'[EE]:Looking for uC suggestions'

I know I could do this with a PIC but there's probably a better
solution.
I'm looking for uC available in QFP or similarly small flat package
with some onboard ROM (OTP/Flash) and a non-multiplexed external bus.
The only other requirement is a uart and I2C or SPI. Cost matters.
Qty in hundreds.

I seem to be thinking Japanese like H8/300, M16. Any others from the
collective wisdom ?

Oh - One other requirement - Not on allocation !!

Steve.

This may be too expensive and I have not used it yet, but how about
http://www.rabbitsemiconductor.com

It's about $11(USD) in 100's.

It is a bit too much. I looked at it but the local guy wanted US$20
with a MOQ of 100. Nothing like a little bit of markup.

I did forget to mention that. It's for data. Just a large blob of RAM
that I want to shuffle data around in fairly quickly.
Most micro external busses are mux'd and I'd like to avoid the space
of the latch & decoding logic.
A QFP uC and TSSOP ram is about the smallest footprint I can think
of to get 32k+ of ram to play in.
