PCF8563 IC - (SMD SOP-8 Package) - Real Time Clock (RTC) and Calendar IC

The PCF8563 is a CMOSI Real-Time Clock (RTC) and calendar optimized for low powrer consumption. A programmable clock output, interrupt output, and voltage-low detector are also provided. All addresses and data are transferred serially via a tv.'&line bidirectional 12C-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 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) • I 2C-bus slave address: read A3h and write A2h • Open-drain interrupt pin Applications:- ● Mobile telephones ● Portable instruments ● Electronic metering ● Battery powered products Related Document:- PCF8563 IC SMD Data Sheet
