This product is not recommended for new designs, instead, we recommend the PCA85073A.
The PCA85063A 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.
