DS1302S+ Product Details

DS1302S+ Overview


There is an embedded version of real time clocks in the package 8-SOIC (0.209, 5.30mm Width).This package has a package type of Tube.Electrical RTCs such as this have a 2V~5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of 0°C~70°C.If Leap Year, NVSRAM, Trickle-Charger is ensured when operating, then the operation will be successful.There are 8 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 3.3V which is provided to it.A total of 8 pins are attached to this RTCs.There are a family named DS1302 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 2V~5.5V.In the RTC times, there is a memory of 31B that is available for storing programs as well as data.Ensure that the output frequency does not exceed 0.032MHz.As a power supply for the real time clock, a value of 3/5V is used.A total of 8 pins are equipped with the real time clock.Furthermore, BURST MODE RAM DATA TRANSFER; TIMEKEEPING CURRENT = 0.3UA are its characteristics.
