Automatically switch to backup power while monitoring the main power supply! Equipped with various functions.
The "RX4111CE" is a real-time clock module with a built-in crystal oscillator, featuring power switching functions and clock output functions. With the wake-up timer function, timer durations can be set from 244μs to 32 years, selectable from source clock options of 1/60Hz, 1Hz, 64Hz, and 4096Hz. Upon timer completion, it outputs an interrupt from the INT terminal and then auto-releases. Additionally, this operation can be auto-repeated at a specified cycle, allowing it to be used similarly to a watchdog timer. 【Overview】 ■ Built-in 32.768kHz crystal oscillator (frequency accuracy adjusted) ■ Interface method: SPI-Bus interface, 4-wire ■ Low power consumption: 100nA Typ./3V ■ Automatic power switching: Monitors main power and automatically switches to backup power ■ Timestamp: Records timestamp 8 times (from year to 1/256 second) *For more details, please refer to the PDF document or feel free to contact us.
