DS1685Q-3 Overview
In package 28-LCC (J-Lead), real time clocks is located.Time clock is packaged in the manner of Tube.There is a voltage of 2.7V~3.7V when powering this electrical RTC.The type of this electrical real time clock is Clock/Calendar.There is an real time clock (RTC) mounted in the way of Surface Mount.0°C~70°C should be the operating temperature.If Alarm, NVSRAM, Square Wave Output, Y2K is ensured during operation, then there is no problem.There is the possibility of terminating transmission lines with 28 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.This RTC real time clock is supplied with 3V voltage.With 28 pins, it is equipped with the necessary functions.DS1685 are the family RTCs belongs to.This electrical digital time clock is powered by 2.5V~3.7V voltage.Timer or RTC includes this part.In the RTC times, there is a memory of 242B that is available for storing programs as well as data.The frequency of real time clocks' output should not exceed 0.032MHz.RTC module mounting type Surface Mount is specified.In order for it to be powered, it requires a power supply of 3V.There are 28 pins on it.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.RTC time is essential that the supply voltage remain at 3V for maximum efficiency.
