DS1344E-18+ Product Details

DS1344E-18+ Overview


There is an embedded version in the package 20-TSSOP (0.173, 4.40mm Width).Packaged as Tube.This electrical RTC is powered by 1.71V~5.5V voltage.This electrical real time clock is of type Clock/Calendar.Surface Mount is the way to mount this real time clock (RTC).A temperature of -40°C~85°C should be used for operation.During operation, Alarm, Leap Year, NVRAM, Square Wave Output, Trickle Charger can be guaranteed.The 20 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.It is possible to see 1.8V voltage being supplied to this RTC real time clock.20 pins are attached to it.RTCs are a member of the family DS1344.Its supply voltage is 1.3V~5.5V.In these RTC times, there is a memory of 96B where data and programs can be stored.There should be no more than 4MHz frequency in real time clocks' output.This RTC module has a mounting type of Surface Mount.20 pins are present on it.In this system, there are 1 timers, which are real time clocks that output a signal at a preset time after an input signal is received.RTC time is important to maintain the supply voltage at 1.8V in order to maintain high efficiency.
