Description
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. It can generate various interrupt clock pulses lasting for long periods. With low current consumption and an oscillator halt sensing function, it is suitable for equipment requiring small size and low power consumption.
There is also a model called RS5C313 that reverses the logic of serial clock for series goods.
Specifications and 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)
Application Scenarios
The RS5C314 is ideal for applications that require a compact-sized real-time clock with low power consumption. It can be used in various electronic devices such as smartwatches, IoT devices, and small embedded systems.
