DS1338Z-3+ Overview
real time clocks is located in package 8-SOIC (0.154, 3.90mm Width).As of Tube, time clock is packaged in this way.There is 2.7V~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 3V.A total of 8 pins are included in this product.DS1338 are the family name of RTCs .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.Mounting type Surface Mount matches the RTC module.For powering the real time clock, a power supply with a voltage of 3V is used.A total of 8 pins are attached to this real time clock.1 timer real time clocks send out a signal at a preset time based on input signals.Maintaining the supply voltage at 3V is the key to high efficiency.
