Incazelo

Idivayisi ye-CoolRunner-II 64-macrocell yakhelwe kokubili ukusebenza okuphezulu kanye nezicelo zamandla aphansi.Lokhu kunikeza ukonga amandla kumishini yokuxhumana ephezulu kanye nesivinini esikhulu kumadivayisi asebenza ngamabhethri.Ngenxa yokuma okuphansi kwamandla nokusebenza okuguquguqukayo, ukwethembeka kwesistimu jikelele kuyathuthukiswa.Lolu cingo luqukethe ama-Function Blocks amane axhunywe phakathi kwamandla aphansi i-Advanced Interconnect Matrix (AIM).I-AIM iphakela okokufaka okungama-40 kweqiniso nokuhambisanayo ku-Function Block ngayinye.Ama-Function Blocks aqukethe i-P-term engama-40 by 56 kanye nama-macrocell angu-16 aqukethe izingcezu zokucushwa eziningi ezivumela izindlela zokusebenza ezihlanganisiwe noma ezibhalisiwe.Ukwengeza, lawa marejista angasethwa kabusha emhlabeni wonke noma asethwe kusengaphambili futhi amiswe njenge-D noma i-T flip-flop noma njenge-D latch.Kukhona futhi amasiginali wewashi amaningi, zombili izinhlobo zethemu lomkhiqizo wasekhaya newasendaweni, alungiselelwe ngesisekelo se-macrocell ngayinye.Ukulungiselelwa kwephini lokuphumayo kufaka umkhawulo wesilinganiso sokubulawa, ukubanjwa kwebhasi, ukudonsela phezulu, idrayivu evulekile, nezizathu ezihlelekayo.I-Schmitt trigger input iyatholakala ngephini ngalinye.Ngokungeziwe ekugcineni izifunda zokukhishwa kwe-macrocell, amarejista ama-macrocell angahlelwa njengamarejista "okufaka okuqondile" ukuze agcine amasiginali ngokuqondile kumaphini okokufaka.Ukuvala iwashi kuyatholakala emhlabeni jikelele noma ku-Function Block basis.Amawashi amathathu omhlaba ayatholakala kuwo wonke ama-Function Blocks njengomthombo wewashi ovumelanisiwe.Amarejista e-Macrocell angacushwa ngawodwana ukuze afinyelele kuziro noma esifundeni esisodwa.Ulayini wokulawula wokusetha/wokusetha kabusha womhlaba nawo uyatholakala ukuze usethe ngokuzenzakalelayo noma usethe kabusha amarejista akhethiwe phakathi nokusebenza.Iwashi lasendaweni elengeziwe, amandla ewashi avunyelanisiwe, ukusetha/ukusetha kabusha okuhambisanayo, kanye nokukhipha amandla amasiginali kungakhiwa kusetshenziswa imigomo yomkhiqizo ngesisekelo se-macrocell ngayinye noma Ukuvimbela Umsebenzi ngamunye.Isici se-DualEDGE flip-flop siyatholakala ngesisekelo se-macrocell ngayinye.Lesi sici sivumela ukusebenza okuphezulu kokuvumelanisa okusekelwe ekuvaleni kwewashi okuphansi ukusiza ukwehlisa isamba sokusetshenziswa kwamandla kwedivayisi.I-CoolRunner-II 64-macrocell CPLD i-I/O iyahambisana ne-LVTTL ejwayelekile kanye ne-LVCMOS18, LVCMOS25, kanye ne-LVCMOS33.Le divayisi futhi i-1.5VI/O iyahambisana nokusetshenziswa kokokufaka kwe-Schmitt-trigger.Esinye isici esenza kube lula ukuhunyushwa kwe-voltage i-I/O banking.Amabhange amabili e-I/O ayatholakala kudivayisi ye-macrocell ye-CoolRunner-II 64A evumela ukuxhumana okulula kumadivayisi we-3.3V, 2.5V, 1.8V, kanye ne-1.5V.
