I agree that it is not 100% unambiguous. However, in your case I interpret the
info as:
'xxx' is 'B' (no significance?)
Type is LPC2106 (not LPC2106/00 or LPC2106/01)
Year of manufacture is 2004.
However, the second digit of your week code and the revision code seem to be
missing. Are you sure there aren't any other characters after TRL041? On
one of my chips this is carried onto another line as there is not enough space
to fit 'TPG0444C' on one line on the chip.
However, they do not appear to be consistent with leading zeros. I have another
with 'TP411C'. As it can't be week one 2041 I assume it is week
11, 2004.
Maybe your sample is week 1, 2004 but that still doesn't explain the
missing revision code. Post-christmas hangovers perhaps? ;-)
Thanks.
However, the marking is
LPC2106B
CC8310
TRL041
as three lines of text, on the chip-top.
Because the first line has no xxx suffix, and the others don't seem to
match, I wonder if this chip pre-dates the establishment of the numbering system
described in the errata.

The errata sheets for the LPC2106 explain how to interpret the device
