Rockchip yakatanga itsva inokurumidza kuchaja protocol chip RK838, ine yakakwira inogara iripo, mashandisiro emagetsi ekupedzisira-akaderera, uye yakapfuura UFCS certification.

Nhanganyaya

Iyo protocol chip chinhu chakakosha uye chakakosha chikamu chejaja.Inoita basa rekutaurirana nemudziyo wakabatana, wakaenzana nebhiriji rinobatanidza mudziyo.Iko kugadzikana kweprotocol chip inoita basa rakasimba muchiitiko uye kuvimbika kwekuchaja nekukurumidza.

Nguva pfupi yadarika, Rockchip yakatanga chirongwa cheprotocol RK838 ine yakavakirwa-mukati Cortex-M0 musimboti, inotsigira USB-A uye USB-C mbiri mbiri-port yekuchaja nekukurumidza, inotsigira PD3.1, UFCS uye akasiyana-siyana makuru ekuchaja mapuroteni pamusika, uye inogona kuziva Iyo yepamusoro yekuchaja simba ndeye 240W, inotsigira yakakwirira-chaiyo inogara voltage uye inogara iripo kutonga uye yekupedzisira-yakaderera standby mashandisiro emagetsi.

Rockchip RK838

Rockchip RK838 inokurumidza kuchaja protocol chip inobatanidza USB PD3.1 uye UFCS protocol musimboti, ine USB-A chiteshi uye USB-C chiteshi, inotsigira A+C mbiri kuburitsa, uye ese machaneli anotsigira UFCS protocol.Nhamba yetifiketi yeUFCS: 0302347160534R0L-UFCS00034.

RK838 inotora dhizaini yeMCU, yemukati inobatanidza Cortex-M0 musimboti, 56K hombe-inotakura flash yekuchengetera nzvimbo, 2K SRAM nzvimbo yekuona PD uye mamwe maprotocol epamhepo, uye vashandisi vanogona kuona akawanda-protocol kodhi yekuchengetedza uye akasiyana ekuchengetedza tsika mabasa.
Kana zvasvika kune yakakwirira-simba nekukurumidza kuchaja, inongogara isinga patsanurwe kubva kune yakakwirira-chaiyo voltage regulation.RK838 inotsigira anogara ari voltage kubuda kwe3.3-30V, uye inogona kuona inogara iripo rutsigiro rwe0-12A.Kana iyo inogara iripo iri mukati me5A, iko kukanganisa kuri pasi pe ± 50mA.

RK838 zvakare ine yakavakirwa-mukati-yakakwana kuchengetedza mabasa, pakati peiyo CC1/CC2/DP/DM/DP2/DPM2 mapini ese anotsigira 30V anomira nevoltage, iyo inogona kunyatso kudzivirira yakakanganisika mitsara yedata kubva pakukonzera kukuvara kwechigadzirwa, uye kutsigira kuvharika nekukurumidza kwekubuda mushure mekuwandisa. .Iyo chip zvakare ine yakavakirwa-mukati yekudzivirira yekudzivirira, overvoltage kuchengetedzwa, undervoltage kuchengetedzwa uye overheating kudzivirira kuve nechokwadi chekushandiswa kwakachengeteka.
