Rockchip yakaburitsa chip itsva yeRK838 yekuchaja nekukurumidza, ine kurongeka kwakasimba kwemagetsi, simba rinoshandiswa zvakanyanya panguva imwe chete, uye yakapasa chitupa cheUFCS.

Mashoko Ekutanga

Chip yeprotocol chikamu chakakosha uye chakakosha chechaja. Ine basa rekutaurirana nemudziyo wakabatana, izvo zvakafanana nebhiriji rinobatanidza mudziyo. Kugadzikana kwechip yeprotocol kunoita basa guru muruzivo nekuvimbika kwekuchaja nekukurumidza.

Munguva pfupi yapfuura, Rockchip yakatanga protocol chip RK838 ine Cortex-M0 core yakavakirwa mukati, iyo inotsigira USB-A ne USB-C dual-port fast charging, inotsigira PD3.1, UFCS uye ma protocol akasiyana-siyana ekuchaja fast charging ari pamusika, uye inogona kuita kuti simba rekuchaja repamusoro-soro i240W, inotsigira high-precision constant voltage uye constant current control uye ultra-low standby power consumption.

Rockchip RK838

Rockchip RK838 ipurototi yekuchaja nekukurumidza inobatanidza USB PD3.1 neUFCS protocol core, ine USB-A port neUSB-C port, inotsigira A+C dual output, uye machaneli ese ari maviri anotsigira UFCS protocol. Nhamba yesitifiketi yeUFCS: 0302347160534R0L-UFCS00034.

RK838 inoshandisa magadzirirwo eMCU, inobatanidza mukati meCortex-M0 core, nzvimbo yekuchengetera flash ine simba re56K, nzvimbo ye2K SRAM yekuita PD nedzimwe nzira dzekuchengetedza, uye vashandisi vanogona kuita kuchengetedza kodhi yeprotocol yakawanda uye mabasa akasiyana-siyana ekudzivirira.
Kana zvasvika pakuchaja nekukurumidza zvine simba guru, hazviparadzaniswi kubva pakudzora voltage kwakanyatsonaka. RK838 inotsigira kubuda kwevoltage yakajairika ye3.3-30V, uye inogona kuwana rutsigiro rwakasimba rwe 0-12A. Kana current yakajairika iri mukati me5A, kukanganisa kuri pasi pe ±50mA.

RK838 ine mabasa ekudzivirira akavakirwa mukati, ayo CC1/CC2/DP/DM/DP2/DPM2 pins dzese dzinotsigira 30V inodzivirira voltage, izvo zvinogona kudzivirira zvinobudirira kukuvara kwedata kubva mukukanganisa chigadzirwa, uye zvinotsigira kudzima nekukurumidza kwemagetsi mushure mekupfuura simba. Chip iyi inewo dziviriro yakavakirwa mukati, dziviriro yakawandisa simba, dziviriro yakawandisa simba uye dziviriro yakakwira kupisa kuitira kuve nechokwadi chekushandiswa kwakachengeteka.
