Those 32bits really makes things easier!

The INL and DNL figures are not to great unfortunately, better then
nothing although..

Some years ago i debated with Eric about the STM v.s dsPIC, he showed the dsPIC
beat the STM on several factors. Still the STM32 timers are far
superior to the dsPIC.
But its going to be harder with the new F2 devices! :)

A STM32 in DIP or even SO would be a killer!

There one great thing with the DIP28 of the PIC's are PCB mountable
not requiring dual
layer boards and the ability to fit SMD between DIP legs, a big bonus
in some tight applications.

It seams the LPC device have some serious issues with that split'ed memory!?
