307 I2C Real Time Clock Chip (RTC) 24C32 32K I2C EEPROM memory Using CR2032 battery Solve the problem that DS1307 cannot read or write with backup battery.
