UNIT RTC is a programmable real-time clock module, integrated HYM8563 low-power CMOS real-time clock/calendar chip, using I2C communication interface, full-coverage case can effectively protect the circuit, making its operation more stable. Applicable to a variety of embedded devices, instruments and instruments as a system clock.
Most MCUs are built-in timers, which usually start working automatically when the hardware is powered on, and reset when the hardware is powered off. The built-in timer can handle some simple timing tasks, but if we want to implement data timestamp recording, clock, alarm clock and other time-span functions, a system power-independent clock RTC is the best choice.
