DS1688 Overview
This can be found in the package 28-DIP (0.600, 15.24mm).Tube is the way time clock is packaged.As far as the supply voltage for this electrical RTC is concerned, it is 2.7V~3.3V 4.5V~5.5V.It is a Clock/Calendar type electrical real time clock.In this case, Through Hole is the way this part is mounted on the systemboard.Maintaining a constant temperature of 0°C~70°C is essential for safe operation.When a command are executed, electronic time clocks are possible to maintain Alarm, Leap Year, Square Wave Output, Unique ID in order to maintain the current state.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 memory of 114B is embedded in the RTC times, which can be used to store programs and data.An input signal is received by 1 timers, which output a signal after a preset time.It is also characterized by CAN ALSO OPERATE AT 5V.16 Bits make up this digital time clock.
