I-FT232RL yi-chip yokuguqula i-chip enokuguqula phakathi kwe-USB kunye ne-serial Ports kwaye isetyenziswa ngokubanzi kwiibhodi zophuhliso lweekhompyuter, ezifana ne-microtrolings zophuhliso malunga ne-FT232rl, kubandakanyaImbali yophuhliso, isakhiwo, imigaqo-siseko kunye nesicelo, kwaye sinamathela kumzobo wepakeji.

Ft232rl yi-USB kwi-serial chip chip eveliswe yiNkampani yaseBritani ye-FTDI.Inkampani yasekwa ngonyaka ka-1990 kwaye ekuqaleni igxile kuphando kunye nophuhliso lweebhokisi eziphezulu zeTV.Ngokukwenyani kweekhompyuter kunye nophuhliso olukhawulezileyo lwetekhnoloji yenethiwekhi, i-ftdi yaqala ukuguqula kwaye itshintshe igxile kwi-R & D kunye nemveliso ye-USB Chips.Ngo-1999, i-ftdi ivelise i-USB-to-i-chip chip ft8U232am, eye yaba yenye yeetshipsi ze-USB ze-USB kwintengiso ngelo xesha.Ngotshintsho oluqhubekayo kwimfuno yentengiso kunye nenkqubela phambili eqhubekayo yetekhnoloji, i-ftdi isungule ngokulandelelana kwe-USB kwi-chips ye-porlial port chips, eyaziwa kakhulu yi-ft232rl.

I-FT232RL yeza ngo-2003. Njengesizukulwana sesibini se-USB ukuya kwi-chip ye-ftdi, inesantya esiphezulu sokuhambisa idatha, ukusetyenziswa kwamandla okuphakathi kunye nokunxibelelana komsebenzi ngakumbi kune-chip yokuqala yesizukulwana.Ngokukhawuleza yaba enye yezona zinto zithandwayo ze-USB kwiitshipsi ze-serial kwintengiso.Ukuze ufezekise imfuno yokutshintsha kweNtengiso, i-FTDI iphinde yasungula uthotho lwe-USB enamandla kakhulu kwi-chips ye-serial port chips esekwe kwi-chip232rl chip, efana ne-ft223h, ft232h, pht.

Itekhnoloji ye-USB iyaqhubeka ukuqhubela phambili, ibango le-USB kwii-chips ze-porrial e-serial ikhula nayo.Ukujonga kwikamva, i-ftdi iya kuqhubeka nokuphuhlisa i-USB-to-chipsial chips ye-sesb ukuya kufezekisa iimfuno zemeko eyahlukeneyo yesicelo.Kwangelo xesha, i-ftdi iya kuhlala iqhubeka nendlela yophuhliso yetekhnoloji ye-USB kwaye iphuhlise ngakumbi i-USB chips entsha yokwandisa kwakhona ukugubungela.

I-FT232RL yi-chip yokuguqula i-chip enokuthi iguqule i-USB ukuya kwi-Isb ukuya kwi-Iart yoMngcipheko we-Iars kwaye unokuguqula kwimodi ye-actchronous okanye i-asynchronous bit-bang.I-chip ixhotywe ngemveliso ye-gene ye-geneck ye-geneck, kunye ne-New FDDICIP ye-ID ye-Dongle.Ukongeza, i-chip ikwabonelela ngokukhetha i-asynchronous ye-asynchronous kunye ne-synchronous bit, ekomelezeni ukuguquguquka kwalo.Kwimilo ye-USB-to-to-i-serial ye-i-US, i-FT232RL ilula kakhulu inkqubo yoyilo ngokudibanisa ngokupheleleyo i-EOPROM yangaphandle, ukuseka i-Clock, kunye nabaphathi be-USB kwisixhobo.I-chip ineekhonkwane ezingama-28 kwaye yamkela ukupakisha i-SSOP ukulungiselela ukudityaniswa kweziphaluka ezahlukeneyo.Uluhlu lobushushu olusebenzayo luyi-40 ° C ukuya kwi + 85 ° C kunye ne-voltage yombane yi-3.3v kwi-5.25v, eqinisekisa ukusebenza kwayo kwizinto ezahlukeneyo.

I-FT232rl iqulethe ezi zinto zilandelayo.

I-FT232RL ineesekethe ezithile ze-Loogic zangaphakathi zokuhamba kwedatha, ukulungisa idatha, ukuguqulwa kweProtocol kunye neminye imisebenzi phakathi kwe-USB kunye ne-UCT umfanekiso we-USB kunye ne-UCRT.Ezi sekethe zeNgxelo zihlala zimiliselwa yi-microcontrollrolletroller okanye izixhobo ezinikezelweyo.

