URTRA-COMPACT SERIAL ALARM REAL TIME CLOCK ICs
RS5C316A/B
NO. EA-035-0208
OUTLINE
The RS5C316A/B are CMOS type real-time clock ICs which are connected to the CPU via three signal lines and capable of serial transmission of clock and calendar data to the CPU. The RS5C316A/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. 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 an ultra compact and ultra thin 8pin SSOP (0. 65mm pitch), the RS5C316A/B are the optimum choice for equipment requiring small size and low power consumption. The RS5C316A and the RS5C316B reads/writes data at falling and rising edge of serial clock respecti...
