DS1339U-33+T Overview
There are 8 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.The supply voltage of this RTC real time clock is 3.3V.It is equipped with 8 pins.Real time clocks' output frequency should not exceed 0.032MHz.It operates from 3.3V power supplies.There are 1 timers, which are control real time clocks that output a signal at a preset time after an input signal is received.The maximal supply voltage (Vsup) reaches 3.63V.The uPs/uCs/Peripheral ICs type of this electrical real time analog clock is TIMER, REAL TIME CLOCK.The supply voltage (Vsup) should be kept above 2.97V for normal operation.The operating temperature should be kept below 85°C.
