It'll be lower down on the chip, likely just to the right of the 4-digit
manufacture date code.  TGJ1 is the physical package type.

For example:

88W8686-NAP1
KHC5811.4
0644 B2P ES
TW

The "B2P" is the revision, so for example I've got a B2 8686.  The 8385
revision code should be in the same place.

http://www.zcom.com.tw/program/big_pic/XG-880M.jpg

That picture shows a B2 revision ("B2P").
