Product Summary

The HYM8563 is a CMOS real time clock/calendar, which provides seconds, minutes, hours, day, date, month, and year information. The number of days in each month and leap years are automatically adjusted. The HYM8563 can operate in two modes: one is the 12-hour mode with an AM/PM indicator, the other is the 24-hour mode. The clock/calendar is full binary-coded decimal (BCD). The applications of the HYM8563 include Cash Register, Security Access Controller, Door Controller, Time Recorder, Mobile Telephones, Public Phone Bill Meter, Smart Card Payphone, MP3/MP4 Player and IC Water-Flow Meter, IC Gas Meter.
