DS1338U-33 Product Details

DS1338U-33 Overview


real time clocks is located in package 8-TSSOP, 8-MSOP (0.118, 3.00mm Width).As of Tube, time clock is packaged in this way.There is 3V~5.5V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Clock/Calendar 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, Square Wave Output can be ensured.There is the possibility of terminating transmission lines with 8 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 8 pins are included in this product.As far as the supply voltage for this electrical digital time clock is concerned, it is 1.3V~3.7V.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 56B.There should be no frequency greater than 0.032MHz in real time clocks' output.1 timer real time clocks send out a signal at a preset time based on input signals.
