XC2C64A-7VQG100C IC CPLD 64MC 6.7NS 100VQFP

Ibisobanuro

Igikoresho cya CoolRunner-II 64-macrocell cyakozwe kubikorwa byombi ndetse nimbaraga nke zikoreshwa.Ibi bitanga ingufu zo kuzigama ibikoresho byitumanaho byohejuru kandi byihuta kubikoresho bikoresha bateri.Bitewe nimbaraga nke zihagarara hamwe nibikorwa bikora, muri rusange sisitemu yo kwizerwa iratera imbere.Iki gikoresho kigizwe na bine Imikorere ihujwe nimbaraga nkeya Advanced Interconnect Matrix (AIM).AIM igaburira 40 yukuri kandi yuzuza inyongeramusaruro kuri buri gikorwa cyo guhagarika.Imikorere ya Block igizwe na 40 kuri 56 P-manda ya PLA na macrocells 16 zirimo ibice byinshi byimiterere byemerera guhuza cyangwa kwiyandikisha mubikorwa.Byongeye kandi, ibi bitabo birashobora gusubirwamo kwisi yose cyangwa kugenwa no kugenwa nka D cyangwa T flip-flop cyangwa nka D latch.Hariho kandi ibimenyetso byinshi byamasaha, haba kwisi yose hamwe nibicuruzwa byigihe byubwoko, byashizweho kuri macrocell.Ibisohoka pin iboneza birimo igipimo ntarengwa, gufata bisi, gukurura, gufungura imiyoboro, hamwe nimpamvu zishobora gutegurwa.A Schmitt imbarutso yinjiza irahari kumurongo winjiza pin.Usibye kubika macrocell yasohotse ivuga, rejisitiri ya macrocell irashobora gushyirwaho nkiyandikwa rya "direct input" kugirango ibike ibimenyetso biturutse kumapine yinjira.Isaha iraboneka kwisi yose cyangwa Imikorere yo guhagarika.Amasaha atatu kwisi arahari kubikorwa byose bifunga nkisoko yisaha ihuza.Ibitabo bya Macrocell birashobora gushyirwaho kugiti cyawe kugirango bigere kuri zeru cyangwa leta imwe.Kwisi yose gushiraho / gusubiramo umurongo wo kugenzura nabyo birahari kugirango ushireho cyangwa usubiremo ibitabo byatoranijwe mugihe gikora.Isaha yinyongera yaho, isaha ihuza-ishoboza, gushiraho / gusubiramo, hamwe nibisohoka bituma ibimenyetso bishobora gushirwaho ukoresheje amagambo yibicuruzwa kuri macrocell cyangwa kuri buri mikorere yo guhagarika.Ikiranga DualEDGE flip-flop nayo iraboneka kuri macrocell.Iyi mikorere ituma imikorere ikomatanya ikora ishingiye kumasaha yo hasi kugirango ifashe kugabanya ingufu zose zikoreshwa mubikoresho.CoolRunner-II 64-macrocell CPLD ni I / O ihuza na LVTTL na LVCMOS18, LVCMOS25, na LVCMOS33.Iki gikoresho nacyo 1.5VI / O gihujwe no gukoresha Schmitt-trigger inyongeramusaruro.Ikindi kintu cyoroshya ibisobanuro bya voltage ni I / O banki.Amabanki abiri ya I / O araboneka ku gikoresho cya macrocell ya CoolRunner-II 64A yemerera guhuza byoroshye na 3.3V, 2.5V, 1.8V, na 1.5V.
