DS1689S Overview
The package 28-SOIC (0.295, 7.50mm Width) contains real time clocks.Tube is the way time clock is packaged, which is the way time clock is intended to be.To supply this electrical RTC, a voltage of 2.7V~3.3V 4.5V~5.5V is required.This electrical real time clock belongs to the Clock/Calendar category.This real time clock (RTC) is mounted in the way of Surface Mount.A safe operation requires a temperature of 0°C~70°C at all times.When running a program, electronic time clocks may be possible to ensure that NVSRAM are maintained at all times.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.A voltage of 3V is applied to this electronic component.A total of 28 pins are attached to this RTCs.The family to which RTCs belongs are DS1689.Its supply voltage is 2.5V~3.7V.RTCs in the Timer or RTC subcategory are available.For storing the programs and data, the RTC times have an embedded memory of 114B for storing data and programs.A frequency above 0.032MHz should not be used for real time clocks' output.Mounting type is Surface Mount.There is a power supply of 3/5V used to power the real time clock.It is equipped with 28 pins.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.Additionally, it has CAN ALSO OPERATE WITH 5V SUPPLY.A 16 bit digital time clock is designed for this application.
