RS4TC8900Q Temperature Compensated Real Time Clock

PublishTime：2024-10-30

■Description:
●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 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, RS4TC8900Q can support various power supply circuitries.
●The devices in this module are fabricated via a CMOS process for low current consumption, which enables long-term battery back-up.
●RS4TC8900Q is suitable for automotive applications requiring specific change control.
