Detail Modul RTC PCF8563 I2C Protocol CMOS Real Time Clock Board

Deskripsi Modul RTC PCF8563 I2C Protocol CMOS Real Time Clock Board
The PCF8563 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

- 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

Aplications
- Mobile telephones
- Portable instruments
- Electronic metering
- Battery powered products
