CBM13S39A I ²C The various programmable features of the C serial real-time clock RTC provide more flexibility for the system

The CBM13S39 serial real-time clock (RTC) is a lowpower clock/date device with two programmable timeof-day alarms and a programmable square-wave output. Address and data are transferred serially through an I2C bus. The clock/date provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month 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 CBM13S39 has a built-in power sense circuit that detects power failures and automatically switches to the backup supply, maintaining time, date, and alarm operation.
