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

29 | The Freescale (was then Motorola) CPU32 is a CPU core that is | ||
30 | based on the 68020 processor. For the most part it is used in | ||

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