DS1244Y-70+ Overview
There is a package 28-DIP Module (0.600, 15.24mm) that contains real time clocks.The package is in the form of Tube.4.5V~5.5V is the supply voltage of this electrical RTC.An electrical real time clock of this type is called a Phantom Time Chip.The way this real time clock (RTC) is mounted on the system board is Through Hole.In order to be safe, electronic time clocks are imperative that the temperature are kept at 0°C~70°C at all times.In order to ensure Leap Year, NVSRAM when operating, a certain value has to be set.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It is possible to see 5V voltage being supplied to this RTC real time clock.28 pins are present on it.In terms of RTCs family, RTCs belongs to DS1244.This component can be found in Timer or RTC.In the RTC times, there is a memory of 32KB that is available for storing programs as well as data.A Through Hole mounting type is assigned to the RTC module.As a power supply for the real time clock, a value of 5V is used.There are 28 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. Optimal efficiency can be achieved by maintaining the supply voltage at 5V.70GHz is the maximum frequency that can be achieved.
