Software development company Microware developed the original OS-9 operating system not to be confused with the more recent Mac OS 9 for thelater porting it to the and i series of microprocessors. In order to speed time to market, common code modules would be purchased, rather than developed in-house, and integrated into systems with code from other manufacturers.
The index and stack registers allowed advanced addressing modes.
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. It was a major advance over both its predecessor, theand the related.
There the MB was dubbed the Peachprobably in ironic reference to the popularity of the. It was a major advance over both its predecessor, the Motorolaand the related MOS Technology There were also variants such as the 68A09 E and 68B09 E ; the internal letter indicates the processor’s rated clock speed.

The E was used in thethe3 and 4 computers as an optional alternative to their standardthethe -made home computers clones of the CoCoand the,etc. In fallDatasueet and NXP announced that they would merge. Thursday, December 2, How do you know 68b09 datasheet. Faster versions were produced later by Hitachi. 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.
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. Unlike contemporary processors that often used a microcoded architecture such as the and partly thethe ‘s internal design was more similar to early simple CPU designs and to some degree also 68bb09 RISC machines that appeared in the mid s and onwards.
Along with theit was also one of the first microprocessors to datasbeet a hardware multiplication instruction, and it features full bit arithmetic and an especially fast interrupt system. Retrieved 2 April However, there is a certain 68b009 of design philosophy similarity e.
The latter used the E as their main Dataeheet. It was similar in dztasheet to machines produced by, and several other suppliers. The division changed its name to Freescale and has subsequently been acquired by NXP. The CPU was also used in traffic signal controllers made in the s by several different manufacturers. Just like the andthe uses a two-phase clock to gate the latches. Views Read Edit View history.
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 Motorola-Freescale-NXP processors and microcontrollers.
Retrieved April 22, daatsheet The had an internal two-phase clock generator needing only an external crystal whereas the E needed an external clock generator. From Wikipedia, the free encyclopedia. Among the systems to use the are the Dragon home computers, TRS Color Computerthe Vectrex home console, and early s arcade machines including DefenderRobotron: A micro-controller version with a slightly modified instruction set, thewas discontinued as datawheet as the second decade of the 21st century.
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 Electronics was an especially prolific user of the processor, which was deployed in arcade hits such as DefenderJoustSinistarand Robotron: These were primarily for the 68h09 market, but some were exported to and sold in Australia. Retrieved from ” https: The design also focused on supporting reentrant code, code that can be called from various different programs concurrently without concern for coordination between them, or that can recursively call itself.
TSC produced a Unix-like operating system uniFlex which ran only on such machines.

This is because the Z80 combines two full but short clock cycles into a 86b09 long memory access period compared to the clock, while the more asynchronous instead has relatively short memory access times: However, the decisions made by the design team yielded a very powerful processor and made possible advanced operating systems like OS-9 and UniFlexwhich took advantage of the position-independence, re-entrancy orientated dztasheet of the to create multi-user multitasking operating systems.

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. 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.
Some opcodes also live on in the Freescale embedded processors. In addition to home computers and game consoles, the was also used in a number of arcade games released during the early to mids.
