i have been using an early version for over a year and have been very impressed with the processing power. 20-25MIPS.

the cygnal micros have on chip oscillator for upto 15MHz operation and on board reset circuitry. These help to reduce external circuitry to allow an almost single chip product. The i/o pins are also 5v tolerant. THe Programmable Counter array is a very useful feature for multiple output PWM applications.
