The DS1307 Real Time Clock is a is a low-power, full binary-coded decimal (BCD) clock and calendar including 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12- hour format with AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply (usually a small coin-cell battery). Timekeeping operation continues while the part operates from the backup supply.

The DS1307 consumes only 500nA from the backup battery for timekeeping - this means even a simple coin-cell battery will last for years.

If you require a pre-built operating circuit please see our other product: DS1307 based Tiny RTC.
