The Freescale (was Motorola) 68000 CPU is the first generation of
the well known M68K family of processors. The CPU core as well as
being available as a stand alone CPU was also used in many
System-On-Chip devices (eg 68328, 68302, etc). It does not contain
a paging MMU.

bool
help
The Freescale (was then Motorola) CPU32 is a CPU core that is
based on the 68020 processor. For the most part it is used in
System-On-Chip parts, and does not contain a paging MMU.

The Freescale ColdFire family of processors is a modern derivitive
of the 68000 processor family. They are mainly targeted at embedded
applications, and are all System-On-Chip (SOC) devices, as opposed
to stand alone CPUs. They implement a subset of the original 68000
processor instruction set.
