1 / 32 page  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 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 32.768 kHz quartz crystal I Century flag I Clock operating voltage: 1.8 V to 5.5 V I Low backup current; typical 0.25 µA at VDD = 3.0 V and Tamb =25 °C I 400 kHz two-wire I2C-bus interface (at VDD = 1.8 V to 5.5 V) I Programmable clock output for peripheral devices (32.768 kHz, 1024 Hz, 32 Hz and 1 Hz) I Alarm and timer functions I Integrated oscillator capacitor I Internal power-on reset I I2C-bus slave address: read A3h and write A2h I Open-drain interrupt pin I ElectroStatic Discharge (ESD) protection exceeds 2000 V Human Body Model (HBM) per JESD22-A114, 200 V Machine Model (MM) per JESD22-A115 and 2000 V Charged Device Model (CDM) per JESD22-C101 I Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA 3. Applications I Mobile telephones I Portable instruments I Electronic metering I Battery powered products PCF8563 Real-time clock/calendar Rev. 06 — 21 February 2008 Product data sheet |
