This family of chips built upon the 68h series of chips, which were their forebears.

1 The 68k family

• Generation one
  • Motorola 68000 a hybrid 16/32 bit chip
  • Motorola 68EC000
  • Motorola 68HC000
  • Motorola 68008 a hybrid 8/16/32 bit chip
  • Motorola 68010
  • Motorola 68012
• Generation two (fully 32-bit)
  • Motorola 68020
  • Motorola 68EC020
  • Motorola 68030
  • Motorola 68EC030The 68EC030 is a microprocessor from Motorola. It is a lower cost version of the Motorola 68030, the difference between the two being that the 68EC030 does not have an on-chip memory management unit. The 68EC030 was used as the CPU of one model of the Ami
• Generation three (fully 32-bit)
  • Motorola 68040The Motorola 68040 is a microprocessor from Motorola. It is the successor to the Motorola 68030 and is followed by the Motorola 68060 (the 68050 was an abandoned project and never shipped, the 050 was to the 040 what the 030 was to the 020, a simple die s
  • Motorola 68EC040The 68EC040 is a version of the Motorola 68040 microprocessor intended for e''mbedded c''ontrollers. It differs from the 68040 in that it has no FPU or MMU. This makes it less expensive and draw less power. Note In keeping with general Motorola naming, th
  • Motorola 68LC040The 68LC040 is a l ow c ost version of the Motorola 68040 microprocessor with no FPU. This makes it less expensive and draw less power. Although the CPU now fits into a feature chart more like the Motorola 68020, it continues to include the 040's caches a
• Generation four (fully 32-bit)
  • Motorola 68060The Motorola 68060 is a 32-bit microprocessor from Motorola, and is the successor to the Motorola 68040. The 68060 is the highest performance 680x0 family processor available. The 68060 is not just a redesign of the 68040, but a from-scratch entirely new
• Others
  • Motorola CPU32The Motorola 683XX aka CPU32 is a family of compatible microcontrollers that use a Motorola 68000 CPU core. The family was designed using software that compiles a computer language into hardware. The submodules of the microcontroller were designed indepen (aka Motorola 68330)
  • Motorola ColdfireThe Motorola Coldfire is a 68k architecture microprocessor manufactured for embedded systems development by Motorola (now Freescale Semiconductor). 68k microprocessors Motorola 68090.
  • Motorola Dragonball

2 The architectural heritage

People who are familiar with the PDP-11 or VAX usually feel comfortable with the 68000. With the exception of the split of general purpose registers into specialized data and address registers, the 68000 architecture is in many ways a 32-bit PDP-11.
