Real-time Clock/Calendar PCF8563

DESCRIPTION

The PCF8563 is a CMOS real-time clock/calendar

optimized for low power consumption. A

programmable clock output, interrupt output and

voltage-low detector are also provided. All address

and data are transferred serially via a two-line

bidirectional I 2 C-bus. Maximum bus speed is 400

kbits/s. The built-in word address register is

incremented automatically after each written or read

data byte.
