Real-Time Clocks

Real-time clock (RTC) ICs measure time, even when the power of the main device is off. During these times, RTC ICs draw power from an auxiliary battery or supercapacitor. As expected, power consumption is a key factor in most RTC designs, but accuracy and small package size are also important. Most modern RTC ICs reduce package pin count by supporting a serial interface.
Maxim offers a wide range of RTC ICs. View more information on the following types of RTCs.
