RX8900CE UA - Serial-Interface RTC-Module, 3,4ppm, I²C, SMT-3225-10

I2C-Bus Interface Real-time Clock ModuleOverviewThis 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 and a clock counter function, this module provides an abundance of other functions including an alarm function, Wakeup timer function, time update interrupt function, and 32.768 kHz output function. By the battery backup switchover function and the interface power supply input pin, RX8900 can support various power supply circuitries. The devices in this module are fabricated via a C-MOS process for low current consumption, which enables long-term battery back-up.Features:Features built-in 32.768 kHz DTCXO, High Stability.Supports I2C-Bus's high-speed mode (Up to 400 kHz)Alarm interrupt function for day, date, hour, and minute settingsWakeup timer interruptionTime update interrupt function (Seconds, minutes)Temperature compensated 32.768 kHz output with OE function (FOE and FOUT pins)Auto correction of leap years (from 2000 to 2099)Wide interface voltage range: 2.5 V to 5.5 VWide time-keeping voltage range:1.6 V to 5.5 VLow current consumption: 0.70µA / 3 V (Typ.)Built-in Backup switchover circuit (trickle charge)
