What are Real Time Clocks ?
Real Time Clocks (RTCs) are integrated circuits designed to keep track of the current time and date, even when the main power is off. They are widely used in applications such as timers, clocks, and scheduling devices in consumer electronics and industrial systems. Important specifications for selecting RTCs include Current, which affects power consumption; Date Format, which determines how the time is displayed; and Operating Temperature, which ensures reliable performance in different environments. Procurement teams should validate lifecycle status and consider alternate-source options to mitigate sourcing risks.
