ULTRA-COMPACT REAL-TIME CLOCK IC
RS5C314
OUTLINE
EK-082-9908
The RS5C314 is a CMOS type real-time clock which is connected to the CPU via three signal lines and capable of serial transmission of clock and calendar data to the CPU. The RS5C314 can generate various interrupt clock pulses lasting for long periods (one month). Driving an oscillation circuit at constant voltage, the circuit undergoes few voltage fluctuations and consequently realizes low current consumption (TYP. 0.7µA at 3 V). It also provides an oscillator halt sensing function for application to data validity at power-on and other occasions. Integrated into an ultra-compact and ultra-thin 8pin SSOP (0.
