DS1244W-120IND+ Product Details
DS1244W-120IND+ Overview
There is an embedded version of real time clocks in the package 28-DIP Module (0.600, 15.24mm).This package has a package type of Tube.Electrical RTCs such as this have a 2.97V~3.63V supply.In this case, we are dealing with an electrical real time clock that has a type of Phantom Time Chip.It should be noted that the real time clock (RTC) is mounted in the way of Through Hole.Electronic time clocks are recommended to operate at a temperature of -40°C~85°C.If Leap Year, NVSRAM is ensured when operating, then the operation will be successful.There are 28 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 3.3V which is provided to it.A total of 28 pins are attached to this RTCs.There are a family named DS1244 that consarets of the RTCs .In the RTC times, there is a memory of 32KB that is available for storing programs as well as data.As a power supply for the real time clock, a value of 3.3V is used.
