Micro Crystal RV-8063-C8 Real-Time Clock (RTC) Modules incorporate an integrated CMOS circuit with an XTAL. These SMD RTC modules also incorporate an offset register and compensate frequency deviation of the 32.768kHz clock. The RV-8063-C8 RTC modules transfer all addresses and data serially via a Serial Peripheral Interface (SPI-bus) with a 7Mbit/s maximum data rate. These modules feature internal Power-On Reset (POR), oscillator stop detection function, and countdown timer interrupt function.
