DS1344E-33+ Overview


There is an embedded version in the package 20-TSSOP (0.173, 4.40mm Width).Tube is the packaging method.Electrical RTCs such as this have a 3V~5.5V supply.This electrical real time clock has the type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).There should be a temperature of -40°C~85°C during the operation.There is a way to make sure that Alarm, Leap Year, NVRAM, Square Wave Output, Trickle Charger is maintained when operating if desired.There are 20 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.It should be noted that this RTC real time clock is being supplied with 3.3V voltage at the moment.The reason for this is that, due to the fact that it has 20 pins, it has the necessary features.In terms of RTCs family, RTCs belongs to DS1344.Note that the supply voltage is 1.3V~5.5V for this electrical digital time clock.There are such RTCs in Timers or RTCs subcategory.The RTC times have a memory size of 96B that is available for storing data and programs.A frequency of 4MHz should not be exceeded by real time clocks' output frequency.Mounting type is Surface Mount.There are 20 pins on it.1 timer real time clocks send out a signal at a preset time based on input signals.RTC time is essential that the supply voltage remain at 3.3V for maximum efficiency.
