Ngexesha lokukhululwa kwenkqubo yechip (amandla-on-reset, i-RTC watchdog ukusetha kwakhona kunye nokusetha kabusha i-brownout), iiletshi zezikhonkwane zokubopha s.ample voltage inqanaba njengamasuntswana okubopha "0" okanye "1", kwaye ubambe la masuntswana de itshiphu inikwe amandla okanye icinywe. Amasuntswana okubopha qwalasela indlela yokuqalisa isixhobo, ivolthi yokusebenzatage ye VDD_SDIO kunye nezinye iisetingi zenkqubo yokuqala. Iphini nganye yokubopha idityaniswe kukutsalwa kwayo kwangaphakathi/ukutsalela phantsi ngexesha lokusetwa kwakhona kwetshiphu. Ngenxa yoko, ukuba isikhonkwane sokubopha asixhunyiwe okanye isiphaluka sangaphandle esidityanisiweyo siphezulu-i-impedance, i-internal weak pull-up-up-down-down iya kugqiba inqanaba legalelo elingagqibekanga leentsimbi zokubopha. Ukutshintsha amaxabiso amasuntswana okubopha, abasebenzisi banokufaka ukutsalwa phantsi/ukutsalwa kwangaphandle, okanye basebenzise iGPIOs yeMCU yomkhosi ukulawula ivolthi.taginqanaba lezi zikhonkwane xa unika amandla kwi-ESP32. Emva kokukhululwa ngokutsha, izikhonkwane zokubopha zisebenza njengezikhonkwane eziqhelekileyo zokusebenza. Jonga kwiTheyibhile yesi-2 yoqwalaselo oluneenkcukacha lwendlela yokuqalisa ngokufaka imitya.

I-8 KB ye-SRAM kwi-RTC, ebizwa ngokuba yi-RTC SLOW Memory kwaye inokufikelela kwi-co-processor ngexesha le-Deep-sleep mode.
I-1 Kbit ye-eFuse: iibits ezingama-256 zisetyenziselwa inkqubo (idilesi ye-MAC kunye noqwalaselo lwetshiphu) kwaye amasuntswana angama-768 ashiyekileyo abekelwe izicelo zabathengi, kubandakanywa uguqulelo oluntsonkothileyo kunye ne-chip-ID.

I-Flash yangaphandle kunye ne-SRAM
I-ESP32 ixhasa iiflash ezininzi zangaphandle ze-QSPI kunye neetshiphusi ze-SRAM. I-ESP32 ikwaxhasa i-hardware encryption/decryption esekwe kwi-AES ukukhusela iinkqubo zabaphuhlisi kunye nedatha kwiFlash.

I-ESP32 inokufikelela kwi-flash ye-QSPI yangaphandle kunye ne-SRAM ngokusebenzisa i-caches enesantya esiphezulu.

I-flash yangaphandle inokuzotywa kwi-CPU yememori yendawo yememori kunye nesithuba sememori yokufunda kuphela ngaxeshanye.
- Xa ifleshi yangaphandle ifakwe kwi-CPU yomyalelo kwisithuba sememori, ukuya kuthi ga kwi-11 MB + 248 KB inokumatshwa ngexesha. Qaphela ukuba ukuba ngaphezulu kwe-3 MB + 248 KB imephu, ukusebenza kwe-cache kuya kuncitshiswa ngenxa yokufundwa okuqikelelwayo yi-CPU.
- Xa ifleshi yangaphandle ifakwe kwimephu yokufunda-kuphela isithuba sememori yedatha, ukuya kuthi ga kwi-4 MB inokumatshwa ngexesha. I-8-bit, i-16-bit kunye ne-32-bit efundwayo iyaxhaswa.
I-SRAM yangaphandle inokuzotywa kwindawo yememori yedatha ye-CPU. Ukuya kuthi ga kwi-4 MB kunokwenziwa imephu ngexesha. I-8-bit, i-16-bit kunye ne-32-bit ifundeka kwaye ibhale iyaxhaswa.

