Overview
The RTC-65 series is a real-time clock that was developed as a peripheral IC for PC/AT*-compatible computers,
workstation or other computer systems.
The RTC-65 series has a built-in 32.768kHz crystal. Other functions include a calendar (year, month, day and day of the
week), clock (hours, minutes, seconds), selection of 12-hour or 24-hour timekeeping, automatic leap year adjustment,
and programmable square wave output.
Because this product is a CMOS device, it consumes little current. In addition, a special battery holder provides a backup
power supply, making the RTC-6581/RTC-6591 ideal for backing up CPU data.
