The production version is definitely 16K.

It's just that there's a few photos kicking about of a chip with a
serial number that if you look at the data sheet is 32K. Probably
from an earlier iteration *OR* from me reading the datasheet
wrong, maybe :)

I just worried for a bit that the devices Damien was testing with
were 32K not 16K. Since this is  all based on 16K that's really good
to know.

The specific numbers above I'll chew on.

Many thanks,


Michael.
