DS1747WP-120 Overview
34-PowerCap? Module contains real time clocks.There is a way to package time clock in the form of a Tube.In this electrical RTC, the supply voltage is 2.97V~3.63V.Electrical real time clocks of type Clock/Calendar are involved.Surface Mount indicates how this real time clock (RTC) is mounted.Ideally, the operating temperature should be set to 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.It is possible to terminate transmission lines with 34 terminations, which means that the RTC module terminating the line matches its characteristic impedance.There is 3.3V voltage supplied to this RTC real time clock.The RTCs are equipped with the necessary features due to its 34 pins.DS1747 are the family name of RTCs .This electrical digital time clock is powered by a voltage that is 3V at the time of installation.A component such as this is included in the contents of Timer or RTC.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 512KB.There should be no more than a 0.032MHz frequency at real time clocks' output.For the purpose of powering the real time clock, the power supply is set to 3.3V.
