The SD3078 Clock Module is a precision real-time clock (RTC) solution, designed to keep time accurately across a wide temperature range. With a built-in crystal oscillator and I²C interface, it’s fully compatible with the 8025 pin layout, making it easy to integrate into most systems. It delivers ±3.8PPM accuracy at room temperature and includes full temperature compensation. This module features low power consumption, a 32.768kHz square wave output, 70-byte data register, battery voltage monitoring, and even a built-in charging function. Whether for microcontroller timing or embedded systems, the SD3078 keeps your devices on schedule—reliably, efficiently, and with minimal fuss.
