Working Principles

The X1228S14I combines a non-volatile memory and a real-time clock in a single integrated circuit. The non-volatile memory allows for data storage even when power is disconnected, ensuring data retention. The real-time clock provides accurate timekeeping and calendar functions. During normal operation, the IC is powered by the main supply voltage. In case of a power loss, the IC automatically switches to battery backup mode, allowing uninterrupted timekeeping and data retention.
