DS1743W-150+ Overview
Tube is the package format.When a transmission line is terminated with 28 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 3.3V voltage at the moment.A total of 28 pins are equipped with the RTCs.The frequency of real time clocks' output should not exceed 0.032MHz.In order for it to be powered, it requires a power supply of 3.3V.There are 28 pins on it.It reaches a maximum supply voltage of 3.63V (Vsup).In this electrical real time analog clock, uPs/uCs/peripheral ICs are of the type TIMER, REAL TIME CLOCK.In order to maintain normal operation, the supply voltage (Vsup) must be kept above 2.97V.Under 70°C, the operating temperature should be maintained.
