I-Rockchip iqalise i-chip entsha ye-protocol yokutshaja ngokukhawuleza i-RK838, echanekileyo kakhulu, ukusetyenziswa kwamandla okuhlala ixesha elide, kwaye iphumelele isiqinisekiso se-UFCS.

Intshayelelo

I-chip yeprotocol iyinxalenye ebalulekileyo neyimfuneko kwitshaja. Inoxanduva lokunxibelelana nesixhobo esiqhagamshelweyo, esilingana nebhulorho edibanisa isixhobo. Uzinzo lwe-chip yeprotocol ludlala indima ebalulekileyo kumava kunye nokuthembeka kokutshaja ngokukhawuleza.

Kutshanje, iRockchip iqalise i-protocol chip RK838 ene-Cortex-M0 core eyakhelwe ngaphakathi, exhasa ukutshaja ngokukhawuleza kwe-USB-A kunye ne-USB-C dual-port, ixhasa i-PD3.1, i-UFCS kunye neendlela ezahlukeneyo zokutshaja ngokukhawuleza ezikwimarike, kwaye inokufezekisa amandla aphezulu okutshaja yi-240W, ixhasa i-voltage echanekileyo ephezulu kunye nolawulo lwangoku oluqhubekayo kunye nokusetyenziswa kwamandla okulindileyo okuphantsi kakhulu.

I-Rockchip RK838

I-Rockchip RK838 yitshiphu yeprotocol yokutshaja ngokukhawuleza edibanisa i-USB PD3.1 kunye ne-UFCS protocol core, exhotyiswe nge-USB-A port kunye ne-USB-C port, ixhasa i-A+C dual output, kwaye zombini iitshaneli zixhasa i-UFCS protocol. Inombolo yesatifikethi se-UFCS: 0302347160534R0L-UFCS00034.

I-RK838 yamkela uyilo lwe-MCU, idibanisa ngaphakathi i-Cortex-M0 core, indawo yokugcina i-flash enkulu ye-56K, indawo ye-2K SRAM yokuphumeza i-PD kunye nezinye iiprotokholi ezizimeleyo, kwaye abasebenzisi banokufezekisa ukugcinwa kwekhowudi yeprotocol ezininzi kunye nemisebenzi eyahlukeneyo yokukhusela ngokwezifiso.
Xa kufikwa ekutshajeni ngokukhawuleza okunamandla aphezulu, ngokwemvelo ayinakwahlulwa kulawulo lwevolthi oluchanekileyo. I-RK838 ixhasa ukuphuma kwevolthi engaguqukiyo ye-3.3-30V, kwaye inokufezekisa inkxaso yangoku engaguqukiyo ye-0-12A. Xa i-current engaguqukiyo ingaphakathi kwe-5A, impazamo ingaphantsi kwe-±50mA.

I-RK838 ikwanazo nemisebenzi yokhuseleko eyakhelwe ngaphakathi, apho iiphini ze-CC1/CC2/DP/DM/DP2/DPM2 zonke zixhasa i-30V ukumelana ne-voltage, enokuthintela ngempumelelo imigca yedatha eyonakeleyo engabangela umonakalo kwimveliso, kwaye ixhase ukuvalwa ngokukhawuleza kokuphuma emva kwe-overvoltage. Itshiphu ikwanazo nokhuseleko lwe-overcurrent eyakhelwe ngaphakathi, ukhuseleko lwe-overvoltage, ukhuseleko lwe-undervoltage kunye nokhuseleko lwe-overcurrent ukuqinisekisa ukusetyenziswa ngokukhuselekileyo.
