DS1642-70+ Overview
In the 24-DIP Module (0.600, 15.24mm) package, real time clocks is embedded as a dependency.Tube is the package format.In this electrical RTC, the supply voltage is 4.5V~5.5V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Through Hole.There should be 0°C~70°C operating temperature.When operating, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained.When a transmission line is terminated with 24 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 5V voltage at the moment.A total of 24 pins are equipped with the RTCs.The family in which RTCs belongs are DS1642.RTC times embed a memory of 2KB for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.In order for it to be powered, it requires a power supply of 5V.
