Real Time Clocks for Instrument Clusters

Real Time Clocks (RTCs) are IC devices that keep track of time. A typical RTC can provide the time of day as well as the date via a serial bus such as I2C or SPI. Although similar in many ways, RTCs should not be confused with clock generators, which are used to synchronize various parts of a circuit.
