Product data sheet
1. General description
The PCF8563 is a CMOS
1
Real-Time Clock (RTC) and calendar optimized for low power
consumption. A programmable clock output, interrupt output, and voltage-low detector are
also provided. All addresses and data are transferred serially via a two-line bidirectional
I
2
C-bus. Maximum bus speed is 400 kbit/s. The register address is incremented
automatically after each written or read data byte.
2. Features and benefits
Provides year, month, day, weekday, hours, minutes, and seconds based on a
32.768 kHz quartz crystal
