DS1251WP-120IND Product Details
DS1251WP-120IND Overview
real time clocks is located in package 34-PowerCap™ Module.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 Surface Mount is connected to this circuit board.In order to operate properly, the temperature should be -40°C~85°C.During the course of operation, Leap Year, NVSRAM can be ensured.There is the possibility of terminating transmission lines with 34 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 34 pins are included in this product.DS1251 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 3V.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 512KB.Mounting type Surface Mount matches the RTC module.A total of 34 pins are attached to this real time clock.Maintaining the supply voltage at 3.3V is the key to high efficiency.There is a frequency of 120GHz that can be achieved.
