The LPC800 series from NXP is a sweet little Cortex-M0+ MCU family that's available in 20, 16, and even 8-pin (DIP) packages. It's a shame the 8-pin isn't available in an SMD form factor, but hey - it's still a 32-bit MCU in 8 pins.
We'll just have to keep this sucker in mind for future projects. :-)
