In the 18-SOX, 18-SOIC with Crystal (7.5mm Width) package, real time clocks is embedded as a dependency.Tape & Reel (TR) is the package format.In this electrical RTC, the supply voltage is 2.7V~5.5V.Clock/Calendar is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be -40°C~85°C operating temperature.When operating, electronic time clocks are possible to ensure that Alarm, Leap Year, Square Wave Output, Watchdog Timer are maintained.When a transmission line is terminated with 18 terminations, it means that the RTC module that terminates the line matches its characteristic impedance.It should be noted that this RTC real time clock is being supplied with 5V voltage at the moment.A total of 18 pins are equipped with the RTCs.The family in which RTCs belongs are M41T81.A voltage of 2V~3.5V is supplied to this electrical digital time clock.The frequency of real time clocks' output should not exceed 0.032MHz.Mounting type Surface Mount is chosen for the RTC module.In order for it to be powered, it requires a power supply of 3/5V.There are 18 pins on it.When an input signal is received, 1 timers are used to output a signal at a preset time.
