1Chip Overview

HM8563 is a CMOS real-time clock/calendar chip optimized for low power consumption.

The timing counter consists of century, year, month, day, date, hour, minute and second bits.

External MPU can read or set the time as well as timer or alarmer when it is necessary. As

dramatically, which is very suitable in a complicated system.

The chip has the following features:

An external 32.768 kHz crystal is needed to generated time base

Wide operating supply voltage range: 1.0 to 5.5 V

Programmable clock output for peripheral devices: 32.768 kHz, 1024 Hz 32 Hz

and1Hz
