plz tell me what is the best mcu?
Well Erik - now you understand my answer. I did notice who the OP was :)
This is just another trolling thread - meant to waste time on impossible goals.
We all know that the best uC is the one that is released two weaks after we must start shipping. It is half the price, half the energy and twice the processing power. However, it is still too expensive, to slow or to power-consuming for our next project, so we must once more dream about new chips that still hasn't been released.
