OUTLINE
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 (0.65mm pitch), the RS5C314 is the optimum choice for equipment requiring small size and low power consumption.
There is RS5C313 reversing the logic of serial clock for series goods.FEATURES
• Time Keeping Supply Voltage: 1.6 to 6.0 V
• Operating Supply Voltage: 2.7 to 6.0 V
• Low Current Consumption: TYP. 0.7µA (MAX. of 1.5µA) at 3V
• Connection to the CPU via only three pins: CE, SCLK, and SIO (for addressing and data read and write operations)
• A clock counter (counting hours, minutes, and seconds) and a calendar counter (counting leap years, years, months, days, and days of the week) in binary-coded decimal (BCD) code
• Generation of interrupt pulses to the CPU with cycles ranging from 1 month to 1/1024 Hz, interrupt flags, and interrupt halt
• Software-based alarming through clock-interlocked interrupt operation
• Oscillator halt sensing to judge internal data validity
• Second digit adjustment by ±30 seconds
• 12-hour or 24-hour time display selectable
• Automatic leap year recognition up to the year 2099
• CMOS logic
• Package: 8pin SSOP (0.65mm pitch) -
