Preliminary Datasheet RTC8563S I2C Real Time Clock/Calendar General Description The RTC8563S 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 RTC8563S 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 RTC8563S 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.
