The 48 bytes of sram are enough to encode several state machines. It has pwm and dedicated IR signalling output, but no ADC for input.

It's generally designed to be a very simple controller-of-things. Push an up button, increase the pwm output up to some limit, etc. remote controls, fans, etc.,

Indeed. I've seen a retail toy use a similar microcontroller from Nyquest to accept infrared control commands and drive some H-bridge drivers to make a simple, cheap RC car.
