DS1251W-120IND Overview
32-DIP Module (0.600, 15.24mm) contains real time clocks.Packaged as Tube.It is important to keep in mind that the supply voltage of this electrical RTC is 2.97V~3.63V.Electrical real time clock type Phantom Time Chip.The position of this real time clock (RTC) on the system board is indicated by Through Hole.A safe operation requires a temperature of -40°C~85°C at all times.As long as Leap Year, NVSRAM is ensured when operating, the system will work properly.There is the possibility of terminating transmission lines with 32 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 3.3V.A total of 32 pins are included in this product.In terms of RTCs family, RTCs belongs to DS1251.It is included as part of Timer or RTC.It should be noted that the RTC times embed a memory of 512KB which is usable for storing programs and data as well.It appears that the RTC module's mounting type is Through Hole.32 pins are attached to it.Optimal efficiency can be achieved by maintaining the supply voltage at 3.3V.There is 120GHz frequency that can be achieved.
