The PCF85063BTL/1,118 is a CMOS Real-time Clock (RTC) and Calendar optimized for low power consumption. It provides year, month, day, weekday, hours, minutes and seconds based on a 32.768kHz quartz crystal. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 7Mbps. The register address is incremented automatically after each written or read data byte.
