Uyazi ukuthi i-LED IC yenzelwe ini?

I-Light Emitting Diode Integrated Circuit ibizwa ngokuthi i-LED IC. Luhlobo lwesekethe ehlanganisiwe eyenzelwe ukulawula nokushayela ama-LED, noma ama-diode akhipha ukukhanya. Amasekethe ahlanganisiwe e-LED (ama-IC) anikeza imisebenzi ehlukahlukene, okuhlanganisa ukulawulwa kwamandla kagesi, ukufiphaza, kanye nokulawula kwamanje, okusiza ukuphathwa okunembile nokusebenza kahle kwezinhlelo zokukhanyisa ze-LED. Izicelo zala masekethe ahlanganisiwe (ama-IC) zifaka amaphaneli okubonisa, izinto zokukhanyisa, kanye nokukhanya kwezimoto.
Isifinyezo se-Integrated Circuit yi-IC. Iyidivayisi encane kagesi eyakhiwe izingxenye eziningi ezenziwe nge-semiconductor, kufaka phakathi ama-resistor, ama-transistors, ama-capacitor, kanye nezinye izifunda ze-elekthronikhi. Imisebenzi ye-elekthronikhi ehlanganisa ukukhulisa, ukushintsha, ukulawulwa kwamandla kagesi, ukucubungula isignali, kanye nokugcina idatha yimisebenzi eyinhloko yesifunda esihlanganisiwe (IC). Imikhiqizo eminingi ye-elekthronikhi, njengamakhompyutha, omakhalekhukhwini, omabonakude, imishini yezokwelapha, izinhlelo zezimoto, nokuningi, isebenzisa izifunda ezihlanganisiwe (ama-IC). Ngokuhlanganisa izingxenye eziningana zibe yi-chip eyodwa, zivumela amagajethi kagesi ukuba abe mancane, asebenze kangcono, futhi asebenzise amandla amancane. Izinhlelo eziningi ze-elekthronikhi manje zisebenzisa ama-IC njengento ebalulekile yokwakha, eguqula umkhakha we-elekthronikhi.

Ama-IC eza ngezindlela ezahlukene, ngalinye lihloselwe ukusetshenziswa kanye nenhloso ethile. Nazi izinhlobo ezimbalwa ezidumile zama-IC:

Ama-MCU: Lawa masekethe ahlanganisiwe aqukethe i-microprocessor core, imemori, kanye ne-peripherals konke ku-chip eyodwa. Anikeza amadivayisi ubuhlakani nokulawula futhi asetshenziswa ezinhlelweni ezahlukahlukene ezifakiwe.

Amakhompyutha nezinye izinhlelo eziyinkimbinkimbi zisebenzisa ama-microprocessors (ama-MPU) njengamayunithi awo okucubungula aphakathi (ama-CPU). Benza izibalo kanye nemiyalelo yemisebenzi eyahlukahlukene.

Ama-DSP IC aklanyelwe ngqo ukucutshungulwa kwezimpawu zedijithali, njengokusakazwa komsindo nevidiyo. Avame ukusetshenziswa ezinhlelweni zokusebenza ezifana nokucubungula izithombe, imishini yomsindo, kanye nokuxhumana ngocingo.
Amasekethe Ahlanganisiwe Akhethekile (ama-ASIC): Ama-ASIC ayisekethe ahlanganisiwe enziwe ngokukhethekile ahloselwe ukusetshenziswa noma izinjongo ezithile. Anikeza ukusebenza okuhle kakhulu ngenhloso ethile futhi avame ukutholakala kumadivayisi akhethekile njengezinhlelo zokuxhumana kanye nemishini yezokwelapha.

Ama-Field-Programmable Gate Arrays, noma ama-FPGA, ayizifunda ezihlanganisiwe ezihlelekayo ezingasethwa ukuze zenze imisebenzi ethile ngemva kokuba sezikhiqizwe. Ziyakwazi ukuzivumelanisa nezimo futhi zinezinketho eziningi zokuhlela kabusha.

Amasekethe ahlanganisiwe e-Analog (ama-IC): Lawa madivayisi acubungula izimpawu eziqhubekayo futhi asetshenziswa ekulawulweni kwamandla kagesi, ekukhuliseni, nasekuhlungeni izinhlelo zokusebenza. Izilawuli zama-voltage, ama-amplifiers omsindo, kanye nama-amplifiers okusebenza (ama-op-amps) ziyizibonelo ezimbalwa.
Ama-IC anememori angagcina futhi athole idatha. Imemori Yokufunda Okuhleliwe Engasuswa Ngogesi (EEPROM), imemori ye-Flash, imemori Yokufinyelela Okungahleliwe (SRAM), kanye ne-Dynamic Random Access Memory (DRAM) ziyizibonelo ezimbalwa.

Ama-IC asetshenziswa ekuphathweni kwamandla: Lawa ma-IC alawula futhi alawule amandla asetshenziswa kumadivayisi kagesi. Ukulawula ukunikezwa kwamandla, ukushaja ibhethri, kanye nokuguqulwa kwamandla kagesi kuphakathi kwemisebenzi asetshenziselwa yona.

Lawa masekethe ahlanganisiwe (ama-IC) avumela ukuxhumana phakathi kwama-domain e-analog nawedijithali ngokuguqula amasignali e-analog abe yidijithali kanye nalawo aphambene nalokho. Aziwa ngokuthi ama-converter e-analog-to-digital (ADC) kanye nama-converter e-digital-to-analog (DAC).

Lokhu kumane kuyizigaba ezimbalwa, futhi insimu yamasekethe ahlanganisiwe (ama-IC) ibanzi kakhulu futhi iyaqhubeka nokukhula njengoba izinhlelo zokusebenza ezintsha kanye nokuthuthuka kwezobuchwepheshe kwenzeka.
