DS1685QN-3 Overview


Real time clocks is embedded in the 28-LCC (J-Lead) package.This package has a package type of Tube.A voltage of 2.7V~3.7V is supplied to this electrical RTC.The type of this electrical real time clock is Clock/Calendar.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be a temperature of -40°C~85°C during the operation.When operating, electronic time clocks are possible to make sure that Alarm, NVSRAM, Square Wave Output, Y2K remains constant in the process.28 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.RTC real time clocks such as this one are powered by 3V voltage.The reason for this is that, due to the fact that it has 28 pins, it has the necessary features.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.5V~3.7V.The RTC times have a memory size of 242B that is available for storing data and programs.Real time clocks' output frequency should not exceed 0.032MHz.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.
