DS1307 (Real Time Clock IC) Schmitt Trigger and power management moduleIntroduction: The DS1307 serial real time clock (RTC) is a low power, full binary coded decimal (BCD) clock calendar plus 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
