I don't think that is the whole story.  The 400mSec for the LPC is due to a
voltage convertor starting up inside the chip, as I recall.  It is not a
function of flash memory speed.  Perhaps the SAM part keeps a voltage
convertor running all the time inside.  I do not know.  But I use IAP in my
designs with the LPC.  Works great.
