PCF8563
PCF8563; Real-time clock/calendar
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 IC-bus. Maximum bus speed is 400 kbits/s. The built
register is incremented automatically after each written or read data byte.
