NXP's PCF85063ATL is a CMOS 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 register address is incremented automatically after each written or read data byte.
