Introduction
The BU9873 is a CMOS real-time clock, which has a built-in interrupt generation function. This product is connected to the CPU via I²C interface, and configured to perform serial transmission of time and calendar data to the CPU. A high-precision oscillation adjustment circuit is also integrated, which is capable of adjusting time counts with digital method, and correcting deviations in the oscillation frequency of the crystal oscillator.
Features
- Connected to the CPU via I²C Interface
- Time (Hour · Minute · Second, Selectable 12-Hour and 24-Hour Mode Setting)
- Calendar (Year･Month · Day･Week)
- Periodic Interrupt Function (Output from INTRB, Ranging from 1 Second to 1 Month)
- Alarm Interrupt Function (Day-of-Week ･Hour · Minute in Setting Format, Output from INTRB)
- Oscillation Halt Sensing Function
- 32.768 kHz Clock Output (Output from 32KOUT with Control Register)
- ±30 Second Adjustment Function
- Automatic Leap Year Recognition up to the Year 2099
- Built-in Oscillation Stabilizing Capacitors (C_G, C_D)
- High-Precision Oscillation Adjustment Circuit
