68B09 Datasheet, PDF – Alldatasheet
This two phase clock cycle is used as a full machine cycle in these processors. There were also variants such as the 68A09 E and 68B09 E ; the internal letter indicates the processor’s rated clock speed.
Williams Electronics was an especially prolific user of the processor, which was deployed in arcade hits such as DefenderJoustSinistarand Robotron: The design team believed that future system integrators would look to off-the-shelf code in ROMs to handle common tasks. Thursday, December 2, How do you know 68b09 datashert.
Along with theit was also one of the first microprocessors to implement a hardware multiplication instruction, and it features full bit arithmetic and an especially fast interrupt system. The CPU was also used in traffic signal controllers made in the s by several different manufacturers. In fallQualcomm and NXP announced that they would merge.

From Wikipedia, the free encyclopedia. These were primarily for the Japanese market, but some were exported to and sold in Australia. The Hitachi was an enhanced version of the with extra registers and additional instructions, including block move, additional multiply instructions and hardware-implemented division.
Williams also used the processor in many of its solid-state pinball machines; the CPU formed the core of the successful Williams Pinball Controller. With little to improve, the marks the end of the evolution of Motorola’s 8-bit processors; Motorola intended that future 8-bit products would be based on an 8-bit data bus version of the the The division changed its name to Freescale and has subsequently been acquired by NXP.
Among the systems to use the are the Dragon home computers, TRS Color Computerthe Vectrex home console, and early s arcade machines including DefenderRobotron: Like thethe included an undocumented address bus test instruction which came to be nicknamed Halt and Catch Fire HCF. Simple instructions could therefore execute in as little as two or three such cycles, although this also means that these cycles must be pretty slow.
The industry solved the problem of integrating code modules from multiple separate sources by using automatic relocating linkers and loaders—which is still the solution used today—instead of using relocatable ROM modules.

It was similar in dtaasheet to datasehet produced by, and several other suppliers.

Datsaheet index and stack registers allowed advanced addressing modes. As of spring the planned merger had yet to occur,  and in Julythe Chinese merger authority did not approve the acquisition before the deadline set by Qualcomm; it was effectively canceled on 26 July Like theit included an undocumented address bus test instruction that would exceed the limits of some memory controllers, evoking the nickname [.
Some instructions were replaced by more general ones which the assembler translated into equivalent operations and some were even replaced by addressing modes. Posted by Wywydyluva at 3: For yet another example, Motorola’s datashret programming manual  contains the full listing of assist09a so-called monitora miniature operating system intended to be burned in ROM. 86b09 a comparison, the higher resolution state machine of a CPU like the Z80 allowed clock frequencies times as high with the same datashfet memory chips, which was often the limiting factor.
This page was last edited on 17 Octoberat Neither Motorola nor Hitachi produce processors or derivatives anymore. In addition to home computers and game consoles, the was also used in a number of arcade games released during the early to mids.
Since a CPU designer could hardly guarantee where this code would be located in a future system, the design focused heavily on support ofcode that could be freely located anywhere in the memory map.
However, the decisions made by the design team made for a very powerful processor and made possible advanced operating systems like andwhich took advantage of the position-independent, re-entrant nature of the to create multi-user multitasking operating systems.
The latter used the E as their main CPU. It was a major advance over both its predecessor, theand the related. Among the significant enhancements introduced in the were the use of two 8-bit accumulators A and B, which could be combined into a single bit registerDtwo bit index registers X, Y and two bit stack pointers. A micro-controller version with a slightly modified instruction set, thewas discontinued as late as the second decade of the 21st century.
The very first Macintosh prototype, wire-wrapped by Burrell Smithcontained a Retrieved 2 April It was a major advance over both its predecessor, the Motorolaand the related MOS Technology TSC produced a Unix-like operating system uniFlex which ran only on such machines. The instruction set and register complement were highly orthogonalmaking the easier to program than the or This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1.
However, there is a certain amount of design philosophy similarity e.
