I've recently attended Design With Freescale to learn from Mr. Beeker's presentation on PCB design and EMI considerations. The take-away is that the most important factor in board design is knowing the switching time of the parts.
Which parameter on which datasheet am I looking for to find this number? I'm expecting it to be a value in nS.
Is this time the same between all M0 parts?
To be clear I'm not looking for the MCU core frequency. I am looking for the transistor switching time for use in the EMI design domain.
