Motorola MC68000 ( Leadless chip carrier | CLCC package )

Motorola ceased production of the HMOS MC68000 and MC68008 in 1996, but its spin-off company, Freescale Semiconductor, is still producing the MC68HC000, MC68HC001, MC68EC000, and MC68SEC000, as well as the MC68302 and MC68306 microcontrollers and later versions of the DragonBall family.

Motorola ’ s next generation 32-bit microprocessor, the MC68000, led the wave of technologies that spurred the computing revolution in 1984, powering devices from Apple, Sun, and Hewlett Packard companies.

Its legacy product line was originally based on Motorola MC68000 processors, but then migrated to Intel i860 processors and finally Hewlett-Packard's PA-RISC architecture.

The Motorola MC68000 has a single unprivileged sensitive instruction:

Based on a newer, slightly more flexible, version of the Asters original Motorola MC6845 video chip, the Rockwell 6545, it worked by adding a new video mode, one with the ability to reprogram an extended, ( 2048 characters instead of 256 characters ) version of the character set, supported by an extended character memory of the video card that did not use one ( 8 bit ) byte per character, but an 11 bit " word ", so it could address each one of the available 2048 unique programmable characters.

Both the Dragon and the TRS-80 Color Computer are based on a Motorola data sheet design for the MC6883 SAM ( MMU ) chip for memory management and peripheral control.

The Motorola 88000 RISC chip was originally considered, but was not available in sufficient quantities.

It also was the first computer to ship with a general-purpose DSP chip ( Motorola 56001 ) on the mother board.

One of them was the HP Series 300 of Motorola 68000-based workstations, another Series 200 line of technical workstations based on a custom silicon on sapphire ( SOS ) chip design, the SOS based 16-bit HP 3000 classic series and finally the HP 9000 Series 500 minicomputers, based on their own ( 16 and 32-bit ) FOCUS microprocessor.

The Hitachi 6301 processor is an enhanced development based on the Motorola 6801 implemented in CMOS, with a number of extra instructions, various hardware system-on-single chip facilities on-chip, power management and support for a sleep state.

The A600 shipped with a Motorola 68000 CPU, running at 7. 09 MHz ( PAL ) or 7. 16 MHz ( NTSC ) and 1 MB " chip " RAM.

VGA is referred to as an " array " instead of an " adapter " because it was implemented from the start as a single chip ( an ASIC ), replacing the Motorola 6845 and dozens of discrete logic chips that covered the full-length ISA boards of the MDA, CGA, and EGA.

* Video: Motorola 6845, " CGA Plus " This chip was officially called the VGA ( Video Gate Array ).

Based on his participation in the basic circuit design, definition, and system design of the Motorola 6800 microprocessor and supporting computer chips, Mensch is a co-holder of several 6800 family patents, including the 6800 CPU, 6820 / 21 PIA, 6850 ACIA, and 6860 modem chip.

IBM, the third member of the AIM alliance, did design the chip together with Motorola in its Somerset design center, but chose not to manufacture it, because it did not see the need back then for the Vector Processing Unit.

* DSP: Motorola 56001 DSP chip at ( 16 MIPS ).

QDOS was implemented in Motorola 68000 assembly language, and on the QL, resided in 48 kB of ROM, consisting of either three 16 kB EPROM chips or one 32 kB and one 16 kB ROM chip.

These were all based on the Motorola 68000 chip.

Motorola tried to develop MIFARE-like chip for wired-logic version but finally gave up.

Despite the name, this chip was not part of the Motorola 680x0 series.

Traditional designs simply could not do this ; with so much of the chip surface dedicated to decoder logic, a true 32-bit design like the Motorola 68020 required newer fabs before becoming practical.

RISC II was also benched against the famous Motorola 68000, then considered to be the best commercial chip implementation, and outperformed it by 140 % to 420 %

By 1986 most large chip vendors followed, working on efforts like the Motorola 88000, Fairchild Clipper, AMD 29000 and the PowerPC.

Other ventures between Apple and IBM in this period included the Taligent operating system, and the PowerPC reference platform, a hardware chip alliance that included Motorola.

It was the first true " thirty-two bit bus / thirty-two bit instruction " chip from Motorola.

Also more traditional " von Neumann based " single chip microcontrollers may be regarded as competitors, such as the 6800 / 6809 based Motorola 68HC11, the Hitachi H8 family, and Z80-derivatives, such as Toshiba TLCS-870, to name just a few.

The Motorola floating point support package ( FPSP ) emulated these instructions in software under interrupt.

A large DIP package ( such as the DIP64 used for the Motorola 68000 CPU ) has long leads inside the package between pins and the die, making such a package unsuitable for high speed devices.

Some microprocessors, such as the Motorola 68000 and Zilog Z180, used lead counts as high as 64 ; this is typically the maximum number of leads for a DIP package.

Radio Service Software ( RSS ) is a software package used to program commercial Motorola two-way radios and cellular telephones.

The BridgeMaster II series followed, with a Motorola 68000 CPU and powerful software options like vector traces showing the trajectories of other ships as part of the ARPA package.
