DS1244W-120IND Overview
This real time analog clock can be found in package 28-DIP Module (0.600, 15.24mm).This package has a package type of Tube.It is important to keep in mind that the supply voltage of this electrical RTC is 2.97V~3.63V.This electrical real time clock has the type Phantom Time Chip.A part of this electronic RTC module is mounted in the way of Through Hole.Keeping the temperature at -40°C~85°C is essential to maintaining a safe working environment.If Leap Year, NVSRAM is ensured during operation, then there is no problem.There are 28 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.In the case of this RTC real time clock, there is 3.3V voltage supplied to it.A total of 28 pins are attached to this RTCs.The family RTCs belongs to are DS1244.Under the Timer or RTC subcategory, the RTCs belongs.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 32KB.RTC module mounting type Through Hole is specified.As a power supply for the real time clock, a value of 3.3/5V is used.With 28 pins, it is equipped.RTC time is important to maintain the supply voltage at 3.3V in order to maintain high efficiency.Frequency 120GHz is achievable.
