Product Summary
The DS1302Z is a trickle-charge timekeeping chip. It contains a real-time clock/calendar and 31 bytes of static RAM. The DS1302Z 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 fewer 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.
