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.

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 μA at V_DD = 3.0 V and T_amb = 25 °C
• 400 kHz two-wire I²C-bus interface (at V_DD = 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

Applications

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