DS1744P-70+ Product Details

DS1744P-70+ Overview


In the 34-PowerCap™ Module package, real time clocks is embedded as a dependency.Tray 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 Surface Mount.There should be 0°C~70°C operating temperature.When operating, electronic time clocks are possible to ensure that Leap Year, NVSRAM, Y2K are maintained.When a transmission line is terminated with 34 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 34 pins are equipped with the RTCs.The family in which RTCs belongs are DS1744.A voltage of 3V is supplied to this electrical digital time clock.RTC times embed a memory of 32KB for storing programs and data.The frequency of real time clocks' output should not exceed 0.032MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 5V.There are 34 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 5V.
