If you ARE refering to CPU then i have no lcue as to what you are talking about. But I do know that SCSI Ultra320 uses a 68-Pin interface and SCSI is for harddrives and ROM's and such. And 80 pin is either for SCSI Ultra320 aswell as E-IDE Harddrives and ROM's. If you are refering to E-IDE, which I think you are not it is the latest tech for E-IDE I think. but for SCSI I would take a guess as I have no clue that the more pins the better. Maybe you can search differenly now to get better results.
Oh roflmao I see. Your looking at a lcd control panel/chip. Yikes good luck. Your only source will likely be Samsung themselves ask for the whitepapers. It will show how its driver IC is used etc. Look in whitepapers, at applications section. (samsung is one of the big 3 lcd manufacturers)
