PCF8564A  
Real time clock and calendar  
Rev. 1 — 8 October 2009  
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 a 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  
I Provides year, month, day, weekday, hours, minutes, and seconds based on a  
32.768 kHz quartz crystal  
I Century flag  
I Wide clock operating voltage: 1.0 V to 5.5 V  
I Low back-up current typical 250 nA at 3.0 V and 25 °C  
I 400 kHz two-wire I2C interface (1.8 V to 5.5 V)  
I Low-voltage detector  
I Alarm and timer functions  
I Two integrated oscillator capacitors  
I Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz and  
1 Hz)  
I Internal Power-On Reset (POR)  
I I2C slave address: read A3h, write A2h  
3. Applications  
I Mobile telephones  
I Portable instruments  
I Electronic metering  
I Battery powered products
