    \$\begingroup\$ This must all be in a datasheet somewhere. Read between the lines (i.e. carefully), manufacturers do not arbitrarily make up new part numbers unless there are actual part differences. \$\endgroup\$ – Adam Lawrence May 21 '13 at 16:01

Look at Freescale's comparison page. I believe all of the models you listed are in the table. They vary by cpu/bus clock speeds and min/max operating temperatures.
