DS1685E-3 Product Details

DS1685E-3 Overview


There is a version of real time clocks in the package 24-TSSOP (0.173, 4.40mm Width).There is a way to package time clock in the form of a Tube.There is a voltage of 2.7V~3.7V when powering this electrical RTC.An electrical real time clock of type Clock/Calendar can be said to be this one.This part is mounted on the systemboard in Surface Mount mode.There should be a temperature of 0°C~70°C during the operation.If Alarm, NVSRAM, Square Wave Output, Y2K is ensured during operation, then there is no problem.Transmission lines with 24 terminations have the characteristic impedance of the RTC module terminating them.This RTC real time clock is supplied with 3V voltage.A total of 24 pins can be found on it.It is important to keep in mind that the supply voltage of this electrical digital time clock is 2.5V~3.7V.In the RTC times you will find a memory of 242B which is available for your programs and data storage.The output frequency of this real time analog clock should not exceed 0.032MHz Hz.1 timers are in the real time clock that outputs a signal in response to an input signal.
