Kutshanje, i-GigaDevice, umboneleli okhokelayo we-semiconductor kwishishini, usungule i-gd32f403 entsha ye-Gd32f403 Series High-Performance basic microcontroller esekwe kwi-168mhz cortex-m4 core, ebonelela ngexabiso eliphantsi lokungena kwinqanaba lokukhetha kwiimfuno eziphambili zekhompyuter kunye nezixhobo zenkqubo elungeleleneyo kunye nomda. uqwalaselo.Njengelungu lamva nje le-gd32 yosapho lwe-microcontroller, uchungechunge lwe-gd32f403 lubonelela ngeemodeli zemveliso ezingama-20, kubandakanya neentlobo ezine zeepakethe ezibandakanya i-lqfp144, lqfp100, lqfp64 kunye ne-bga100.Ke, inokuhlangabezana ngokulula nemiceli mngeni yokuphuhlisa ngokukhawuleza usetyenziso olukrelekrele kunye nokuguquguquka okugqwesileyo koyilo kunye nokuhambelana.Okwangoku, uluhlu lweemveliso sele luqalile ukubonelela ngeesampuli, kwaye luya kufakwa ngokusemthethweni kwimveliso yobuninzi kunye nokunikezelwa ngokupheleleyo ngoMatshi.
Iimveliso ezintsha ze-GD32F403 zamkela uyilo lwenkqubo entsha, kunye nobuninzi obuninzi beprosesa ukuya kwi-168mhz, kwaye idibanise isethi yomyalelo we-DSP epheleleyo, amandla ekhompyutheni ahambelanayo kunye neyunithi ekhethekileyo yokusebenza kwendawo edadayo (FPU).Ixhotyiswe nge-256Kb ukuya kwi-3072kb umthamo omkhulu weflash kunye ne-64KB ukuya kwi-128KB SRAM.I-kernel ifikelela kwimemori ye-flash ngesantya esiphezulu kunye nokulinda kwe-zero, kwaye ukusebenza komsebenzi phantsi kwe-frequency ephezulu kakhulu kunokufikelela kwi-210dmips kunye ne-coremark ® Uvavanyo lunokufikelela kumanqaku angama-565.Xa kuthelekiswa nokusebenza kakuhle kwekhowudi phantsi kwe-frequency ephambili, iimveliso ze-cortex-m4 ezifanayo kwiimarike ziye zanda nge-10% - 20%, kwaye zigqithise ngokubanzi i-cortex ®-M3 iimveliso, ukuphuculwa komsebenzi ongaphezulu kwe-40%.
I-GD32F403 ye-chip yochungechunge ixhotyiswe ngezibali-xesha ezimbini ze-16 bit ezixhasa isigaba esithathu semveliso ehambelanayo ye-PWM kunye nojongano lokufunyanwa kweholo, olunokusetyenziswa kulawulo lwe-vector.Ikwanayo ukuya kuthi ga kwi-16 bit timers jikelele, ezimbini ze-16 bit timer ezisisiseko kunye nezilawuli ezimbini ze-DMA zamatshaneli amaninzi.Ukuqwalasela iimfuno zezicelo eziphambili, iintlobo zezibonelelo zepheripheral zihlanganiswe ngendlela elinganayo kunye nesebenzayo.Kubandakanya ukuya ku 3 USARTs, 2 UARTS, 3 SPIs, 2 I2C, 2 I2S kunye 2 can2 0b, 1 SDIO, 1 eyakhelwe-ngaphakathi USB 2.0 OTG FS interface, enokubonelela ngeendlela ezininzi zothumelo ezifana isixhobo, host kunye OTG, kwaye ine-oscillator ye-48mhz ezimeleyo ukuxhasa uyilo oluncinci lwekristale.Itshiphu ifakwe ezintathu 12 bit High-Speed ADCs kunye izinga isampuli ukuya ku 2.6msps, ibonelela ukuya kuthi ga kwi-21 amajelo asebenzisekayo, yongeza 16 bit hardware oversampling umsebenzi wokucoca kunye nesisombululo umsebenzi olungisekayo, kwaye kwakhona ezimbini 12 bit DACs.Ukuya kuthi ga kwi-80% ye-GPIO inemisebenzi eyahlukeneyo yokuzikhethela kwaye ixhasa uhlengahlengiso lwezibuko.Inokuguquguquka okugqwesileyo kunye nokulula kokusetyenziswa ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
