I-FT232RL iyi-chip yokuguqula i-interface engaguqula phakathi kwamachweba e-USB nama-serial futhi isetshenziswa kabanzi emabhodini okuxhumana ama-computer of computer okuphathelene nama-computer akhona, amaphrinta, le ndatshana izokunikeza imininingwane enemininingwane nge-FT232RL, kufaka phakathiUmlando wayo wokuthuthuka, isakhiwo, umgomo wokusebenza kanye nesicelo, futhi unamathisela umdwebo wokufaka.
Namabhuku
FT232RL yi-USB ku-serial port chip ekhiqizwe yinkampani yaseBrithani FTDI.Le nkampani yasungulwa ngo-1990 futhi ekuqaleni igxile ocwaningweni nasekuthuthukisweni kwamabhokisi aphezulu we-TV.Ngokuthandwa kwamakhompiyutha kanye nokuthuthukiswa okusheshayo kwe-Network Technology, i-FTDI yaqala ukuguqula futhi yasusela ukugxila kwebhizinisi kwayo ku-R & D kanye nokukhiqizwa kwama-chip we-USB I-Chips.Ngo-1999, i-FTDI yakhiqiza i-USB ye-USB-to-to-serial ft8u23222, eyaba ngenye yama-chips asekuqaleni athunyelwa emakethe ngaleso sikhathi.Ngoshintsho oluqhubekayo ekufuneni kwemakethe kanye nentuthuko eqhubekayo yezobuchwepheshe, i-FTDI yethule ngempumelelo ama-USB ahlukahlukene kuma-chip e-serial port, owaziwa kakhulu yiwona we-FT232RL.
I-FT232RL iphume ngo-2003. Njengoba isizukulwane sesibili se-USB siye kwi-serial chip eyethulwe yi-FTDI, inesivinini sokudluliswa kwamanani aphezulu, ukusetshenziswa kwamandla okuphansi kanye nokusetshenziswa kokunwebeka okwengeziwe kwe-chip yokuqala.Ngokushesha kwaba ngomunye we-USB ethandwa kakhulu kuma-serial chips emakethe.Ukuze uhlangabezane nesidingo esiguqukayo semakethe, i-FTDI sekwethule uchungechunge lwe-USB enamandla ngokwengeziwe kuma-serial port chips asuselwa ku-FT232RL Chip, njenge-FT2232H, FT232H, njll.
Njengoba ubuchwepheshe be-USB buqhubeka buqhubekisa phambili, isidingo se-USB kuma-serial port chips nawo akhula.Uma ubheka ikusasa, i-FTDI izoqhubeka nokuthuthukisa ama-chips athuthukile we-USB-to-to-serial ukuze ahlangabezane nezidingo zezimo ezihlukile zohlelo lokusebenza.Ngasikhathi sinye, i-FTDI izophinde futhi iqhubeke nomkhuba wentuthuko wobuchwepheshe be-USB futhi uthuthukise ama-chips amasha e-USB ukuze aqhubeke anwebe ukumbozwa kwawo kwemakethe.
I-FT232RL iyi-chip yokuguqulwa kwe-interface engaguqula i-USB ibe isikhombimsebenzisi se-serial uart futhi ingaguqula imodi yokuvumelanisa noma ye-asynchronous Bit-Bang.I-Chip ifakwe umphumela wokuzikhethela wewashi lewashi, kanye nesici esisha se-FTDICHIP-ID yezokuphepha dongle.Ngaphezu kwalokho, i-chip ibuye ihlinzeke ngezindlela zokuzikhethela ze-asynchronous ne-bangEmiklamweni ye-USB-to-serial, i-FT232RL yenza lula inqubo yokwakhiwa ngokuhlanganisa ngokuphelele i-EEPROM yangaphandle, ukujikeleza kwewashi, kanye naku-USBI-chip inezikhonkwane ezingama-28 futhi yamukele ukupakishwa kwe-SSOP ukwenza lula ukuhlanganiswa kwizibuyiseke ezahlukahlukene.Uhla lwayo lokushisa olusebenzayo lungu-40 ° C kuya ku-85 ° C kanye ne-Power Supply Voltage yi-3.3V ku-5.25V, eqinisekisa ukusebenza kwayo ezinzile ezindaweni ezahlukahlukene.
Ezinye izindlela nokulingana
I-FT232RL iqukethe izinto ezilandelayo.
Umjikelezo we-logic wangaphakathi
I-FT232RL iqukethe amasekethe athile anengqondo okulawula ukuhamba kwedatha, ukucubungula idatha, ukuguqulwa kwe-protocol neminye imisebenzi phakathi kwesibonisi se-USB nesibonisi se-UART.Le mibuthako ye-Logic ivame ukwenziwa kwenziwa ngama-microcontroller noma i-Hardware ezinikezele.
