DS1344D-3+T&R Product Details

DS1344D-3+T&R Overview


There is an embedded version of real time clocks in the package 14-WFDFN Exposed Pad.This package has a package type of Digi-Reel®.Electrical RTCs such as this have a 2.7V~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 -40°C~85°C.If Alarm, Leap Year, NVRAM, Square Wave Output, Trickle Charger is ensured when operating, then the operation will be successful.There are a family named DS1344 that consarets of the RTCs .In this electrical digital time clock, the supply voltage is 1.3V~5.5V.In the RTC times, there is a memory of 96B that is available for storing programs as well as data.In this case, the RTC module is mounted in the way of Surface Mount.A total of 14 pins are equipped with the real time clock.RTC time is essential that the supply voltage remain at 3V for maximum efficiency.Operating temperatures should be greater than -40°C.A temperature lower than 85°C should be used for operating.
