RS5C372A/B I2C bus SERIAL INTERFACE REAL-TIME CLOCK IC OUTLINE NO.EA-044-160219 The RS5C372A is a CMOS type real-time clock which is connected to the CPU via 2-wires and capable of serial transmission of clock and calendar data to the CPU. The RS5C372A can generate various periodic interrupt clock pulses lasting for long period (one month), and alarm interrupt can be made by days of the week, hours, and minutes by two incorporated systems. Since an oscillation circuit is driven at a constant voltage, it undergoes fluctuations of few voltage and consequently offers low current consumption (Typ. 0.5A at 3V). It also provides an oscillator halt sensing function applicable for data validation at power-on and other occasions and 32-kHz clock output for an external micro computer. (Nch.