I-FT232RL ikwanayo nememori ye-EEPROM yokugcina inkcazo yesixhobo, ulwazi lomenzi, ulwazi lwemveliso kunye neeparamitha ezithile zoqwalaselo.Olu lwazi lunokufundwa yikhompyuter okanye kwesinye isixhobo kwaye isetyenziselwe ukuchongwa kwesixhobo kunye noqwalaselo.

Imbonakalo ye-UART yenye yemisebenzi ephambili ye-FT232rl, ebonelela ngamandla e-serial yonxibelelwano.I-UCREARCH ye-UART ibandakanya igalelo ledatha ye-Irial kunye nezikhonkwane zexabiso, i-Baud Ixabiso lesekethe, i-Buffer yedatha, njl njl.

Ukuqinisekisa ukusebenza okuzinzileyo kwe-FT232rl, umthengisi we-Clock Stoner kunye nemodyuli yolawulo lwamandla zadityaniswa ngaphakathi.I-generator yomqondiso we-Clock inoxanduva lokubonelela ngemiqondiso efunekayo kwiimodyuli ezahlukeneyo ngaphakathi kwe-chip ukuqinisekisa ukuba banokusebenza kunye.Imodyuli yolawulo lwamandla inoxanduva lokulawula nokulawula ukuhanjiswa kwamandla kwi-CHIP ukuqinisekisa ukuba i-chip isebenza ngaphakathi kwevolthi efanelekileyo kunye nodidi lwangoku.

Isinxibelelanisi se-USBUnxibelelwano luqukethe imigca yedatha ye-USB, uLawulo lwe-USB ulawulo lwe-Logic kunye nesekethe enxulumene nokuchongwa kwesixhobo se-USB.Isinxibelelanisi se-USB sinokufumana idatha ye-USB evela kwikhompyuter kwaye idlulise idatha kwicandelo lokulungisa ngaphakathi kwi-chip.Kwangelo xesha, inokudlulisela idatha eyenziwe ngaphakathi kwi-chip ibuyele kwikhompyuter ngexesha lokufezekisa unxibelelwano lweendlela ezimbini.

Umgaqo wokuSebenza we-FT232rl unokwahlulahlulwahlulwa ngala manyathelo alandelayo.Okokuqala lunxibelelwano lwe-USB.Xa i-ft232rl ifakwe kwi-USB yezibuko lekhompyuter, iya kuqala unxibelelwano lwe-USB kunye nekhompyuter.Ngeli xesha, ikhompyuter iyakuqonda i-FT232rl njengesixhobo esisebenzayo se-USB kwaye sinike idilesi eyahlukileyo.Oku kulandelwa kwangoko nguShawule weDatha ye-USB.Nje ukuba ukuqaliswa kugqityiwe, idatha inokudluliselwa phakathi kwe-FT232rl kunye nekhompyuter kwi-USB ixpression.Xa ikhompyuter kufuneka ithumele idatha kwi-FT232rl, idatha idluliselwa kwi-chip ngaphakathi kumgca we-USB.Ngokufanayo, xa i-ft232RL kufuneka ithumele idatha kwikhompyuter, iya kuthumela idatha ngomnxeba we-USB.Oku kulandelwa luguqulo lwedatha ye-serial.I-FT232RL inonxibelelwano oluhlanganisiweyo lwe-URT, olwenzileyo lokuguqula idatha ehambelana nayo idluliselwe kwidatha ye-USB kwidatha ye-serial, okanye ukuguqula idatha ye-serial ibuyise idatha yedatha.Ngale ndlela, ft232rl iqonda ukuba ifomati yefomati yedatha phakathi kwe-USB kunye ne-Special.Emva koko kuza unxibelelwano lweseti.Ngomnxibelelaniso we-FT232rl, abasebenzisi banokudibanisa ngokulula izixhobo zangaphandle ze-serial, ezinjenge-microcontrontrolletroller okanye ezinye izixhobo ezinomsebenzi wonxibelelwano lwe-serial.I-FT232rl inokuthumela idatha efunyenweyo kwezi zixhobo zangaphandle nge-special, kwaye kwangaxeshanye, inokufumana kwakhona idatha ethumela i-serial thumela ikhompyuter i-computer inxibelelanise kwikhompyuter.Okokugqibela, kukho inkxaso yomqhubi.Ukuqinisekisa ukuba ikhompyuter ikwazi ukubona okanye inxibelelane ne-FT232rl, umsebenzisi kufuneka afake abaqhubi abatshatileyo.Aba baqhubi babonelela ngeprotocol eyimfuneko kunye nenkxaso yenkqubo yokunxibelelana phakathi kwenkqubo yokusebenza kwekhompyuter kunye ne-FT232rl.Ngokufaka abaqhubi, ikhompyuter iya kuba nakho ukuqonda nokulawula i-FT232rl ukuze isebenze ngokufanelekileyo.
