DESCRIPTION
The DS1302 Trickle Charge Timekeeping Chip contains a real time clock/calendar and 31 bytes of static
RAM. It communicates with a microprocessor via a simple serial interface. The real time 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 an AM/PM indicator.
