Description
The RS5C316B is a CMOS type real-time clock IC that is connected to the CPU via three signal lines and capable of serial transmission of clock and calendar data to the CPU. It can generate various periodic interrupt clock pulses lasting for a long period, and alarm interrupt can be made by days of the week, hours, and minutes. The RS5C316B has low current consumption and provides an oscillator halt sensing function. It is integrated into an ultra compact and ultra thin 8-pin SSOP package, making it suitable for equipment requiring small size and low power consumption.
Specifications and features
- 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: 8-pin SSOP (0.65mm pitch)
