If I'm correct in my understanding the chip on the right would have a manufacturing date of year 1998 week 06, correct?

What about the chip on the left. Confused

Can I assume this date code interpretation comes from some widely-known page in an Intel DATA BOOK that there's a scan of somewhere...? Because anything else is just speculation and hearsay, as we saw with the 1101 batch codes in an earlier thread.

Actually it comes from Intel Smile
A79734 shoul be made in week 34 of 97

Some Intel chips use CCYYWW (seen it on Xeons etc)

Thank you for this information.

It's CYYWW in my mind before. Smile

Again, let's see it in print. Post a link to an official Intel source, scan of a data book page, etc. Wink

This is the only Intel info I have on FPO's. Might be useful for some.. it does not explain the extended date code above.

Same info on their i960 page as well
http://www.intel.com/design/support/faq/i960_processors/i960_general.htm

and mentioned in many of their datasheets

for example

None of which really explains the discrepancy Tim pointed out. I can't seem to find it explicitly documented anywhere that some FPOs use two digits for the year. Or is that just a reasoned assumption?

Indeed - and my assumption is, if it's true it's gotta be published somewhere. Wink

Leave it to Intel to be the oddball with date codes...

Another possibility is the format is correct, but the first work week digit implies something else or has a double meaning. We know there can be some weeks between the various stages a chip is passed through until completed.

More speculation. Smile

BTW, what plant corresponds to plant code "C"?
