Rockchip yashyize ahagaragara chip nshya ya protocole yo gusharija vuba RK838, ifite ubushobozi bwo gukoresha ingufu zihoraho cyane, ikoresha ingufu nke cyane, kandi yemerewe na UFCS.

Ijambo ry'ibanze

Chipu ya protocole ni igice cy'ingenzi kandi cy'ingenzi cy'iyi charger. Ishinzwe kuvugana n'igikoresho gihujwe, bingana n'ikiraro gihuza igikoresho. Gukomera kwa chip ya protocole bigira uruhare runini mu bunararibonye no mu kwizerwa mu gusharija vuba.

Mu minsi ishize, Rockchip yashyize ahagaragara chip ya protocole RK838 ifite core ya Cortex-M0 yubatswemo, ishyigikira gusharija vuba kuri USB-A na USB-C, ishyigikira PD3.1, UFCS n'izindi protocole zitandukanye zo kwihutisha gusharija ku isoko, kandi ishobora gukora. Ingufu zo kwihutisha gusharija nyinshi ni 240W, ishyigikira voltage ihoraho yo hejuru n'igenzura ry'umuyoboro uhoraho hamwe n'ikoreshwa ry'amashanyarazi make cyane.

Rockchip RK838

Rockchip RK838 ni chip ya protocole yo kwihutisha ihuza USB PD3.1 na protocole ya UFCS, ifite porte ya USB-A na porte ya USB-C, ishyigikira A+C dual output, kandi channels zombi zishyigikira protocole ya UFCS. Nimero ya seritifika ya UFCS: 0302347160534R0L-UFCS00034.

RK838 ikoresha imiterere ya MCU, ihuza imbere Cortex-M0 core, ububiko bwa flash bwa 56K nini, ububiko bwa SRAM bwa 2K kugira ngo ikore PD n'izindi porotolike zihariye, kandi abakoresha bashobora gukora ububiko bwa kode nyinshi hamwe n'imikorere itandukanye yo kurinda.
Ku bijyanye no gushyushya vuba cyane, ntabwo bitandukaniye n'amabwiriza y'amashanyarazi ahamye. RK838 ishyigikira ingufu zihoraho zo gusohora 3.3-30V, kandi ishobora gutanga ingufu zihoraho zo gushyigikirwa na 0-12A. Iyo ingufu zihoraho ziri muri 5A, ikosa riba riri munsi ya ±50mA.

RK838 ifite kandi imikorere y’uburinzi yuzuye, muri yo CC1/CC2/DP/DM/DP2/DPM2 pin zose zishyigikira 30V zihanganira voltage, zishobora gukumira neza imirongo y’amakuru yangiritse kwangiza ibicuruzwa, kandi zigashyigikira kuzimya vuba umusaruro nyuma yo gusohora voltage nyinshi. Iyi chip ifite kandi uburinzi bw’amashanyarazi menshi, uburinzi bw’amashanyarazi menshi, uburinzi bw’amashanyarazi make no kurinda gushyuha cyane kugira ngo ikoreshwe neza.
