Clock chip for microcontroller compatible with Clark and Sepahan forklift panels

The PCF8563 is a CMOS1 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.
