Description: DS1643 exact functional replacement, plus socket (Same amount of memory, registers, etc.), no slower than 70ns. Compare with my other auction page for an alternate DS1643 smaller vertical physical design....ebay auction ID 296297297593. This chip will be tested in a programmer prior to shipment. Comes with socket and DS1643 module.The DS1643's memory will be zeroed out except for the RTC area which will be programmed with valid data. I am looking for applications that use this module, send me your file and I will program it in. You have to contact me with your application details and dimensions prior to buying this chip. We have to make sure it will physically fit your application. My chip as pictured is taller than the original chip due to the massive battery and better pins. This new part dimensions are:0.6" (15.24mm) tall without socket0.8" (20.32mm) tall with socket0.96" (24.38mm) wide (at the battery) Benefits vs old DS1643:1) Battery is more easily replaceable. (installed battery is 1000mAh) 2) Battery voltage easily measurable. 3) Excluding the battery, this should be UL94V-0 compatible, but no cert supplied. 4) Battery not installed until part is ordered. 5) No more worries about Counterfeit parts from shady sources. 6) This part is not obsolete with no replacement like the original. You can kludge/bodge your existing DS1643 provided only the battery has failed. It’s not too hard to look around and find videos/pictures of how to do it. Drill in exactly the right place...solder...glue, etc. Pretty messy if you ask me and the exact definition of a bodge. And if you’re lucky you won't break a pin off the DS1643 when you’re pulling it out for re-work, which would mean game over on that DS1643. These parts were created after I received a batch of 10 DS1486 from an eBay seller and later determined all 10 parts were bad. The parts even had a date code of 2015 when the seller’s picture clearly showed a 2009 date code. I attempted to return those parts but the seller refused to provide the return to China shipping label and I had to eat the cost of those parts and shipping. So now my rotten experience results in a good solution for those honest eBay buyers. And yes I know we are talking about DS1643 here, but after the DS1486 China debacle, I did not bother trying the experience again on a DS1643. I am not accepting large quantity orders on this part. It’s only available to those hobbyist who really need the parts. Up to 5 days handing time on this item. That will give me enough time to build and test your part before shipment.
