PCF8563
Real time clock/calendar
Rev. 03 -- 14 April 2003 Product data
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 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
s Provides year, month, day, weekday, hours, minutes and seconds based on 32.768 kHz quartz crystal s Centur y flag s Clock operating voltage: 1.8 to 5.5 V s Low backup current; typical 0.25 µA at VDD = 3.0 V and Tamb = 25 °C s 400 kHz two-wire I2C-bus interface (at VDD = 1.8 to 5.5 V) s Programmable clock output for peripheral devices (32.768 kHz, 1024 Hz, 32 Hz and 1 Hz) s Alarm and timer functions s Integrated oscillator capacitor s Internal power-on reset s I2C-bus slave address: read A3H and write A2H s Open-drain interrupt pin.
3. Applications
s s s s Mobile telephones Por table instruments Fax machines Batter y powered products.
