DS1244W-120 Overview
28-DIP Module (0.600, 15.24mm) contains real time clocks.There is a packaging method that is similar to Tube.Its supply voltage is 2.97V~3.63V.It is a Phantom Time Chip type electrical real time clock.The real time clock (RTC) that is mounted in the way of Through Hole is connected to this circuit board.Ideally, the operating temperature should be 0°C~70°C.Electronic time clocks are possible to guarantee Leap Year, NVSRAM when operating.There is the possibility of terminating transmission lines with 28 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.3.3V voltage is present on this electronic component.There are 28 pins on it.DS1244 is the family name of this object.Under the Timer or RTC subcategory, the RTCs belongs.A real time analog clock's memory size is 32KB, which is available for storing programs and data.The RTC module is mounted with mounting type Through Hole.For the purpose of powering the real time clock, the power supply is set to 5V.There are 28 pins on it.There are also ALSO REQUIRES 4.5 TO 5.5 VOLTS characteristics.Frequency 120GHz is achievable.
