Productomschrijving

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.
