Low current consumption
SERIAL-INTERFACE REAL TIME CLOCK MODULE

Overview
This is a real-time clock module of the serial interface system that incorporates a 32.768 kHz crystal oscillator. The real-time clock function incorporates not only a calendar and clock counter for the year, month, day, day of the week, hour, minute, and second, but also a time alarm, interval timer, and time update interruption, among other features. By the battery backup switchover function and the interface power supply input pin, RX6110SA can support various power supply circuitries. All of these many functions are implemented in a thin, compact SOP package, which makes it suitable for various kinds of small electronic devices.
