The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel 's x86 microprocessors.
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") [2] [3] is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal ...
The jump from the 68000/68010 to the 68020/68030, however, represents a major overhaul, with innumerable individual changes. By the time the 68060 was in production, Motorola had abandoned development of the 68000 family in favor of the PowerPC. The 68060 is the last 68000 family processor from Motorola.
The price of a single MC6800 microprocessor was $175. Link Young was the product marketer that developed the total system approach for the M6800 family release. In addition to releasing a full set of support chips with the 6800 microprocessor, Motorola offered a software and hardware development system.
The NXP ColdFire is a microprocessor that derives from the Motorola 68000 family architecture, manufactured for embedded systems development by NXP Semiconductors. It was formerly manufactured by Freescale Semiconductor (formerly the semiconductor division of Motorola ) which merged with NXP in 2015.
In 1981 a 6809 in single-unit quantities was $37 compared to $9 for a Zilog Z80 and $6 for a 6502. [1] It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature competitive with newer designs and not price ...
Atari Games used the 68010 in some of their arcade boards such as the Atari System 1. Some owners of Amiga and Atari ST computers and Sega Genesis game consoles replaced their system's 68000 CPU with a 68010 to gain a small speed boost. [7] In practice, the overall speed gain over a 68000 at the same frequency is less than 10%. Motorola 68451 MMU
The 6501/6502 introduction in print and at Wescon was an enormous success. The downside was that the extensive press coverage got Motorola's attention. In October 1975, Motorola reduced the price of a single 6800 microprocessor from $175 to $69. The $300 system design kit was reduced to $150 and it now came with a printed circuit board. [60]