I-chip ithatha umbane we-2.6v-3.6v, kwaye i-port ye-I / O inokumelana nenqanaba le-5V.Idomeyini yombane esandula ukuyilwa ixhasa ulawulo lwamandla akumgangatho ophezulu kwaye ibonelela ngeendlela ezintathu zokugcina amandla.Owona mbane uphezulu wokusebenza kuzo zonke iiperipherals kwimowudi yokusebenza kwesantya esipheleleyo yi-380 µ A / MHz kuphela, kwaye imo yokulinda xa iqhutywa yibhetri ingaphantsi kwe-1 µ a, eqinisekisa ukusebenza okuphezulu kunye nokufezekisa umlinganiselo wokusetyenziswa kwamandla.Ikwanayo ne-6kV yokhuseleko lombane we-electrostatic (ESD) kunye nezakhono ezigqwesileyo ze-electromagnetic comppatibility (EMC), zonke zihambelana nokuthembeka okuphezulu kweshishini kunye nemigangatho yobushushu.
UJin Guangyi, umphathi omkhulu wentengiso yemveliso yeZhaoyi innovation, uthe, "I-Gd32f403 yenjongo ngokubanzi ye-MCU idibanisa ukusebenza kakuhle kwenkqubo kunye nezixhobo ezilungelelanisiweyo ze-peripheral, ukunceda uyilo olusisiseko kunye nokuphunyezwa kwezicelo eziphambili zekhompyuter kunye nokusetyenziswa kwamandla aphantsi kunye neendleko eziphezulu. Asiyi kuphucula kuphela umgca wemveliso osebenza kakhulu, kodwa siqhubeke nokwandisa kwaye sityebise uluhlu olukhethiweyo lwe-cortex-m4 engundoqo ye-MCU, ukuze abaphuhlisi bakwazi ukwakha ikamva ngokulula ukusetyenziswa kwesiqhelo kunye nexabiso elongeziweyo. amava."
I-GigaDevice ikwaxhotyiswe ngelayibrari ye-firmware epheleleyo kunye netyebileyo yochungechunge olutsha lwemveliso, kunye ne-ecosystem ye-gd32 yophuhliso, kuquka iibhodi zophuhliso ezahlukeneyo kunye nesofthiwe yesicelo, nayo ilungile.Izixhobo ezitsha zophuhliso ziquka i-gd32403z-eval, i-gd32403v-start kunye ne-gd32403r-start, ehambelana nezixhobo zokufunda ezintathu ezineephakheji ezahlukeneyo kunye nezikhonkwane, ezilungele abasebenzisi ukuba baphuhlise kwaye balungise.Ikwabonelela ngolungiso lweempazamo kunye nesixhobo sokuvelisa ngobuninzi ikhonkco le-GD elixhasa imisebenzi emithathu kumsebenzi omnye wokulinganisa kwi-intanethi, ukutshiswa kwi-intanethi kunye nokutshisa ngaphandle kweintanethi.Enkosi kwi-ecosystem yengalo ebanzi, isoftware yophuhliso engaphezulu kunye nezixhobo zokutshisa zomntu wesithathu ezifana ne-keil MDK kunye ne-crossworks nazo zixhaswe ngokupheleleyo.Ezi zenze lula kakhulu ubunzima bophuhliso lweprojekthi kwaye zawukhawulezisa ngokufanelekileyo umjikelo wokuqaliswa kwemveliso.
