DS1685QN-5 Overview
This can be found in the package 28-LCC (J-Lead).Tube is the way time clock is packaged.Providing this electrical RTC with a voltage of 4.5V~5.5V is required.An electrical real time clock of this type is called a Clock/Calendar.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.Temperature should be set at -40°C~85°C.During operation, the value of Alarm, NVSRAM, Square Wave Output, Y2K can be ensured.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This RTC real time clock has a voltage of 5V.As it has 28 pins, it is equipped with the necessary features.A voltage of 2.5V~3.7V is supplied to this electrical digital time clock.It should be noted that the RTC times embed a memory of 242B which is usable for storing programs and data as well.0.032MHz should be the maximum output frequency.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.
