RS5C316A/B
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 volt-
age, 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 occa-
sions. 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 respectively.
Time keeping voltage 1.6V to 6.0V
Lowest supply current 0.6μA TYP. (1.5μA MAX.) at 3V
Connection to the CPU via only three pins: CE, SCLK/SCLK and SIO for addressing and data read/write
A clock counter (counting hours, minutes, and seconds) and a calendar counter (counting leap years, years,
months, days, and days of the week) in BCD code
Periodic interrupt pulses to the CPU with cycles ranging from one month to 1/1024Hz, with interrupt flags and
interrupt halt
Alarm interrupt (days of the week, hours, minutes)
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)
