is your chip is KM28C64A?KM28C64A is diffrent with KM28C64

you  try to  choice CAT28C64A  programming it .

My chip is a Samsung KM28C64A.
I tried CAT28C64A, log below:

   As an user.....Is your IC DIP or PLCC32 Package. If PLCC package, which adapter are you using? Please post a photo inserted the way you are using. Thank you

Hello,   
         Ensure that latest version of Xgpro is in use .

As i cant test this IC , do not have a sample ....
It seem, without any special order, you may have a faulty IC, a software bug, other hardware failure.
Hopefully ADMIN will help further with another tip, or correcting the problem :-(

回复 5# stevemas28C64 all is same.  but they have diffrent page size.
genuine product KM28C64A page size is 64.  KM28C64  page size is 32.  

AT28C64B(Non-Standard)  none page
AT28C64F   none page
you can test more with duffrect xx2864xx.

I don't understand your answer. I tried every 28C64 in the library - none work. You list the KM28C64A but this does not work either. I have tried 4 chips. All fail. I am not sure how you can say you support the KM28C64A if it fails. Have you tested your software with this chip or do you assume it should work? Perhaps I should return this programmer as it is useless for my operation.

    As an user....  Sometimes, when order new ICs, they are not new, some are sold defect, or are relabeled to look other reference.
The main result, most of times, if they are indeed close specifications, it is a different IDs problem that can be
easily ignored removing CHECK ID, but sometimes is something else.
What Admin ask you, if i understand well ( due to errors ) is if you have the opportunity to test with other
xx2864xx ICs , not the KM28C64A you have? ( i understand that you test four ICs with that reference, all gave same
error in result)
Are your ICs new? Recently ordered, or part of an old stock?
Have you an older programmer, to also test  there those KM28C64A you have?  ( as the ICs are a bit old)

I am sure, if there is a bug in the app for this IC, Admin will fix it soon for you, if time and patience is available, hopefully

I means, your chip may be IC relabeled . so hope test by others.
