High precision, low power consumption, built-in timestamp function! Real-time clock module.
The "RX8901CE" is an RTC (Real-Time Clock) module equipped with a 32.768kHz digital temperature-compensated crystal oscillator (DTCXO). In addition to the basic functions of the RTC, such as time calendar, time alarm, wake-up timer, and time update interrupt, it offers a wealth of features, including the ability to record the occurrence of external or internal events with timestamps up to 32 times. Furthermore, it enables long-term operation of clock calendar information and timestamps for various systems. [Overview] ■ Built-in 32.768 kHz crystal oscillator (frequency accuracy adjusted) ■ Interface type: I2C-Bus interface ■ Low power consumption: 240nA Typ./3V ■ Automatic power switching: Monitors the main power supply and automatically switches to backup power *For more details, please refer to the PDF document or feel free to contact us.
