Require programming specification for EPM5064li

Hello John

We dont have an NDA with Intel for this or any other Intel product, the programmer we purchased mentioned that it could program this IC, but when we went to use it, we noted a restriction to the later 0.65 micron version of the IC and would not cover the earlier 0.8 micron version which is what the design of the PCB calls out for.

I dont know what the major difference is between the 2 versions, but I do know when we insert the earlier version into the programmer, it does not allow any reading or recognition of the blank chip .

How can we proceed?

Cheers,

Paul
