is a CMOS Real-Time Clock (RTC) and calendar optimized for low power
consumption. A programmable clock output, interrupt output, and
voltage-low detector are also provided. All addresses and data are
transferred serially via a two line bidirectional I2C-bus. Maximum bus speed is 400 kbit/s. The register address is incremented automatically after each written or read data byte.
