Frequently Asked Questions
What operating voltage should power the I2C-bus interface?
The I2C-bus requires an operating supply voltage between 2.5 V and 6 V.
How can I program multiple slave devices to the bus?
The address pin A0 is used for programming the hardware address, allowing the connection of two ICs without extra hardware.
What types of time base frequencies are available for the clock function?
It supports a 32.768 kHz or 50 Hz time base depending on the application requirements.
How does the chip signal when an alarm or timer event occurs?
The device outputs to an open-drain interrupt output that switches active LOW when the alarm or timer flag is set.
