Went to TI's MSP430 'seminar' today. The series has some interesting features. Taking a close look at the data sheet here are some specs: Supply voltage: min = 1.8, max 3.6 Max frequency = 8MHz at 3.6V, linearly derated down to 4.15MHz at 1.8V Now, the way I see it, the only way to run this chip at 8MHz and be within spec is to have a perfect 3.6V +/- 0V power supply. Stupid! On other topic: One interesting spec they pointed out: the input leakage current on the MSP430 is max 50 nanoamp, They mentioned that this is much better then their competition. (for example, PIC16F819 is 1 microamp). It is rather difficult to see how you can create anything useful out of an PIC16F819 that doesn't draw more current in leakage than chip Idd.
