DS1747P-70IND+ Product Details
DS1747P-70IND+ Overview
There is an embedded version of real time clocks in the package 34-PowerCap™ Module.This package has a package type of Tray.Electrical RTCs such as this have a 4.5V~5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of -40°C~85°C.If Leap Year, NVSRAM, Y2K is ensured when operating, then the operation will be successful.There are 34 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 5V which is provided to it.A total of 34 pins are attached to this RTCs.There are a family named DS1747 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 3V.In the RTC times, there is a memory of 512KB that is available for storing programs as well as data.Ensure that the output frequency does not exceed 0.032MHz.As a power supply for the real time clock, a value of 5V is used.
