General Description

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 clock 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). In addition, the

HYM8563 contains a programmable clock output, a

timer, an alarm, a voltage-low detector. All address

and data are transferred serially via I2C bus and The

HYM8563 operates as a slave device on the serial

bus. The built-in word address register is

incremented automatically after each written or read

data byte. The HYM8563 is designed to operate on

very low power consumption.
