Description
Alarm clock ICs typically include a real-time clock (RTC) module that keeps track of time and date. They may have built-in oscillators or rely on an external crystal oscillator for accurate timekeeping. These ICs often provide options for setting multiple alarms, snooze functionality, and customizable alarm tones.
