Real Time Clocks (RTC)

Real Time Clocks (RTC)

RTC modules are used to integrate Real Time Clocks into a computer or operating system. A real-time clock measures the physical time and, thanks to its own energy storage, continues to record the time even when the device is switched off. In order to guarantee this function for as long as possible, RTC modules usually operate with very low power consumption.

Within a PC, the real-time clock functions as a circuit, this is set up using the RTC modules. Basically a counter is running which is clocked by an oscillating crystal. The register statuses are read out by a connected processor or microcontroller for further processing. The respective operating system converts the information into date and time and also calculates time zones and leap years. After switching on, this software must first be synchronized with the hardware.

RTC modules are used to record the time, especially in the following devices:

  • PCs
  • Radio alarm clock
  • Microwaves
  • Control units of heating installations

RTC modules are usually an integral part of the motherboard of a computer. Otherwise Bürklin offers you a wide range of high-quality RTC modules from various manufacturers as well as other network and PC accessories.
