Real-Time Clock (RTC) and calendar

The PCF8523 is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. Data is transferred serially via the I2C-bus with a maximum data rate of 1000 kbit/s. Alarm and timer functions are available with the possibility to generate a wake-up signal on an interrupt pin. An offset Provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal\nResolution: seconds to years\nClock operating voltage: 1.0 V to 5.5 V\nLow backup current: typical 150 nA at VDD = 3.0 V and Tamb = 25 °C\n2 line bidirectional 1 MHz Fast-mode Plus (Fm+) I2C interfa;
