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. Maximu m bus speed is 400
kbits/s. The built-in word address register is
incremented automatically after each written or read
data byte.
