DS1338U-33+T&R Product Details

DS1338U-33+T&R Overview


Among the packages 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) is where real time clocks can be found.Basically, time clock is packaged in a way that is equivalent to Tape & Reel (TR).This electrical RTC is powered by a voltage that is 3V~5.5V at the time of installation.The type of this electrical real time clock is Clock/Calendar.The position of this real time clock (RTC) on the system board is indicated by Surface Mount.Temperatures should be kept at -40°C~85°C at all times for safe operation.When running a program, electronic time clocks may be possible to ensure that Leap Year, NVSRAM, Square Wave Output are maintained at all times.In terms of RTCs family, RTCs belongs to DS1338.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 1.3V~3.7V.The RTC times within the system have a memory of 56B available for storing data and programs for the purposes of the system.There is a type of mounting for this RTC module: Surface Mount.8 pins are present on it.RTC time is important to maintain the supply voltage at 3.3V in order to maintain high efficiency.RTC time is recommended that the operating temperature be above -40°C.Lower than 85°C should be the operating temperature.There is minimum supply voltage of 3V required for real time clocks to operate.In this case, 5.5V is the maximum supply voltage.
