DS1689SN+ Overview
There is an embedded version of real time clocks in the package 28-SOIC (0.295, 7.50mm Width).Packaged as Tube.Unless otherwise stated, this electrical RTC's supply voltage is 2.7V~3.3V 4.5V~5.5V.There is a type Clock/Calendar for this electrical real time clock.real time clock (RTC)s like this are mounted in the way of Surface Mount.Temperature should be set at -40°C~85°C.As long as NVSRAM is ensured when operating, the system will work properly.Transmission lines with 28 terminations have the characteristic impedance of the RTC module terminating them.This electronic component receives a voltage of 3V.With 28 pins, it is equipped with the necessary functions.The family to which RTCs belongs are DS1689.Its supply voltage is 2.5V~3.7V.There are such RTCs in Timer or RTC subcategory.The RTC times have a memory size of 114B that is available for storing data and programs.A maximum output frequency of 0.032MHz should be maintained by the real time analog clock.The power supply is 3/5V.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.It is also characterized by CAN ALSO OPERATE WITH 5V SUPPLY.With 16 Bits, this digital time clock is designed.
