DS1643-100+ Overview
There is a version of real time clocks in the package 28-DIP Module (0.600, 15.24mm).There is a packaging method that is similar to Tube.It requires a voltage of 4.5V~5.5V to be supplied.The electrical real time clock belongs to the type Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Through Hole.In order to operate properly, the temperature should be 0°C~70°C.As long as Leap Year, NVSRAM is ensured when operating, the system will work properly.There is the possibility of terminating transmission lines with 28 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.5V voltage is present on this electronic component.A total of 28 pins can be found on it.DS1643 is the family name of this object.Timer or RTC includes this part.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 8KB.There should be no frequency greater than 0.032MHz in real time clocks' output.It operates from 5V power supplies.When an input signal is received, 1 timers are used to output a signal at a preset time.
