Real-time clock (RTC) ICs are used in electronic circuits to keep track of time relative to the “real” world. Maintaining accurate time is critical, especially under periods of severe system stress or when the power of the main device is off. During these times, RTC ICs must provide robust performance and will often draw power from an auxiliary battery or supercapacitor. As expected, power consumption is a key factor in most real-time clock designs, in addition to accuracy, ruggedness, and small package size. Most modern RTCs reduce the number of pins required by supporting a serial interface. We offer a wide variety of highly accurate, low-power, small-package, and MEMS (microelectromechanical systems)-based real-time clocks to suit any of your solution needs.
Power is reduced with ICs that contain automatic gain control (AGC) circuitry.
MEMs-based RTCs provide improved tolerance to shock and vibration.
The patented SYNC feature allows the RTC to sync with an external signal.
RTCs with integrated crystals or MEMS oscillators offer multiple ways to minimize board space.
