RICOH RS5C372A/B I 2 C bus SERIAL INTERFACE REAL-TIME CLOCK IC Manual
Update: 30 September, 2023
The RS5C372A is a CMOS-type I2C bus interface real-time clock IC that uses 2 wires to connect to the CPU and is capable of serially transmitting clock and calendar data to the CPU. The RS5C372A can generate various periodic interrupt clock pulses lasting for long periods (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. 0.5μA 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. open drain output) The product also incorporates a time trimming circuit that adjusts the clock with higher precision by adjusting any errors in crystal oscillator frequencies based on signals from the CPU. The crystal oscillator may be selected from 32.768kHz or 32.000kHz types. Integrated into an ultra compact and ultra thin 8 pin SSOP package, the RS5C372A is the optimum choice for equipment requiring small sized and low power consuming products.
