Chida cha CoolRunner-II 64-macrocell chapangidwira kuti chizigwira ntchito kwambiri komanso kugwiritsa ntchito mphamvu zochepa.Izi zimabwereketsa kupulumutsa mphamvu ku zida zoyankhulirana zapamwamba komanso kuthamanga kwambiri pazida zoyendetsedwa ndi batri.Chifukwa cha mphamvu zochepa zoyimilira ndi ntchito zosinthika, kudalirika kwadongosolo lonse kumakula bwino.Chipangizochi chili ndi Ma Function Blocks anayi olumikizidwa ndi mphamvu yochepa ya Advanced Interconnect Matrix (AIM).AIM imadyetsa zolowa 40 zowona ndikuwonjezera pa Function Block iliyonse.Ma Function Blocks amakhala ndi 40 by 56 P-term PLA ndi ma macrocell 16 omwe ali ndi ma bits angapo osinthika omwe amalola kuti azigwira ntchito mophatikiza kapena zolembetsa.Kuphatikiza apo, zolembetsazi zitha kukhazikitsidwanso padziko lonse lapansi kapena kusinthidwa ndikusinthidwa ngati D kapena T flip-flop kapena ngati D latch.Palinso ma siginecha angapo a wotchi, mitundu yanthawi zonse yapadziko lonse komanso yapadziko lonse lapansi, yokhazikitsidwa pa macrocell.Kukonzekera kwa pini zotulutsa kumaphatikizapo malire opha anthu, kunyamula mabasi, kukokera m'mwamba, kukhetsa kotseguka, ndi malo okonzekera.Choyambitsa cha Schmitt chimapezeka pa pini iliyonse.Kuphatikiza pakusunga zotulutsa za macrocell, zolembera za macrocell zitha kukhazikitsidwa ngati zolembera "zolowera mwachindunji" kuti zisunge ma siginecha kuchokera pamapini olowera.Kutseka kumapezeka padziko lonse lapansi kapena Function Block maziko.Mawotchi atatu apadziko lonse lapansi akupezeka pa Function Blocks onse ngati gwero la wotchi yofananira.Ma regista a Macrocell amatha kukhazikitsidwa payekhapayekha kuti azitha kufika pa zero kapena dziko limodzi.Mzere wapadziko lonse lapansi wowongolera / kukonzanso kumapezekanso kuti mukhazikitse mwachisawawa kapena kukonzanso zolembetsa zosankhidwa panthawi yogwira ntchito.Wotchi yowonjezera yakumaloko, wotchi yolumikizira yolumikizirana, kuyika / kukonzanso mosagwirizana, ndi zotulutsa zimathandizira kuti zizindikilo zitha kupangidwa pogwiritsa ntchito mawu opangira pa macrocell kapena pa-Function Block.Mbali ya DualEDGE flip-flop imapezekanso pa macrocell.Izi zimathandiza kuti pakhale ntchito yolumikizirana kwambiri potengera mawotchi ocheperako kuti achepetse kugwiritsa ntchito mphamvu zonse za chipangizocho.CoolRunner-II 64-macrocell CPLD ndi I/O yogwirizana ndi LVTTL ndi LVCMOS18, LVCMOS25, ndi LVCMOS33.Chipangizochi chilinso ndi 1.5VI/O chogwirizana ndi kugwiritsa ntchito zolowetsa za Schmitt-trigger.Chinthu chinanso chomwe chimathandizira kumasulira kwamagetsi ndi banki ya I/O.Mabanki awiri a I/O akupezeka pa chipangizo cha CoolRunner-II 64A macrocell chomwe chimalola kulumikizana kosavuta kwa 3.3V, 2.5V, 1.8V, ndi 1.5V.
