This product is a CMOS real-time clock IC with I2C bus serial interface and voltage monitoring function
The RV5C386A is a CMOS real-time clock IC designed for serial transmission of time and calendar data to a CPU via two signal lines, SCL and SDA. It supports time counters for hours, minutes, and seconds, as well as calendar counters for years, months, days, and weeks in BCD format. The device includes features such as a periodic interrupt circuit with selectable ranges from 0.5 seconds to 1 month, two alarm circuits, and a 32-kHz clock output function.
