DESCRIPTION
The DS1305 Serial Alarm Real Time Clock provides a
full BCD clock calendar which is accessed via a simple
serial 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 less than 31 days, including corrections for
leap year. The clock operates in either the 24–hour or
12–hour format with AM/PM indicator. In addition 96
bytes of nonvolatile RAM are provided for data storage.
