Description
The DS1338 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Addresses and data are transferred serially through an I2C interface. The clock/calendar provides seconds, minutes, hours, days, dates, months, and years of information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap years. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. The DS1338 has a built-in power sense circuit that detects power failures and automatically switches to the backup supply, maintaining time and date operation
