  • PCF8563P - Real Time Clock/ Calendar, I2C Interface, DIP8, NXP Semiconductor           


    The PCF8563 is a CMOS 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.


    • 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 μA 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


    • Mobile telephones
    • Portable instruments
    • Electronic metering
    • Battery powered products
