PCF8564A  
Real time clock and calendar  
Rev. 3 — 26 August 2013  
Product data sheet  
1. General description  
The PCF8564A is a CMOS1 real-time clock 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 the two-line bidirectional  
I2C-bus. Maximum bus speed is 400 kbit/s. The built-in word address register 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  
Wide clock operating voltage: 1.0 V to 5.5 V  
Low back-up current typical 250 nA at 3.0 V and 25 C  
400 kHz two-wire I2C interface (1.8 V to 5.5 V)  
Low-voltage detector  
Alarm and timer functions  
Two integrated oscillator capacitors  
Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz, and  
1 Hz)  
Internal Power-On Reset (POR)  
I2C slave address: read A3h, write A2h  
3. Applications  
Timing devices  
Time of the day tracking  
Process timing  
Alarm  
Portable instruments  
Electronic metering  
Battery powered products
