DS1302ST Product Details

DS1302ST Overview


In the case of 8 terminations, transmission lines have the characteristic impedance of the terminating RTC module.A voltage of 3.3V is applied to this electronic component.As it has 8 pins, it is equipped with the necessary features.The RTCs belongs to the Timer or RTC subcategory.A frequency of 0.032MHz should not be exceeded by real time clocks' output frequency.A power supply of 3/5V is used to power it.When Vsup reaches 5.5V, the maximum supply voltage is reached.In this electrical real time analog clock, there is a uPs/uCs/Peripheral ICs type of TIMER, REAL TIME CLOCK.In order to operate normally, Vsup must remain above 2V.BURST MODE RAM DATA TRANSFER; TIMEKEEPING CURRENT = 0.3UA are other characteristics of it.Below 70°C is the ideal operating temperature.
