Real Time Clock (RTC) ICs are timing components used to maintain accurate time and calendar information in electronic systems, even when the main power is turned off. They are widely used in embedded systems, industrial control, consumer electronics, communication equipment, medical devices, automotive electronics, IoT products, meters and data logging applications.

This category includes real time clock ICs, battery-backed RTCs, low-power RTCs, I2C RTCs, SPI RTCs, calendar clock ICs and related clock/timing components. These devices are commonly selected based on timekeeping accuracy, backup power support, interface type, alarm functions, operating voltage, current consumption, package type and application requirements.

TomatoElec supplies original Real Time Clock RTC ICs from recognized semiconductor manufacturers such as Microchip, NXP, STMicroelectronics, Renesas, Texas Instruments, Analog Devices, onsemi, Infineon and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
