PCF8563
Real-time clock/calendar
16 April 1999
Product specification
1.
General 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.
