4. Taulimaina o pine e le'i fa'aogaina U'u pine e le'i fa'aaogaina e tusa ai ma fa'atonuga o lo'o tu'uina atu i lalo o le tagofiaina o pine e le'i fa'aaogaina i totonu o le tusi lesona. O pine fa'aoga o oloa CMOS e masani lava ile tulaga maualuga-impedance. I le faʻaogaina o se pine e leʻi faʻaaogaina i le tulaga tatala-circuit, o loʻo faʻaosoina le pisapisao electromagnetic i tafatafa o le LSI, o se faʻalavelave faʻafuaseʻi o loʻo tafe i totonu, ma faʻaletonu e tupu ona o le faʻamaonia sese o le pine faʻailoga e mafai ona mafai.
5. Fa'ailo o le Uati A mae'a ona fa'aoga se seti, na'o le fa'amuta o le laina toe fa'afou pe a fa'amautu le fa'ailo o le uati. A fesuia'i le fa'ailo o le uati i le taimi o le fa'atinoina o le polokalame, fa'atali se'i mautu le fa'ailo o le uati. Pe a faia le faailo o le uati i se resonator fafo pe mai se oscillator fafo i le taimi o le toe setiina, ia mautinoa o le toe setiina laina e na o le tatalaina pe a maeʻa le faʻamautuina atoatoa o le faailo o le uati. E le gata i lea, pe a sui i se faailo o le uati na gaosia i se resonator fafo po'o se oscillator fafo a'o fa'agasolo le polokalama, fa'atali se'i mautu le fa'ailo o le uati.
6. Voltagu fa'aoga galu ile pine fa'aofi Fa'aletonu ole galu ona o le pisapisao po'o se galu fa'aalia e ono mafua ai le fa'aletonu. Afai o le faʻaogaina o le masini CMOS e tumau i le va o le VIL (Max.) ma le VIH (Min.) ona o le pisa, mo ex.ample, e ono faaletonu le masini. Faʻaeteete e puipuia le pisa o talatalanoaga mai le ulufale atu i le masini pe a faʻamautu le tulaga faʻaoga ma faʻapea foʻi i le vaitaimi o suiga pe a pasi atu le tulaga faʻaoga i le va o le VIL (Max.) ma le VIH (Min.).
7. 7. Fa'asa o le avanoa i tuatusi fa'aagaga
   E fa'asa le avanoa i tuatusi fa'apolopolo. O tuatusi fa'aagaga o lo'o tu'uina atu mo le fa'alauteleina o galuega i le lumana'i. Aua le fa'aogaina nei tuatusi ona e le fa'amaonia le fa'agaioiga sa'o o le LSI.
8. Eseesega i le va o oloa A'o le'i suia mai le tasi oloa i le isi, mo se'iample, i se oloa e ese le numera vaega, faʻamaonia o le suiga o le a le taʻitaʻia ai faʻafitauli. O uiga o se microprocessing unit poʻo microcontroller unit products i le vaega lava e tasi ae e ese le numera o vaega atonu e eseese i tulaga o le mafaufau i totonu, mamanu faʻatulagaina, ma isi mea, e mafai ona aʻafia ai le laina o uiga eletise, e pei o uiga taua, faʻaogaina laina, puipuiga i le pisa, ma le aofaʻi o le pisa susulu. Pe a sui i se oloa e ese le numera o vaega, faʻatino se suʻega suʻesuʻega mo le oloa tuʻuina atu.
