DS1685Q-3 Overview
In package 28-LCC (J-Lead), real time clocks is located.Time clock is packaged in the manner of Tube.This electrical RTC receives its power from the 2.7V~3.7V supply voltage.There is a type of electrical real time clock Clock/Calendar associated with this real time clock.real time clock (RTC)s like this are mounted in the way of Surface Mount.Temperature should be set at 0°C~70°C.During the course of operation, Alarm, NVSRAM, Square Wave Output, Y2K can be ensured.Transmission lines with 28 terminations have the characteristic impedance of the RTC module terminating them.This RTC real time clock has a voltage of 3V.The RTCs are equipped with the necessary features due to its 28 pins.Note that the supply voltage is 2.5V~3.7V for this electrical digital time clock.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.Upon receiving an input signal, 1 timers output a signal at a preset time.
