【文章內(nèi)容簡(jiǎn)介】 — transistor — — integrated circuit — — the circuit of large scale integration, a current chip finishes may intergrate millions pletely even go up must transistor, make puter volume less, function is stronger. , in the time of near 20 years, puter technology gets fast development, puter when industry and agriculture, research is educational, national defence and aerospace field have gotten extensive application, puter technology has been the important sign of a national modern level of science and technology.SingleChip Microputer birth in 20 century 70 decade, resemble the F8 single flat personal puter of Fairchid pany39。s Ramp。D. Socalled SingleChip Microputer is using the circuit technology of large scale integration handle central government unit ( Center Processing Unit, also CPU that claims frequently ) are with data memory ( RAM ) , program memory ( ROM ) and the other munication mouthes of I/O intergrate on a chip, form a minimum puter system, modern SingleChip Microputer has added suspension unit , the more plex more perfect circuits such as timing unit and the conversion of A/D, make the function 1of SingleChip Microputer more and more powerful, application is more extensive.20 century 70 decade, in microelectronics technology is being in development, stage and integrated circuit belong to , scale develops period, various new material new technologies have not ripened , SingleChip Microputer is still in elementary development, stage and element integrated scale still have less parison, as function has more simple parison, CPU and RAM are some on have still included some simple mouthes of I/O to intergrate go to chip, elephant Farichild pany belongs to this type , it need to still match other peripheral handlings, circuit forms plete calculation just now system. Similar SingleChip Microputer still has the Z80 tiny processor of Zilog pany. In 1976, INTEL pany has put out MCS48 single flat machine, the SingleChip Microputer of this period is just 8 genuine single flat personal puters , and pushes to market. It with volume is little, function is whole, price lows have won extensive application, have established foundation , bee the important milestone on SingleChip Microputer development history for the development of single flat machine.In MCS48 lead , its rear each most conductor pany develops and develops own SingleChip Microputer in succession , resembles the Z8 series of Zilog pany. Have been beginning of 80 decade, SingleChip Microputer has developed high performance stage, the MCS51 series Motorola pany39。s 6801 of elephant INTEL pany is with 6802 serieses, 6502 serieses of etc. and the 6501 of Rokwell pany, besides, HITACHI and famous electrical pany39。s NEC of Japan have developed in succession the SingleChip Microputer special that has own characteristic.80 decade, world is each big the SingleChip Microputer that pany develops product kind muti_function winner eagerly, have the tens of series kinds more than threehundreds approximately, right now SingleChip Microputer belongs to genuine single flat to melt, have intergrated CPU, RAM, ROM and number numerous I/O mostly interface and various suspension system, the SingleChip Microputer and function that even still has some tape converters of A/D are more and more powerful, the capacity of RAM and ROM also more and more big, seek address space may even reach 64kB, in other words, SingleChip Microputer development has gone to a brandnew stage, application field is more extensive, a lot electric home appliances move towards the intelligent development road that uses SingleChip Microputer control.After 1982, 16 single flat machines e out , represent that MCS96 whose product is INTEL pany is series, 16 single flat machines have increased one time pared with 8 machines and data widthes, the ability of real time of handling is stronger, main and frequently higher, integrated degree has reached one hundred and twenty thousands transistors, RAM increases , have gone to 232 bytes, ROM has reached 8kB , and has 8 A/Ds that suspend source and have at the same time deploied multichannel to change passageway , I/O of high speed handles unit , applies to more plex control system.90 decade afterwards, SingleChip Microputer has gotten fast development, world each most conductor pany has developed the SingleChip Microputer with more powerful function in succession. American Microchip pany has issued a kind of new generation PIC series SingleChip Microputer of plete not patible MCS51 , has aroused the extensive solicitude of business circle, its special product has only Sub_clause of 33 to retrench instruction fair , have attracted a lot of users, make people concentrate from the 111 plex instruction of INTEL to walk out of. PIC SingleChip Microputer has gotten fast development, in business circle, possess position.Soon afterwards matter, the personage of familiar SingleChip Microputer is more clear , more single flat machines e in great numbers , MOTOROLA pany has issued MC68HC series SingleChip Microputer in succession, some famous panies of Japan has developed the product of stronger performance , but the SingleChip Microputer of Japan is controled normally used in the system special, and not resemble the panies such as INTEL to put in to market form general single flat machine. Such as the uCOM87 series SingleChip
