ChipCorders - Whats real, whats not

I have been searching around the web to see what other people are saying about ChipCorders. Unfortunately there is a lot of old data floating around regarding ChipCorders that are no longer available. For example, I found a site with a bunch of PDFs for down load with content I wrote for ISD in the early 1990s. This information is totally out of date and covers some products that haven't been available for 10 years.

Let me get one piece of data out immediately. All of the first generation ChipCorders, are gone. This list includes the ISD1000, ISD1016A, ISD1020A, ISD1420, ISD1416, ISD2560, ISD2590, ISD2575, ISD25120, and the ISD1110 . There are probably more like these I've forgotten about. All of these devices were built in non Winbond fabs and those processes haven't been viable for a number of years. You may find some stock in places, but don't do any new designs with these parts. That supply could disappear and there are no replacements.

If you come upon application data on any of these products, its pretty much worthless. None of the newer Nuvoton products are pin and function compatible with the older ones. If you need to respin a product that used one of these older devices, you will have to do some redesign to use the newer (and available) devices.

Helping with these redesigns is part of the reason I set up this Blog.
