Oops sorry, yes I meant 'P ;-)

That's why :

It's a hobby/amateur project, so I use a prototype board to develop the
hardware, so I am limited to through-hole technology, meaning DIP
packages for everything. I don't have the soldering equipment for
surface mount components, and with my big fat fingers I probably
wouldn't be succesful with it anyhow ! ;-/
DIP packages also give me headaches, as I need a large (8 or 16 Mbits
serial data Flash memory), operatiung at 5 volts, and nothing is
available ! Grr...

Well Atmel lists them and Digikey sells them in tubes of 290 pieces, so
they are there !

Yeah, I hope production will rise so one can find them at Farnell or
RS, and preferably not in tubes of 290 pieces...
