Try the TI/Luminary parts. They use an ARM thumb-only core and come in
pretty small packages -- I'd be mildly surprised if they wouldn't run
off of an internal oscillator. TI probably indexes them under "ARM
Cortex" or something like that.

Ditto Microchip, and their PIC24 parts (which are really 32 bit
processors, AFAIK).

Yes, some (all?) of them have a (lousy) internal oscillator (+/-30%
accuracy for the LM3S8962) A lot of them _require_ external parts for
internal LDOs (maybe just a cap) and that sort of thing, some even
have/had an external (passive) RC filter for the PLL.

16-bit, actually.

I'd suggest looking at the Cortex M0 parts, as they are more aimed at
small systems. NXP has some with calibrated oscillator and no separate
core power supply. Cheap (< $2 in small quantities).

Hasn't NXP just announced a 8-pin Cortex-M0 part ? That's 32Bit with 6
GPIOs.

I presume you allow a decoupling capacitor ? ;)

If you are serious about 'battery' and don't want more parts, then
you'll need a wide-supply 32 bit core, and that suddenly shrinks the
field.

Energy Micro claim 1.8-3.8V Vcc range, in small packages.

NXP mention 1.8-3.6V on the LPC11xx

Nuvoton have some Cortex M0's in rollout, that claim 2.5-5.5V - nice
to have a low end 32 bit, that is PowerMOSFET compatible !!

Their tools/boards roadmap looks comprehensive, see

What the heck for? Setting aside why anyone in a sane state of mind
would use an entire micro controller just to blink an LED, when two
transistors and bit of chicken-feed would do the job with a good deal
less hassle: how could one ever, remotely, need a "more powerful" one?
