DS1251W-120+ Product Details

DS1251W-120+ Overview


real time clocks is located in package 32-DIP Module (0.600, 15.24mm).As of Tube, time clock is packaged in this way.There is 2.97V~3.63V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Phantom Time Chip type.The real time clock (RTC) that is mounted in the way of Through Hole is connected to this circuit board.In order to operate properly, the temperature should be 0°C~70°C.During the course of operation, Leap Year, NVSRAM can be ensured.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.DS1251 are the family name of RTCs .For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 512KB.Mounting type Through Hole matches the RTC module.For powering the real time clock, a power supply with a voltage of 3.3V is used.A total of 32 pins are attached to this real time clock.There is a frequency of 120GHz that can be achieved.
