I-Rockchip yaphehlelela iprotocol entsha ekhawulezayo yokutshaja i-RK838, enokuchaneka okuthe gqolo kwangoku, ukusetyenziswa kwamandla okulinda okusezantsi, kunye nokuphumelela isiqinisekiso se-UFCS.

Intshayelelo

Iprotocol chip yinxalenye eyimfuneko kwaye ibalulekileyo yetshaja. Inoxanduva lokunxibelelana nesixhobo esiqhagamshelweyo, esilingana nebhulorho edibanisa isixhobo. Uzinzo lweprotocol chip ludlala indima eqinisekileyo kumava kunye nokuthembeka kokutshaja ngokukhawuleza.

Kutshanje, i-Rockchip isungule i-protocol chip RK838 enesiseko esakhelwe ngaphakathi seCortex-M0, exhasa i-USB-A kunye ne-USB-C kabini-izibuko ukutshaja ngokukhawuleza, ixhasa iPD3.1, UFCS kunye neendlela ezahlukeneyo zokutshaja okukhawulezayo kwimarike, kwaye inokuqonda Awona mandla aphezulu okutshaja yi-240W, ixhasa i-voltage echanekileyo ephezulu echanekileyo kunye nolawulo lwangoku oluqhubekayo kunye nokusetyenziswa kwamandla okulinda okuphantsi kwe-ultra-low.

Rockchip RK838

I-Rockchip RK838 yiprotocol yokutshaja ngokukhawuleza edibanisa i-USB PD3.1 kunye nondoqo weprotocol ye-UFCS, exhotyiswe nge-USB-A nezibuko le-USB-C, ixhasa i-A+C ephuma kabini, kwaye omabini amajelo axhasa iprotocol ye-UFCS. Inombolo yesatifikethi se-UFCS: 0302347160534R0L-UFCS00034.

I-RK838 ithatha i-architecture ye-MCU, ngaphakathi idibanisa i-Cortex-M0 core, i-56K indawo yokugcina i-flash enkulu, i-2K SRAM indawo yokuqonda i-PD kunye nezinye iiprothokholi zobunikazi, kunye nabasebenzisi banokuqonda ukugcinwa kwekhowudi ye-multi-protocol kunye nemisebenzi eyahlukeneyo yokukhusela isiko.
Xa kufikwa kumandla aphezulu wokutshaja ngokukhawuleza, ayinakwahlulwa ngokwendalo kummiselo wombane ochanekileyo. I-RK838 ixhasa i-voltage eqhubekayo ye-3.3-30V, kwaye inokuqonda inkxaso eqhubekayo ye-0-12A. Xa i-current current ingaphakathi kwe-5A, impazamo ingaphantsi kwe-±50mA.

I-RK838 nayo iye yakha-imisebenzi yokukhusela ebanzi, phakathi kwayo i-CC1 / CC2 / DP / DM / DP2 / DPM2 izikhonkwane zonke zixhasa i-30V ukumelana nombane, onokuthi uthintele ngokufanelekileyo imigca yedatha eyonakalisiweyo ukuba ibangele umonakalo wemveliso, kunye nokuxhasa ukuvala ngokukhawuleza kwemveliso emva kokugqithiswa kombane. . I-chip nayo iye yakha-ngaphakathi ukhuseleko olugqithisiweyo, ukukhuselwa kwe-overvoltage, ukukhuselwa kwe-undervoltage kunye nokukhusela ukufudumala ukuqinisekisa ukusetyenziswa okukhuselekileyo.
