DS1685QN-3+ Overview


In the 28-LCC (J-Lead) package, real time clocks is embedded as a dependency.As of Tube, time clock is packaged in this way.Unless otherwise stated, this electrical RTC's supply voltage is 2.7V~3.7V.The type of this electrical real time clock is Clock/Calendar.A part of this electronic RTC module is mounted in the way of Surface Mount.Ideally, the operating temperature should be set to -40°C~85°C.In order to ensure Alarm, NVSRAM, Square Wave Output, Y2K when operating, a certain value has to be set.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 28 termination.This RTC real time clock's supply voltage is 3V.It has a total of 28 pins on it.As a member of the DS1685 family, RTCs belongs to them.2.5V~3.7V is the supply voltage of this electrical digital time clock.This component can be found in Timer or RTC.The RTC times embed a memory of 242B available for storing programs and data.It should not exceed 0.032MHz as the output frequency of the real time analog clock.For powering the real time clock, a power supply with a voltage of 3V is used.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.
