Isandulelo
I-chip yephrothokholi iyingxenye ebalulekile futhi ebalulekile yeshaja.Inesibopho sokuxhumana nedivayisi exhunyiwe, okulingana nebhuloho elixhuma idivayisi.Ukuzinza kwe-chip yephrothokholi kudlala indima ebalulekile kulwazi nokuthembeka kokushaja okusheshayo.
Muva nje, i-Rockchip yethule i-protocol chip RK838 enomongo owakhelwe ngaphakathi we-Cortex-M0, esekela ukushaja okusheshayo kwe-USB-A kanye ne-USB-C, esekela i-PD3.1, UFCS kanye nemithethonqubo ehlukahlukene yokushaja okusheshayo emakethe, futhi ingabona Amandla okushaja aphakeme kakhulu angu-240W, asekela i-voltage engaguquki enembayo ephezulu kanye nokulawula kwamanje okungaguquki kanye nokusetshenziswa kwamandla okulindile aphansi kakhulu.
I-Rockchip RK838
I-Rockchip RK838 iyiphrothokholi eshesha ukushaja ehlanganisa i-USB PD3.1 nephrothokholi ye-UFCS, efakwe imbobo ye-USB-A nembobo ye-USB-C, isekela okukhiphayo okukabili kwe-A+C, futhi zombili iziteshi zisekela umthetho olandelwayo we-UFCS .Inombolo yesitifiketi se-UFCS: 0302347160534R0L-UFCS00034.
I-RK838 yamukela i-architecture ye-MCU, ihlanganisa ngaphakathi i-Cortex-M0 core, indawo yokugcina ye-flash engu-56K enkulu, indawo engu-2K SRAM ukuze ibone i-PD nezinye izivumelwano zobunikazi, futhi abasebenzisi bangathola ukugcinwa kwamakhodi amaningi kanye nemisebenzi ehlukahlukene yokuvikela ngokwezifiso.
Uma kukhulunywa ngokushaja okusheshayo kwamandla aphezulu, ngokwendalo ayinakuhlukaniswa nokulawulwa kwamandla kagesi okunemba okuphezulu.I-RK838 isekela ukuphuma kwamandla kagesi okungaguquki okungu-3.3-30V, futhi ingathola ukusekelwa okuqhubekayo kwamanje kwe-0-12A.Uma i-current eqhubekayo ingaphakathi kwe-5A, iphutha lingaphansi kuka-±50mA.
I-RK838 futhi inemisebenzi ebanzi yokuvikela eyakhelwe ngaphakathi, phakathi kwayo i-CC1/CC2/DP/DM/DP2/DPM2 izikhonkwane zonke zisekela i-30V ukumelana nogesi, ezingavimbela ngempumelelo imigqa yedatha eyonakele ekubangeleni umonakalo womkhiqizo, futhi isekele ukuvala ngokushesha kokuphumayo ngemva kokugcwala ngokweqile. .I-chip iphinde ibe nokuvikelwa kwe-overcurrent eyakhelwe ngaphakathi, ukuvikelwa kwe-overvoltage, ukuvikelwa kwe-undervoltage kanye nokuvikela ukushisa ngokweqile ukuze kuqinisekiswe ukusetshenziswa okuphephile.
