DS1744P-70 Overview


In package 34-PowerCap? Module, real time clocks is located.Tube is the way time clock is packaged.Providing this electrical RTC with a voltage of 4.5V~5.5V is required.The electrical real time clock belongs to the type Clock/Calendar.This part is mounted on the systemboard in the way indicated by Surface Mount.As far as the operating temperature are concerned, electronic time clocks should be 0°C~70°C.When a command are executed, electronic time clocks are possible to maintain Leap Year, NVSRAM, Y2K in order to maintain the current state.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.Obviously, a voltage of 5V is being supplied to this electronic component.It is equipped with the necessary features since it has 28 pins.This electrical digital time clock has a supply voltage of 3V.For storing the programs and data, the RTC times have an embedded memory of 32KB for storing data and programs.There should be no more than a 0.032MHz frequency at real time clocks' output.There are also A POWERCAP MODULE CONTAINING CRYSTAL AND BATTERY REQUIRED characteristics.
