Tsanangudzo

Iyo CoolRunner-II 64-macrocell mudziyo wakagadzirirwa ese ari maviri epamusoro kuita uye yakaderera magetsi maapplication.Izvi zvinokweretesa kuchengetedza kwemagetsi kune yakakwirira-yekupedzisira yekutaurirana michina uye kumhanya kwakanyanya kumidziyo inoshandiswa nebhatiri.Nekuda kweiyo yakaderera simba kumira-ne uye ine simba kushanda, yakazara system kuvimbika kunovandudzwa.Mudziyo uyu une maFuncction Blocks mana akabatana neine simba shoma Advanced Interconnect Matrix (AIM).Iyo AIM inodyisa makumi mana echokwadi uye anopindirana mapindiro kune yega yega Basa reBasa.Iwo Mashandiro Mabhuroki anoumbwa ne40 ne56 P-temu PLA uye gumi nematanhatu macrocells ane akawanda mabheti ekugadzirisa anobvumira kusanganisa kana kunyoreswa maitiro ekushanda.Pamusoro pezvo, marejista aya anogona kugadziridzwa pasi rose kana kusetwa uye kugadziridzwa seD kana T flip-flop kana seD latch.Kune zvakare akawanda masaini masiginecha, ese epasi uye emuno chigadzirwa term mhando, akagadzirirwa pane macrocell hwaro.Kubuda kwepini masisitimu anosanganisira akauraya mwero, kubata bhazi, kudhonza-kumusoro, kuvhura drain, uye programmable zvikonzero.A Schmitt trigger input inowanikwa pane imwe pini yekuisa.Pamusoro pekuchengetedza macrocell anobuda nyika, iwo macrocell marejista anogona kugadzirwa se "yakananga yekupinza" marejista kuchengetedza masaini zvakananga kubva kumapini ekupinza.Kuvhara kunowanikwa pasi rose kana Function Block base.Wachi nhatu dzepasirese dziripo kune ese maFundo Mabhuroki seyakafanana wachi sosi.Macrocell marejista anogona kugadzirwa ega kuti asvike ku zero kana imwe nyika.A global set/reset control line inowanikwawo kuti asynchronously kuseta kana kuseta zvakare maregister akasarudzwa panguva yekushanda.Yekuwedzera wachi yemuno, inopindirana wachi-inogonesa, asynchronous set/reset, uye zvinobuda zvinogonesa masaini anogona kuumbwa uchishandisa chigadzirwa mazwi pane per-macrocell kana per-Function Block hwaro.Iyo DualEDGE flip-flop chimiro inowanikwawo pane macrocell.Iyi ficha inobvumira yakakwira kuita synchronous mashandiro anoenderana neakaderera frequency wachi yekubatsira kudzikisa simba rose rekushandisa kwechishandiso.Iyo CoolRunner-II 64-macrocell CPLD ndeye I/O inoenderana neyakajairwa LVTTL uye LVCMOS18, LVCMOS25, uye LVCMOS33.Ichi chishandiso zvakare 1.5VI/O chinowirirana nekushandiswa kweSchmitt-trigger inputs.Chimwe chinhu chinorerutsa kushandura kwevoltage iI/O banking.Mabhangi maviri eI/O anowanikwa paCoolRunner-II 64A macrocell mudziyo unobvumidza kupindirana kuri nyore kune 3.3V, 2.5V, 1.8V, uye 1.5V zvishandiso.
