A real-time clock (RTC) is an IC equipped with a timekeeping function, used in systems that need to keep time even when the main device (such as an MCU) is powered off.
ABLIC's real-time clocks achieve longer battery life with an ultra-low current consumption of 0.25μA. Furthermore, they feature high-accuracy clock correction with a minimum resolution of 1ppm, a constant 32kHz output, an expansion alarm, a 24-bit up counter, and an ultra-small 2.46×1.97mm package, enabling one of the world's smallest real-time clocks. As a result, they offer time management solutions for various applications, including housing and industrial equipment.
