Cov USB interface voltage ntau npaum li cas no?

USB interface voltage yog 5.0V, cov yuav tsum tau tam sim no yuav tsis ntau tshaj li 500ma. Ua tau hwj huam no tsuas siv rau tshaj 2.5W ntawm.

1, VCC
C = Circuit Court nruab nrab yog cov Circuit Court txhais tau hais tias tus voltage ntaub ntawv Circuit Court, nyob rau ib qho hauv Circuit Court, VCC yog cov mov voltage Circuit Court
CadenceVirtual tivthaiv nqi tsim, hu ua VCC, nws yog thawj tsim tus IP rov qab siv lub qhov muaj zog duas HW / SW puag tsim platform ib puag ncig txoj kev loj hlob. Cadence VCC enables designers ntxov nyob rau cov qauv siv los ntawm lub cim ua ntej cov tshuaj thiab lwm yam khoom, koj yuav nrhiav tau cov HW / SW partitioning architecture tseem ceeb heev. Cadence VCC mov cia los ntawm kev sib txuas lus hauv thiab pauv tsim ntaub ntawv, muab lub moj khaum tsim nyog qhov uas qiv thiab SOC.

2, GND
USB interface voltage
GND (av) 1. Circuit Court kos duab thiab Circuit Court board hauv pem teb los rau ntawm kab 0. GND no qab hau, yuav tau hais kom muaj, tiam sis qhov no yuav tsis tau kev rau cov kev txiav txim zoo tiag. Tawm hauv ib daim ntawv hypothetical, kev muaj hwj huam, nws yog lub zog tsis zoo mov. Nws yog txawv nrog lub ntiaj teb. Tej zaum nws yuav tsum tau txuas nrog lub ntiaj teb, thiab tej zaum yuav tsis tau, nyob ntawm lub cev, raws li qhov muaj tshwm sim.
2. USB rau ntawm: VCC yog txoj kev hwj huam; GND av; DP, DM yog lub teeb liab plawg; -Chaw nres NKOJ, chaw nres NKOJ + ntaub ntawv tam sim no, ib tug zoo co tes.
