The RX4901CE is a RTC module with an integrated 32.768 kHz digital temperature compensated crystal oscillator (DTCXO). It includes various functions such as a time stamp function that can record up to 32 dates and times when an external or internal event occurs, as well as the basic RTC functions such as time and calendar, time alarm, wakeup timer, and time update interrupts. With the combination of an auto power switching function, which includes a control circuit to prevent reverse current to the main power supply, a continuous temperature-corrected 32.768 kHz clock generation, and Seiko Epson's original low current consumption technology, the RX4901CE realizes long battery life on various systems.
