A package named PDIP contains real time clocks.A transmission line can have a 8 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 5V voltage supplied to it.The RTCs are equipped with 8 pins.Programs and data can be stored in the 8B memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.8 pins are attached to it.6V is the maximum supply voltage (Vsup).An electrical real time analog clock like this has a type TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.As a rule of thumb, the supply voltage (Vsup) should never be below 2.5V.
