ULTRA-COMPACT HIGH PERFORMANCESERIAL REAL-TIME CLOCK ICs RS5C317A/B
capable of serial transmission of clock and calendar data to the CPU;
The RS5C317A/B can generate various periodic interrupt clock pulses lasting for long period (one month), further
alarm interrupt can be made by days of the week, hours, and minutes. The function of 32kHz clock output and timer
counter for watch-dog-timer are also include. Driving an oscillation circuit at constant voltage, the circuit undergoes
few voltage fluctuations and consequently realizes low current consumption (0.6µA at 3V). It also provides an oscillator
halt sensing function for application to data validity at power-on and other occasions. Integrated into a compact
and thin 14pin SSOP (0.65mm pitch), the RS5C317A/B are the optimum choice for equipment requiring small size
and low power consumption;
The RS5C317A and the RS5C317B reads/writes data at falling and rising edge of serial clock respectively
