D8563 is a low-power CMOS real-time clock/calendar circuit that provides a programmable clock output, an interrupt output, and a power failure detector. All addresses and data are transmitted serially through the IC bus interface. The maximum bus speed is 400Kbits. After each read and write of data, the embedded word address register will automatically generate an increment.
