DS1689 Overview
In the 28-DIP (0.600, 15.24mm) package, real time clocks is embedded as a dependency.A Tube package is used to package time clock.The supply voltage of this electrical RTC is 2.7V~3.3V 4.5V~5.5V.An electrical real time clock of this type is called a Clock/Calendar.On the system board, this real time clock (RTC) is mounted in Through Hole.Ideally, the operating temperature should be 0°C~70°C.When operating, electronic time clocks are possible to make sure that NVSRAM remains constant in the process.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 5V voltage.It is equipped with the necessary features since it has 28 pins.This electrical digital time clock is powered by a voltage that is 2.5V~3.7V at the time of installation.RTC times embed a memory of 114B for storing programs and data.When an input signal is received, 1 timers are used to output a signal at a preset time.It is also characterized by AUXILIARY BATTERY I/P; POWER ON INTRPT WITH KICK START; RAM CLEAR I/P; 64-BIT SILICON SERIAL NUMBER.A 16 bit digital time clock has been designed.
