Product introduction:
DS1307 is a low-power, full BCD code clock calendar real-time clock chip, with 56 bytes of non-volatile RAM.

DS1307 I2C real time clock chip, 24C32 32K I2C EEPROM memory, the DS1307 is accessed via the I2C protocol.

Solve the problem DS1307 with backup battery can not read and write, In battery backup mode, Low power consumption.

Address and data are transmitted through a two-wire bidirectional serial bus.

The chip can provide seconds, minutes, hours and other information , The number of days in each month can be adjusted automatically. And there is a leap year compensation function. The AM/PM flag bit determines that the clock works in 24-hour or 12-hour mode.

The chip has a built-in power sensing circuit with power-down detection and battery switching functions.

Lead out the clock pin of DS1307 to provide clock signal for the microcontroller

DS1307 parameter:

It can count seconds, hours, minutes, days of the month, months, and days of the week, and has the function of leap year compensation. Yearbook Online 2100.
