Description Low-Current I2C RTC
Datasheet DS1306 DatasheetDS1308 Datasheet (PDF)

DS1308 Low-Current I2C RTC with 56-Byte NV RAM General Description The DS1308 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV RAM. Address and data are transferred serially through an I2C interface. 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 operate.
