General description

The PCA85063A 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. Maximum data rate is

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

data byte.

For a selection of NXP Real-Time Clocks, see Table 45 on page 50
