What are Real Time Clocks?
A Real Time Clock, abbreviated as RTC, is a computer clock that is an electrical component designed to work as an integrated circuit. These devices are manufactured in an innovative way to keep track of time. In particular, they are designed to be used with streaming or real-time data. Therefore, the names are given. The computer's motherboard has an integrated real-time clock that keeps track of all the related things, as the calendar and alarm are also incorporated into this category.
How do Real-Time Clocks function?
The memory is fixed on top of the clock system that stores system routine activities and descriptions and configures the values, such as the current time value. The information that is embedded in the Real-time clocks is defined by a microprocessor, which is commonly distributed over a serial interface that supports the reliability and performance of the software that is based on time. RTCs frequently run on a lithium battery supply but can also function on regular power because they are made to operate with extremely low power consumption.
When a system is down, it can still operate and produce real-time data thanks to this power source. The power source for the most recent RTC devices is a rechargeable super-capacitor that is soldered to the board. Real-Time Clocks with synchronization to an external signal, like a power line frequency that has been compensated, are available. It enables the tool to deliver a precise result without an internal temperature correction system.
RTC Time Values
- Seconds
- Minutes
- Hours

- Year
What are the applications of real-time clocks?
These devices are available on any kind of electronic equipment that needs to keep track of accurate time in the application or system. This function is very reliable and secure even when the system is powered off, still maintains accurate time, and has the potential to store sufficient energy to be used even if the power is not connected for a long time. Real-time clocks are typically embedded in:
- Personal Computers
- Embedded systems, and
- Servers.
