RX8900CE UA Serial interface RTC modules, 3.4ppm, I²C, SMT-3225-10

I2C bus interface RTC module

Overview This module is an I2C bus interface-compliant real-time clock which includes a 32.768 kHz DTCXO. In addition to providing a calendar (year, month, date, day, hour, minute, second) function + a clock counter function, it provides an abundance of other functions including an alarm function, Wakeup timer function, time update interrupt function + 32.768 kHz output function. Thanks to the battery backup switchover function + the interface power supply input pin, RX8900 can support various power supply circuitries. C-MOS process for low current consumption, which enables long-term battery back-up.
