DS1689 Overview
There is a version of real time clocks in the package 28-DIP (0.600, 15.24mm).As of Tube, time clock is packaged in this way.2.7V~3.3V 4.5V~5.5V is the supply voltage of this electrical RTC.The electrical real time clock belongs to the type Clock/Calendar.The way this real time clock (RTC) is mounted on the system board is Through Hole.Temperature should be set at 0°C~70°C.During operation, NVSRAM can be guaranteed.28 terminations result in transmission lines having the characteristic impedance of a RTC module terminating them.This RTC real time clock has a voltage supply of 5V which is provided to it.Due to its 28 pins, it has the necessary features.RTCs are a member of the family DS1689.This electrical digital time clock has a 2.5V~3.7V supply voltage.Timer or RTC is the subcategory in which the RTCs belongs.RTC times embed a memory of 114B for storing programs and data.There is a mounting type of Through Hole for this RTC module.A total of 3/5V power supplies are required to operate it.There are 28 pins on it.Following an input signal, there are 1 timers that output a signal at a preset time.Furthermore, AUXILIARY BATTERY I/P; POWER ON INTRPT WITH KICK START; RAM CLEAR I/P; 64-BIT SILICON SERIAL NUMBER are its characteristics.There are 16 bits in this digital time clock.
