DS1688 Product Details
DS1688 Overview
28-DIP (0.600, 15.24mm) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.7V~3.3V 4.5V~5.5V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Through Hole.Electronic time clocks should be 0°C~70°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Alarm, Leap Year, Square Wave Output, Unique ID when operating.Transmission lines can be terminated with 28 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 5V supplied to it.28 pins are present on it.DS1688 are RTC s family.A memory of 114B is embedded into the RTC times for storing programs and data.There is a mounting type of Through Hole for this RTC module.The power supply is 3/5V.With 28 pins, it is equipped.1 timers are in the real time clock that outputs a signal in response to an input signal.In addition, it is characterized by CAN ALSO OPERATE AT 5V.16 Bits are used in the design of this digital time clock.
