DS1307 is a low power, and has 56 bytes of non-volatile RAM entire BCD clock calendar clock chip, address and data through the two wire two-way serial bus transmission, the chip can provide seconds, hours, and other information, day can automatically adjust in every month, and has leap year compensation function. The AM/PM symbol decides clock work in 24 hour or 12 hour mode, chip has a built-in power sensing circuit, which has a power off detecting and battery switching function

The characteristics of DS1307:

It is counting the second, hour, minute, every day, every month and every week, and having a leap year compensation function. Remember the year line 2100.

56 bytes of non-volatile RAM
Two wire serial interface
Programmable square wave output
Automatic power off detecting and switching circuit
In a battery backup mode, the power consumption is less than 500nA
