DS1390U-18+ Overview
A package named 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) contains real time clocks.Tube is the packaging method.There is 1.71V~1.89V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~85°C is the operating temperature.When operating, you can ensure Alarm, Leap Year, Square Wave Output, Trickle-Charger.A transmission line can have a 10 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 1.8V voltage supplied to it.The RTCs are equipped with 10 pins.DS1390 is the family name of this object.This electrical digital time clock is powered by 1.3V~3.7V voltage.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Surface Mount.10 pins are attached to it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.Optimal efficiency requires a supply voltage of 1.8V.
