Hi Ken,

you are correct, our APPS team is reading and posting to this forum. 
You mentioned:
 
* 8-10 address lines
* 4 chip selects
* what width of data bus would you expect?
* would this bus be a mux bus (not so much supported in ARM)?
assuming a mux bus and only 8-bit data / 8-bit address, 
* which 12 I/O would you like to be sacrificed for the bus interface?

Our "problem" is that we have too much functionality for the number 
of pins. Your request is, do not add pins but add functionality!
The more we multiplex functionality the more we get complaints along 
the lines "why did you combine feature A with B and not A with C. 

* What would be the use of such a bus? Memory mapped I/O? 

My guess is that a non-mux bus would be better suited but adds 
immediately 8 pins for the bus.

If we would offer a 80-pin or 100-pin device in TQFP or BGA would 
that be something?

Always open to constructive suggestions but I need to know details 
and what it would be used for, the applications. 

Thanks for expressing your desires here on this forum, we really try 
to use all the feedback from here to improve our products according 
to your, our customer needs.

btw, did you have a look at the LPC2138 / LPC2136? 

Cheers, Robert
