The RX8900CE:UBB is a real-time clock (RTC) module featuring an I¬=C-Bus interface, designed for high stability and low power consumption. It operates within a voltage range of 2.5 V to 5.5 V and includes a built-in 32.768 kHz crystal oscillator with temperature compensation. The device supports automatic power switching to a backup supply when the main voltage drops below 1.9 V, ensuring continuous timekeeping. This RTC offers various functionalities, including a selectable clock output frequency (32.768 kHz, 1024 Hz, or 1 Hz), a programmable wakeup timer with intervals from 244 ¬µs to 2.8 days, and an alarm function that can be set from day to minute. The RX8900CE also includes an embedded temperature sensor for monitoring temperature data. With a compact size of 3.2 x 2.5 mm and a maximum height of 1.0 mm, the RX8900CE is suitable for space-constrained applications. It operates effectively across a temperature range of -40 ¬?C to +85 ¬?C and exhibits stability characteristics of ¬±5.0 x 10^-6 over the specified temperature range. This product is ideal for applications requiring reliable timekeeping and low power consumption, such as automotive electronics and portable devices.
