DS1747WP-120IND+ Product Details
DS1747WP-120IND+ Overview
You can find real time clocks in package 34-PowerCap™ Module among the other packages that are available.Tray is the way time clock is packaged, which is the way time clock is intended to be.It requires a voltage of 2.97V~3.63V to be supplied.Electrical real time clocks of type Clock/Calendar are involved.This electronic component has been mounted in the way of Surface Mount.In order to be safe, electronic time clocks are imperative that the temperature are kept at -40°C~85°C at all times.When a command are executed, electronic time clocks are possible to maintain Leap Year, NVSRAM, Y2K in order to maintain the current state.A transmission line with 34 terminations possesses the characteristic impedance of the RTC module terminating it.RTC real time clocks like this have a 3.3V supply voltage.The RTCs are equipped with the necessary features due to its 34 pins.As far as the family are concerned, RTCs are part of DS1747.This electrical digital time clock's supply voltage is 3V.In the real time analog clocks, the available memory size is 512KB.The frequency of real time clocks' output should not be higher than 0.032MHz.As a power supply for the real time clock, a value of 3.3V is used.