Ulwazi kwiindlela zovavanyo kunye neemfuno zovavanyo ezongezelelweyo
- Umthumeli wemodyuli uvavanywe ngokupheleleyo ngumxhasi wemodyuli kwinani elifunekayo letshaneli, iintlobo zokumodareyitha, kunye neendlela, akufuneki kube yimfuneko ukuba umfakeli womkhosi aphinde avavanye zonke iindlela zokuhambisa ezikhoyo okanye useto. Kwenziwa isincomo sokuba umenzi wemveliso engumamkeli, afakele isidluliseli semodyuli, enze imilinganiselo yophando ukuqinisekisa ukuba inkqubo edityanisiweyo enesiphumo ayigqithi kwimida yokukhutshwayo ebubuxoki okanye imida yomphetho webhendi (umz., apho i-eriyali eyahlukileyo inokubangela ukukhutshwa okungaphezulu).
- Uvavanyo kufuneka lujonge izinto ezikhutshwayo ezinokuthi zenzeke ngenxa yokudityaniswa kwezinto ezikhutshwayo kunye nezinye ii-transmitters, i-digital circuitry, okanye ngenxa yeempawu ezibonakalayo zemveliso yokusingatha (indawo evalelweyo). Olu phando lubaluleke kakhulu xa udibanisa iimodyuli ezininzi zothutho apho uqinisekiso lusekwe ekuvavanyeni ngamnye kubo kuqwalaselo oluzimeleyo. Kubalulekile ukuqaphela ukuba abavelisi beemveliso abasindlekayo akufuneki bacinge ukuba ngenxa yokuba isidluliseli semodyuli siqinisekisiwe abanalo naluphi na uxanduva lokuthotyelwa kwemveliso yokugqibela.
- Ukuba uphando lubonisa inkxalabo yothotyelo, umenzi wemveliso yomkhosi unyanzelekile ukuba awuthobe umba. Iimveliso zokusingatha ezisebenzisa i-modular transmitter zixhomekeke kuyo yonke imithetho esebenzayo yobugcisa kunye neemeko eziqhelekileyo zokusebenza kumaCandelo 15.5, 15.15, kunye ne-15.29 ukuba angabangela ukuphazamiseka. Umsebenzisi wemveliso yenginginya uya kunyanzeleka ukuba ayeke ukusebenzisa isixhobo de uphazamiseko lulungiswe.
Uvavanyo olongezelelweyo, iSahlulo se-15 seCandelwana B isilandulo Umamkeli wokugqibela/udibaniso lwemodyuli kufuneka luvavanywe ngokuchasene nenkqubo yeFCC yeSigaba 15B seeradiyetha ezingenziwanga ngabom ukuze zigunyaziswe ngokufanelekileyo ukuba zisebenze njengeSahlulo se-15 sesixhobo sedijithali.

Umdibanisi ofaka le modyuli kwimveliso yakhe kufuneka aqinisekise ukuba imveliso edibeneyo yokugqibela ihambelana neemfuno zeFCC ngovavanyo lobugcisa okanye uvandlakanyo lwemithetho yeFCC, kuquka nokusebenza kothumelo kwaye kufuneka ibhekiselele kwisikhokelo kwi-KDB 996369. iimodyuli eziqinisekisiweyo zokuhambisa iimodyuli, uluhlu lwamaza ophando lwenkqubo ehlanganisiweyo luchazwa ngumgaqo okwiCandelo le-15.33(a)(1) ukuya ku-(a)(3), okanye uluhlu olusebenzayo kwisixhobo sedijithali, njengoko kubonisiwe kwiCandelo le-15.33(b) )(1), nokuba loluphi na uluhlu oluphezulu lophando Xa uvavanya imveliso yokusingatha, zonke ii-transmitter kufuneka zisebenze. Iitransmitha zinokuvulwa ngokusebenzisa abaqhubi abakhoyo esidlangalaleni kwaye bavulwe, ngoko ke abathumeli bayasebenza. Kwiimeko ezithile, kunokufaneleka ukusebenzisa ibhokisi yokufowuna ethe ngqo kwiteknoloji (iseti yovavanyo) apho i-accessory 50 yezixhobo okanye abaqhubi bangafumanekiyo. Xa kuvavanyelwa izinto ezikhutshwayo kwiradiyetha engenzelwanga ngabom, isidluliseli siya kufakwa kwimowudi yokufumana okanye imo yokungenzi nto, ukuba kunokwenzeka. Ukuba imo yokufumana kuphela ayinakwenzeka ngoko, unomathotholo uya kuba yi-passive (ekhethwayo) kunye/okanye ukuskena okusebenzayo. Kwezi meko, oku kuya kufuneka ukuba kuvuleleke umsebenzi kwi-BUS yonxibelelwano (okt, PCIe, SDIO, USB) ukuqinisekisa ukuba ukujikelezwa kweradiyetha ngokungeyonjongo kuvuliwe. Iilabhoratri zovavanyo zinokufuna ukongeza ukuthomalalisa okanye izihluzi ngokuxhomekeke kumandla omqondiso wazo naziphi na iibhikhoni ezisebenzayo (ukuba ziyasebenza) ukusuka kwi(ii)rediyo ezivuliweyo. Jonga i-ANSI C63.4, ANSI C63.10 kunye ne-ANSI C63.26 ngeenkcukacha ezingaphezulu zovavanyo ngokubanzi.

Imveliso ephantsi kovavanyo isetelwe kwikhonkco/unxulumano kunye nesixhobo sobambiswano, ngokwesiqhelo sokusetyenziswa okucetyiweyo kwemveliso. Ukunciphisa uvavanyo, imveliso ephantsi kovavanyo isetelwe ukusasaza kumjikelo ophezulu, njengokuthumela file okanye usasaza umxholo othile wemidiya.

Isilumkiso seFCC:
Naluphi na uTshintsho okanye uhlengahlengiso olungavunywanga ngokucacileyo liqela elinoxanduva lokuthotyelwa lunokuphelisa igunya lomsebenzisi lokusebenzisa isixhobo. Esi sixhobo sithobela inxalenye ye-15 yeMithetho yeFCC. Ukusebenza kuxhomekeke kwezi meko zimbini zilandelayo: (1) Esi sixhobo asinakubanga luphazamiso luyingozi, kwaye (2) Esi sixhobo kufuneka samkele naluphi na uphazamiseko olufunyenweyo, kubandakanywa uphazamiseko olunokubangela usetyenziso olungafunekiyo.
