DS1643P-70 Product Details

DS1643P-70 Overview


There is a version of real time clocks in the package 34-PowerCap™ Module.There is a way to package time clock in the form of a Tube.There is a voltage of 4.5V~5.5V when powering this electrical RTC.An electrical real time clock of type Clock/Calendar can be said to be this one.This part is mounted on the systemboard in Surface Mount mode.There should be a temperature of 0°C~70°C during the operation.If Leap Year, NVSRAM is ensured during operation, then there is no problem.Transmission lines with 34 terminations have the characteristic impedance of the RTC module terminating them.This RTC real time clock is supplied with 5V voltage.A total of 34 pins can be found on it.It is important to keep in mind that the supply voltage of this electrical digital time clock is 3V.In the RTC times you will find a memory of 8KB which is available for your programs and data storage.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.
