Product data sheet  
1. General description  
The PCF8563 is a CMOS1 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  
I2C-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  
Century flag  
Clock operating voltage: 1.0 V to 5.5 V at room temperature  
Low backup current; typical 0.25 A at VDD = 3.0 V and Tamb = 25 C  
400 kHz two-wire I2C-bus interface (at VDD = 1.8 V to 5.5 V)  
Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz, and  
1 Hz)  
Alarm and timer functions  
Integrated oscillator capacitor  
Internal Power-On Reset (POR)  
I2C-bus slave address: read A3h and write A2h  
Open-drain interrupt pin  
3. Applications  
Mobile telephones  
Portable instruments  
Electronic metering  
Battery powered products
