New ContributorWhere or how to program EPM7064LI44

Excellent. I will look to source the chips today. I thought I found some when I googled the other day. But that doesn’t mean they actually have them. I’ll go ahead and get the programmer as well. I believe you are correct about it being written in AHDL. Seems like I saw that on one of the documents somewhere. There is some confusion on which exact device I have. In the parts list for the unit, P/N EPM7064LI44 is called out. In the documents called “Firmware Code” it says the device is a EPM7064LC44. Is there any difference between the LI and LC that would be a concern? I didn’t see any markings on the device itself to determine which one of the two is actually installed.
Also. Is EPM7064LI44-xx (-7, -10, -15…) how the speed is determined. Does the final –xx designate the speed?
It would be nice to convert to a current production device. I am going to try the other route first but this is definitely an option worth noting. I may look into this option as a long term solution in the future and hope to find some EPM7064LI44s for now.
New ContributorI was able to confirm the device in the unit is an EPM7064LI44-15. Peeled back the sticker affixed to it and saw the actual Altera P/N. From my research online, the only difference between the 7064LI and 7064LC is Operating Temperatures and Voltage Supply with the LI having the greater Operating Temperature and Voltage Supply window. So I am trying to find some EPM7064LI44-15's now. Unless you respond and say trying to go with the current production device is my best option.
