Description

The PCF8563T is a CMOS1 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. PCF8563T Features • 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 A 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 PCF8563T Applications • Mobile telephones• Portable instruments• Electronic metering• Battery powered products
