Lpc2000

Hello David,

as my focus is the LPC2000 family, the LPC2114 would be closest to
what you are looking for. The number of AD-inputs  come in a little
short  of your requested 8 (there are 4) but everything else would be
a nice fit and with a 64-pin package you hopefully get enough I/O. 
The same device is also available as external bus version in a 144-pin
package where you actually get 8 analog inputs and you can use the
external bus (or parts of it)  as digital I/O.

Cheers, Bob
