The LPC2468/LPC2478 chips are the best I could find in today's market in
terms of price/performance&peripherals ratio (and no, this is not
advertising, just my own thoughts). It comes at a price though: they're
very large (LQFP208 or BGA) thus it's quite hard to prototype with them,
or even design a PCB.
Also, the STR912 chips from ST are quite interesting (ARM9@96MHz with
512k/96k internal memory, external interface and a lot of peripherals).
STM32 has at least one quirk: you can't use the USB and CAN ports at
the same time, which doesn't work for me.
And they also don't have Ethernet :( I'd really, really like to have a
chip that is either a LM3S (Luminary) with external memory interface, or
a STM32 (ST) with Ethernet :) There are rumors that Luminary is
preparing some chips with external memory interface, so the future might
look bright after all :)
