Is the currently supported 27 series devices.

DIP28 requires a DIP28 socket (or you can make your own), but you cant put a DIP28 into a DIP32 socket. We actually have DIP28 sockets for sale upon request.

I got my new DIP-28 Socket but the Flashcat USB software does not detect my AT27C512R chip. What do I need to do to get it to recognize it. Do I need to add new definitions? If I do how do I do that? Thanks!

Hi there, it's solved now I believe...

I submitted most of those AMD etc definitions via email a few months ago now... but not the Atmel list as it was pre-existing. Having a look through it the Atmel 512R isn't listed though and it does have different device IDs.

While looking through that list I also noticed that one of the existing chips ATMEL AT27C512 has a 16 bit programming definition?? Never come across this chip or that ID before so I can't verify it is correct or a mistake but doesn't seem to share a chip ID so probably fine to leave it as is..

However, for the newer 8 bit wide 28 pin 27C512R and the older 8 bit wide 27C512 the following definitions are needed, I have added it to my own build and tried it with the older 512 and I believe Dane has tried the newer 512R variety.
