RX8130CE B – Serial-Interface RTC-Module, 5,0ppm, I2C, SMT-3225-10

Build-in backup battery charge control functionSERIAL-INTERFACE ƒn REAL TIME CLOCK MODULEOverviewThis 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 backup battery charge control function and the interface power supply input pin, RX8130CE can support various power supply circuitries. All of these many functions are implemented in a thin, compact ceramic package, which makes it suitable for various kinds of small electronic devices.Features:Built in frequency adjusted 32.768 kHz crystal unit.Interface type : I2C-Bus interface (up to 400 kHz)Wide operating voltage range : 1.6V to 5.5VWide timekeeper voltage range : 1.1 to 5.5VAuto power switching function : Switchover by main power supply monitor.Backup battery charge control function : For rechargeable lithium batteries.Low leak current : A leak current from a backup power supply pin. 5nA (Max.)Reset function : At low supply voltage, external reset signal is generated.Low voltage detection : supply voltage and backup voltage detectionTime correction : digital offset functionThe various function include full calendar, alarm, timer, etc.
