The PCF85063A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via the two-line bidirectional I2C bus. The maximum data rate is 400 kbit/s. The registered address is incremented automatically after each written or read
data byte.
