Working Principles

The DS1743WP-120IND+ combines a real-time clock and non-volatile RAM. The real-time clock uses a crystal oscillator to generate a precise 32.768 kHz clock signal. It keeps track of time, date, and day of the week. The non-volatile RAM provides storage for critical data that needs to be retained even when power is lost. An external battery ensures continuous power supply to the IC, allowing it to maintain accurate timekeeping and preserve stored data.
