Tiny Real-Time Clock/Calendar with Alarm Function and I²C-Bus

PCF85063A Active

The 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. Maximum data rate is 400 kbit/s. The register address is incremented automatically after each written or read data byte.
