There is an embedded version of real time clocks in the package 28-DIP (0.600, 15.24mm).This package has a package type of Tube.Electrical RTCs such as this have a 3V~3.6V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Through Hole.Electronic time clocks are recommended to operate at a temperature of -40°C~85°C.If Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K is ensured when operating, then the operation will be successful.There are 28 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 3.3V which is provided to it.A total of 28 pins are attached to this RTCs.There are a family named DS1501 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 2.5V~3.7V.In the RTC times, there is a memory of 256B that is available for storing programs as well as data.Ensure that the output frequency does not exceed 0.032MHz.As a power supply for the real time clock, a value of 3.3V is used.Following an input signal, there are 1 timers that output a signal at a preset time.
