Motorola 68EC000 controller The 68EC000 is a low-cost version of the 68000 with a slightly different pinout, designed for embedded controller applications. The 68EC000 can have either a 8-bit or 16-bit data bus , switchable at reset.
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 Freescale 683xx (formerly Motorola 683xx) is a family of compatible microcontrollers by Freescale that use a Motorola 68000-based CPU core. The family was designed using a hardware description language , making the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.
The following is a partial list of NXP and Freescale Semiconductor products, including products formerly manufactured by Motorola until 2004. NXP and Freescale merged in 2015. NXP and Freescale merged in 2015.
The Motorola MC68010 and Motorola MC68012 are 16/32-bit microprocessors from Motorola, released in 1982 as successors to the Motorola 68000. [3] The 68010 and 68012 added virtualization features, optimized loops and fixed several small flaws to the 68000.
Motorola never produced a 68050. [4] For example, the Motorola 68010 (and the obscure 68012) is a 68000 with improvements to the loop instruction and the ability to suspend then continue an instruction in the event of a page fault, enabling the use of virtual memory with the appropriate MMU hardware. There were, however, no major overhauls of ...
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.
At the time the Motorola 68000 was designed, Motorola's design and fabrication services were outdated. Although even small companies like MOS Technology and Zilog had moved on to silicon gate depletion mode NMOS logic on ever-larger wafers, Motorola was still using metal gates and enhancement mode and their largest fab worked on 4-inch wafers long after most lines had moved to 5-inch.
