The RX4111CE A3 is a real-time clock module featuring an SPI-Bus interface and a built-in frequency-adjusted 32.768 kHz crystal unit. It operates within a temperature range of -40 ¬8C to +105 ¬8C and has a low backup current consumption of 100 nA at 3 V. The module includes an auto power switching function that automatically transitions to a backup power supply when the VDD voltage drops below 1.2 V. Key functionalities include a time stamp feature that can record time from year to 1/256 seconds, an interrupt output for wake-up signals every minute or second, and programmable alarm interruptions down to the second. The RX4111CE A3 also supports a selectable clock output frequency of 32.768 kHz, 1024 Hz, or 1 Hz, and offers a wakeup timer function with a selectable range from 244 ¬µs to 32 years. The device is designed for applications requiring reliable timekeeping and low power consumption, making it suitable for various electronic projects.
