Hi folks, just re-joined. I have a couple of DS1250AB Nonvolatile sram ic'c that i got from Dallas semiconductor over 10 years ago, was planning on using one of them in a circuit i but concerned about its reliability. havent looked at the data sheet in awhile but i believe its internel batttery has a life expectancy of 10 years ? Anyone have any experience in use these or something similar ? I saw something awhile back of a guy that used a dremel tool to cut the package open to replace the battery, or should i just toss it in the garbage ?
