Manufacturing codes / identifiers on Freescale parts

     I have a DSC which has what I assume is a date code buried in with other letters / numbering, on the chip package. The part is an MC56F84789, the code is as follows:




So I'm assuming the 1243 will be week 43 of 2012. I'm sure I saw a document on Freescale's site which explained this numbering, but I can't find the document.


Also, do the MC56F84xxx series DSCs have a unique chip identifier? The closest I can find is the JTAG ID, in two parts. I was sure that this unique ID had the wafer position as well, but this may be for kinetis only.


Any information would be helpful,
