Uyazi ukuthi i-LED IC ingeyani?

I-Light Emitting Diode Integrated Circuit ibizwa nge-LED IC. Iwuhlobo lwesekethe ehlanganisiwe eyenziwe ikakhulukazi ukulawula nokushayela ama-LED, noma ama-diode akhipha ukukhanya. Amasekethe ahlanganisiwe e-LED (ICs) anikezela ngezinhlobonhlobo zemisebenzi, okuhlanganisa ukulawulwa kwamandla kagesi, ukufiphala, nokulawula kwamanje, okusiza ukuphathwa okunembile nokuphumelelayo kwezinhlelo zokukhanyisa ze-LED. Izicelo zalawa masekethi ahlanganisiwe (ama-IC) afaka amaphaneli wokubonisa, izinto zokukhanyisa, nokukhanya kwemoto.
Isifinyezo se-Integrated Circuit sithi IC. Iwumshini omncane we-elekthronikhi owenziwe izingxenye eziningi ezakhiwe nge-semiconductor, okuhlanganisa ama-resistors, ama-transistors, ama-capacitor, namanye amasekhethi kagesi. Imisebenzi ye-elekthronikhi ehlanganisa ukukhulisa, ukushintsha, ukulawulwa kwamandla kagesi, ukucubungula amasignali, nokugcinwa kwedatha kuyimisebenzi eyinhloko yesekethe ehlanganisiwe (IC).Imikhiqizo eminingi ye-elekthronikhi, njengamakhompyutha, omakhalekhukhwini, omabonakude, okokusebenza kwezokwelapha, amasistimu ezimoto, nokunye, kuyaqashwa. amasekhethi ahlanganisiwe (ICs). Ngokuhlanganisa izingxenye ezimbalwa zibe i-chip eyodwa, zivumela amagajethi kagesi ukuthi abe mancane, enze kangcono, futhi asebenzise amandla amancane. Amasistimu amaningi e-elekthronikhi manje asebenzisa ama-IC njengento ebalulekile yokwakha, eguqula umkhakha wezogesi.

Ama-IC eza ngezinhlobo ezehlukene, ngayinye ihloselwe ukusetshenziswa nenjongo ethile. Okulandelayo izinhlobo ezimbalwa ezidumile zama-IC:

Ama-MCU: Lawa masekethi ahlanganisiwe ahlanganisa i-microprocessor core, inkumbulo, nama-peripherals konke ku-chip eyodwa. Banikeza amadivaysi ubuhlakani nokulawula futhi asetshenziswa kumasistimu ashumekiwe ahlukahlukene.

Amakhompyutha nezinye izinhlelo eziyinkimbinkimbi zisebenzisa ama-microprocessors (MPUs) njengamayunithi awo okucubungula amaphakathi (CPUs). Benza izibalo neziyalezo zemisebenzi eyahlukene.

Ama-DSP IC aklanyelwe ngqo ukucutshungulwa kwamasiginali edijithali, njengokusakazwa komsindo nevidiyo. Zisetshenziswa kaningi ezinhlelweni ezinjengokucubungula izithombe, okokusebenza okulalelwayo, kanye nezokuxhumana.
I-Application-Specific Integrated Circuits (ASICs): Ama-ASIC amasekhethi enziwe ngokukhethekile ahloselwe ukusetshenziswa noma izinjongo ezithile. Zihlinzeka ngokusebenza okuphelele ngenjongo ethile futhi zivame ukutholakala kumadivayisi akhethekile njengamasistimu enethiwekhi namathuluzi ezokwelapha.

Ama-Field-Programmable Gate Arrays, noma ama-FPGAs, amasekethe ahlanganisiwe ahlelekayo angase amiswe ukuze enze imisebenzi ethile ngemva kokwakhiwa. Ziyakwazi ukuzivumelanisa nezimo futhi zinezinketho eziningi zokuhlela kabusha.

Amasekhethi ahlanganisiwe e-Analog (ICs): Lawa madivayisi acubungula amasignali aqhubekayo futhi asetshenziswa ekulawuleni amandla kagesi, ekukhuliseni nasekuhlungeni izinhlelo zokusebenza. Izilawuli zamandla kagesi, izikhulisamandla zomsindo, nezikhulisamandla zokusebenza (ama-op-amps) ziyizibonelo ezimbalwa.
Ama-IC anenkumbulo angagcina futhi abuyise idatha. Inkumbulo Efundeka Kuphela Esuseka Ngogesi (EEPROM), inkumbulo ye-Flash, Inkumbulo Yokufinyelela Engahleliwe (SRAM), kanye Nenkumbulo Yokufinyelela Engahleliwe Enamandla (i-DRAM) ziyizibonelo ezimbalwa.

Ama-IC asetshenziswa ekuphathweni kwamandla: Lawa ma-IC alawula futhi alawula amandla asetshenziswa kuzinto zikagesi. Ukulawulwa kokuphakelwa kwamandla, ukushaja ibhethri, nokuguqulwa kwamandla kagesi kuphakathi kwemisebenzi ezisetshenziselwa yona.

Lawa masekethi ahlanganisiwe (ama-IC) anika amandla isixhumanisi phakathi kwesizinda se-analog nedijithali ngokuguqula amasignali e-analog abe yidijithali futhi okuphambene nalokho. Zaziwa njengeziguquli ze-analog-to-digital (ADC) kanye neziguquli ze-digital-to-analog (DAC).

Lezi yizigaba ezimbalwa kuphela, futhi inkambu yamasekhethi ahlanganisiwe (ICs) ibanzi kakhulu futhi ilokhu ikhula njengoba izinhlelo zokusebenza ezintsha kanye nempumelelo yezobuchwepheshe kwenzeka.
