Inkcazo

Isixhobo se-CoolRunner-II i-64-macrocell yenzelwe ukusebenza okuphezulu kunye nezicelo zamandla aphantsi.Oku kuboleka ukonga kwamandla kwizixhobo zonxibelelwano ezikwisiphelo esiphezulu kunye nesantya esiphezulu kwizixhobo ezisebenza ngebhetri.Ngenxa yokuma kwamandla aphantsi kunye nokusebenza okuguquguqukayo, ukuthembeka kwenkqubo ngokubanzi kuyaphuculwa.Esi sixhobo sineebhloko ezine zokuSebenza ezidityaniswe ngamandla aphantsi oQhagamshelwano oluPhezulu lweMatrix (AIM).I-AIM yondla amagalelo angama-40 ayinyani kwaye ancedisana kwiBhloko yoMsebenzi nganye.Iibhloko zoMsebenzi zibandakanya i-40 nge-56 P-term ye-PLA kunye ne-16 macrocells equlethe iibhithi ezininzi zokucwangcisa ezivumela iindlela zokusebenza ezidibeneyo okanye ezibhalisiweyo.Ukongeza, ezi rejista zinokusetwa ngokutsha okanye zisetwe kwangaphambili kwaye ziqwalaselwe njenge-D okanye i-T flip-flop okanye njenge-D latch.Kukwakho nemiqondiso yeewotshi ezininzi, zombini iindidi zexesha lemveliso yehlabathi kunye neyengingqi, ezilungiselelwe ngokwesiseko semacrocell.Ulungelelwaniso lwezikhonkwane zemveliso lubandakanya umyinge wezinga lokubulawa, ukubamba ibhasi, ukutsalwa, ukutsala amanzi, kunye nemihlaba enokucwangciswa.Igalelo le-Schmitt trigger liyafumaneka kwi-input pin nganye.Ukongeza ekugcineni imveliso ye-macrocell, iirejista ze-macrocell zinokumiselwa njengeerejista "zokufaka ngqo" ukugcina imiqondiso ngokuthe ngqo kwizikhonkwane zokufaka.Iwashi iyafumaneka kwi-global okanye kwi-Function Block basis.Iiwotshi ezintathu zehlabathi ziyafumaneka kuzo zonke iibhloko zoMsebenzi njengomthombo wewotshi ehambelanayo.Iirejista zeMacrocell zinokucwangciswa ngokwahlukeneyo ukuze zifikelele kwi-zero okanye kwilizwe elinye.Uluhlu lwehlabathi jikelele / ukusetha kwakhona umgca wolawulo lukwakhona ukuseta okanye ukusetha ngokutsha iirejista ezikhethiweyo ngexesha lokusebenza.Iwotshi yasekhaya eyongezelelweyo, i-clock-enabled clock-enable, i-asynchronous set / reset, kunye nesiphumo senza ukuba izibonakaliso zikwazi ukubunjwa ngokusebenzisa imimiselo yemveliso kwi-macrocell nganye okanye i-Per-Function Block basis.I-DualEDGE flip-flop feature iyafumaneka kwi-macrocell nganye.Eli nqaku livumela ukusebenza okuphezulu kolungelelwaniso olusekwe kwiwashi esezantsi esezantsi ukunceda ukunciphisa usetyenziso lwamandla lulonke lwesixhobo.I-CoolRunner-II i-64-macrocell CPLD yi-I / O iyahambelana ne-LVTTL eqhelekileyo kunye ne-LVCMOS18, i-LVCMOS25, kunye ne-LVCMOS33.Esi sixhobo kwakhona i-1.5VI / O iyahambelana nokusetyenziswa kwe-Schmitt-trigger inputs.Olunye uphawu olulula ukuguqulelwa kwamandla ombane yibhanki ye-I/O.Iibhanki ezimbini ze-I / O ziyafumaneka kwisixhobo se-macrocell se-CoolRunner-II 64A esivumela ukudibanisa okulula kwi-3.3V, 2.5V, 1.8V, kunye ne-1.5V izixhobo.
