I-Rockchip yethule i-chip entsha yephrothokholi yokushaja okusheshayo i-RK838, enokunemba okuphezulu kwamanje okungaguquki, ukusetshenziswa kwamandla okuphansi kakhulu, futhi yaphumelela isitifiketi se-UFCS.

Isandulelo

I-chip yephrothokholi iyingxenye ebalulekile futhi ebalulekile yeshaja. Inesibopho sokuxhumana nedivayisi exhunyiwe, okulingana nebhuloho elixhumanisa idivayisi. Ukuqina kwe-chip yephrothokholi kudlala indima ebalulekile kokuhlangenwe nakho kanye nokuthembeka kokushaja okusheshayo.

Muva nje, iRockchip yethule i-protocol chip RK838 enomgogodla weCortex-M0 owakhelwe ngaphakathi, osekela ukushaja okusheshayo kwe-USB-A kanye ne-USB-C dual-port, osekela i-PD3.1, i-UFCS kanye nezinqubo ezahlukahlukene zokushaja okusheshayo ezijwayelekile emakethe, futhi ungafinyelela Amandla okushaja aphezulu kakhulu angama-240W, asekela i-voltage engaguquki ephezulu kanye nokulawula kwamanje okungaguquki kanye nokusetshenziswa kwamandla okulindile okuphansi kakhulu.

I-Rockchip RK838

I-Rockchip RK838 iyi-chip yephrothokholi yokushaja okusheshayo ehlanganisa i-USB PD3.1 kanye ne-UFCS protocol core, efakwe imbobo ye-USB-A kanye nembobo ye-USB-C, isekela ukuphuma okubili kwe-A+C, futhi zombili iziteshi zisekela iphrothokholi ye-UFCS. Inombolo yesitifiketi se-UFCS: 0302347160534R0L-UFCS00034.

I-RK838 isebenzisa ukwakheka kwe-MCU, ihlanganisa ngaphakathi i-Cortex-M0 core, isikhala sokugcina i-flash esikhulu esingu-56K, isikhala se-2K SRAM ukuze kufezwe i-PD kanye nezinye izinqubo zobunikazi, futhi abasebenzisi bangakwazi ukufeza isitoreji sekhodi yephrothokholi eminingi kanye nemisebenzi ehlukahlukene yokuvikela ngokwezifiso.
Uma kukhulunywa ngokushaja okusheshayo okunamandla aphezulu, akuhlukaniseki ngokwemvelo nokulawulwa kwe-voltage okunembe kakhulu. I-RK838 isekela ukuphuma kwe-voltage okungaguquki okungu-3.3-30V, futhi ingafinyelela ukwesekwa kwamanje okungaguquki okungu-0-12A. Uma i-current engaguquki ingaphakathi kuka-5A, iphutha lingaphansi kuka-±50mA.

I-RK838 iphinde ibe nemisebenzi yokuvikela ebanzi eyakhelwe ngaphakathi, phakathi kwayo i-CC1/CC2/DP/DM/DP2/DP2 efaka zonke isekela i-30V ukumelana ne-voltage, engavimbela ngempumelelo imigqa yedatha eyonakele ekubangeleni umonakalo womkhiqizo, futhi isekele ukuvala okusheshayo kokukhipha ngemva kwe-overvoltage. I-chip iphinde ibe nokuvikelwa kwe-overcurrent eyakhelwe ngaphakathi, ukuvikelwa kwe-overvoltage, ukuvikelwa kwe-undervoltage kanye nokuvikelwa kwe-overvoltage ukuqinisekisa ukusetshenziswa okuphephile.
