DS1689SN Overview
In the 28-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded as a dependency.The package is packaged in the way of Tube.It requires a voltage of 2.7V~3.3V 4.5V~5.5V to be supplied.Electrical real time clocks of this type are Clock/Calendar.This part is mounted on the systemboard in Surface Mount mode.-40°C~85°C should be the operating temperature.Electronic time clocks are possible to guarantee NVSRAM when operating.When a transmission line is terminated with 28 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It is possible to see 3V voltage being supplied to this RTC real time clock.A total of 28 pins can be found on it.In terms of RTCs family, RTCs belongs to DS1689.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.5V~3.7V.Under the Timer or RTC subcategory, the RTCs belongs.For storing data and programs, the RTC times embed a memory of 114B.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.There is a mounting type Surface Mount specified for the RTC module.There is a power supply of 3/5V used to power the real time clock.It is equipped with 28 pins.An input signal is received by 1 timers, which output a signal after a preset time.The CAN ALSO OPERATE WITH 5V SUPPLY characteristics are also present.16 Bits make up this digital time clock.