Imemori ye-EEPROM
I-FT232RL ibuye iqukethe imemori ye-EEPROM yokugcina izincazelo zedivayisi, imininingwane yomenzi, imininingwane yomkhiqizo kanye namapharamitha wokucushwa.Lolu lwazi lungafundwa yikhompyutha noma olunye idivaysi futhi lusetshenziselwa ukukhonjwa kwensiza nokucushwa.
Isikhombimsebenzisi
I-Uarc interface ingenye yemisebenzi esemqoka ye-FT232RL, enikeza amandla okuxhumana nge-serial.I-Interface ye-UART ifaka okokufaka kwedatha ye-serial kanye nokukhipha, isivinini sokulawula isilinganiso, njll. Imininingwane ye-serial iyaxhumana namadivayisi we-serial angaphandle ngokuxhumeka kwe-UART, njengama-mictocontroller, izinzwa, njll.
I-Clock and Power Management module
Ukuze uqinisekise ukusebenza okuzinzile kwe-FT232RL, i-Clock Signal generator kanye nemodyuli yokuphathwa kwamandla kuhlanganiswe ngaphakathi kwalo.I-Clock Signal Generator inesibopho sokuhlinzeka amasiginali wewashi adingekayo kumamojula ahlukahlukene ngaphakathi kwe-chip ukuqinisekisa ukuthi angasebenzisana.Imodyuli yokuphathwa kwamandla inesibopho sokuphatha nokulawula ukunikezwa kwamandla kwe-chip ukuqinisekisa ukuthi i-chip isebenza ngaphakathi kwamandla athile aqinile kanye nobubanzi bamanje.
Isikhombimsebenzisi se-USB
Isibonisi se-USB se-FT232RL sibhekele ukuxhumana kwe-USB nekhompyutha.Isibonisi siqukethe imigqa yedatha ye-USB, i-USB Interface Control Logic kanye namasekethe ahlobene nokuhlonza idivaysi ye-USB.Isibonisi se-USB singathola idatha ye-USB kwikhompyutha bese sidlulisela idatha kwiyunithi yokucubungula ngaphakathi kwe-chip.Ngasikhathi sinye, futhi singadlulisela idatha ekhiqizwa ngaphakathi kwe-chip ibuyele kwikhompyutha ngesikhathi ukuze ifinyelele ekuxhumaneni kwezindlela ezimbili.
Umgomo osebenzayo we-FT232RL ungahlukaniswa ngezinyathelo ezilandelayo.Okokuqala ukuqamba ukuxhumana kwe-USB.Lapho i-FT232RL ifakwe ethekwini le-USB lekhompyutha, lizoqala ukuxhumana kwe-USB nekhompyutha.Ngalesi sikhathi, ikhompyutha izokwamukela i-FT232RL njengedivaysi evumelekile ye-USB bese isikwabela ikheli elihlukile.Lokhu kulandelwa ngokushesha ukudluliswa kwedatha ye-USB.Lapho ukuqaliswa sekuqediwe, idatha ingadluliselwa phakathi kwe-FT232RL kanye nekhompyutha nge-interface ye-USB.Lapho ikhompyutha idinga ukuthumela idatha ku-FT232RL, imininingwane idluliselwa ku-chip ngaphakathi kulayini we-USB.Ngokufanayo, lapho i-FT232RL idinga ukuthumela idatha kwikhompyutha, izothumela imininingwane ngomugqa we-USB.Lokhu kulandelwa ukuguqulwa kwedatha ye-serial.I-FT232RL ine-interface ehlanganisiwe ye-UART ngaphakathi kwe-Chip, umsebenzi wayo owukuguqula idatha ehambisanayo edluliselwe kwi-interface ye-USB ibe yidatha ye-serial, noma ukuguqula idatha ye-serial ibuyele idatha ehambisanayo.Ngale ndlela, i-FT232RL ibona ukuguqulwa kwefomethi yedatha phakathi kwe-USB ne-serial interface.Ngemuva kwalokho kuza ukuxhumana kwe-serial.Ngokusebenzisa isikhombimsebenzisi se-serial se-FT232RL, abasebenzisi bangaxhuma kalula amadivayisi we-serial angaphandle, njengama-miccocontroller noma amanye amadivaysi anomsebenzi wokuxhumana nge-serial.I-FT232RL ingathumela idatha etholakele kula madivaysi angaphandle ngesibonisi se-serial, futhi ngasikhathi sinye, futhi ingathola idatha yedivayisi yangaphandle ethumela ngokusebenzisa isikhombimsebenzisi se-serial, futhi idlulise le datha kwi-interface ye-USB.Ekugcineni, kukhona ukwesekwa komshayeli.Ukuze uqinisekise ukuthi ikhompyutha ingabona kahle futhi ixhumane ne-FT232RL, umsebenzisi udinga ukufaka abashayeli abafanisayo.Labashayeli bahlinzeka nge-protocol edingekayo nokusekelwa okubonakalayo kokuxhumana phakathi kohlelo lokusebenza lwekhompyutha kanye ne-FT232RL.Ngokufaka abashayeli, ikhompyutha izokwazi ukubona nokuphatha i-FT232RL ukuze isebenze kahle.
