I-GigaDevic cortex-m4 MCU ingeza uchungechunge lwe-gd32f403

Uchungechunge lwemikhiqizo emisha ye-GD32F403 yamukela idizayini yenqubo entsha, enefrikhwensi ephezulu ebusayo yephrosesa efika ku-168mhz, futhi ihlanganisa isethi yemiyalo ye-DSP ephelele, amandla ekhompuyutha ahambisanayo kanye neyunithi yokusebenza yephoyinti elintantayo elikhethekile (i-FPU).Ifakwe 256Kb kuya ku-3072kb umthamo omkhulu weflash kanye no-64KB kuya ku-128KB SRAM.I-kernel ifinyelela inkumbulo ye-flash ngesivinini esikhulu nokulinda okungu-zero, futhi ukusebenza ngaphansi kwefrikhwensi ephezulu kakhulu kungafinyelela ku-210dmips kanye ne-coremark ® Ukuhlolwa kungafinyelela amaphuzu angu-565.Uma kuqhathaniswa nokusebenza kahle kwekhodi ngaphansi kwemvamisa eyinhloko, imikhiqizo efanayo ye-cortex-m4 emakethe inyuke ngo-10% - 20%, futhi iye yadlula ngokuphelele imikhiqizo ye-cortex ®- M3, ukuthuthukiswa kokusebenza okungaphezu kuka-40%.

I-chip ye-GD32F403 yochungechunge ifakwe izibali sikhathi ezimbili ezithuthukisiwe eziyi-16 ezisekela okukhiphayo okuhambisanayo kwezigaba ezintathu ze-PWM kanye nesixhumi esibonakalayo sokutholwa kwehholo, esingasetshenziselwa ukulawula i-vector.Iphinde ibe nezibali-sikhathi ezijwayelekile eziyisishiyagalombili ze-16 bit, izibali-sikhathi eziyisisekelo ezingu-16 bit kanye nezilawuli ezimbili ze-DMA ezineziteshi eziningi.Ngokucabangela izidingo zezicelo ezithuthukisiwe, izinsiza ezihlukahlukene ze-peripheral zihlanganiswa ngendlela elinganiselayo nesebenzayo.Kubandakanya ama-USART angu-3, ​​2 UARTS, 3 SPIs, 2 I2C, 2 I2S kanye 2 can2 0b, 1 SDIO, 1 eyakhelwe ngaphakathi USB 2.0 OTG FS interface, enganikeza izindlela eziningi zokudlulisela njengedivayisi, umsingathi kanye ne-OTG, kanye ine-oscillator ezimele engu-48mhz ukuze isekele ukwakheka okuncane kwekristalu.I-chip ifakwe ama-ADC amathathu we-12 bit High-Speed ​​anesilinganiso sesampula esifika ku-2.6msps, ihlinzeka ngamashaneli angasetshenziswa kabusha angama-21, yengeza umsebenzi wokuhlunga we-16 bit hardware oversampling nomsebenzi olungisekayo, futhi inama-DAC amabili ayi-12 bit.Kufika ku-80% we-GPIO inemisebenzi ehlukahlukene ongakhetha kuyo futhi isekela ukuklanywa kabusha kwembobo.Inokuguquguquka okuhle kakhulu futhi kulula ukuyisebenzisa ukuze ihlangabezane nezidingo ezahlukahlukene zohlelo lokusebenza.

I-chip isebenzisa ugesi ongu-2.6v-3.6v, futhi imbobo ye-I/O ingakwazi ukumelana neleveli engu-5V.Isizinda se-voltage esisanda kwakhiwa sisekela ukuphathwa kwamandla okuthuthukile futhi sinikeza izindlela ezintathu zokonga amandla.Ubuningi bamanje bokusebenza bawo wonke ama-peripherals kumodi yokusebenza kwesivinini esigcwele ngu-380 µ A / MHz kuphela, futhi okwamanje okulindile uma kunikwe amandla ibhethri kungaphansi kuka-1 µ a, okuqinisekisa ukusebenza okuphezulu futhi kuzuzwe isilinganiso esingcono kakhulu sokusetshenziswa kwamandla.Iphinde ibe nokuvikelwa kwe-electrostatic engu-6kV (ESD) kanye nekhono elihle kakhulu le-electromagnetic comppatibility (EMC), konke okuhambisana nokuthembeka okuphezulu kwezimboni kanye namazinga okushisa.

U-Jin Guangyi, umphathi omkhulu wokumaketha umkhiqizo we-Zhaoyi innovation, uthe, "I-MCU ye-Gd32f403 yochungechunge olujwayelekile ihlanganisa ukusebenza kahle kokucubungula okunamandla kanye nezinsiza ezizungezile, ukuze isize ukwakheka okuyisisekelo kanye nokuqaliswa kwezinhlelo zokusebenza zekhompuyutha ezithuthukisiwe ngokusetshenziswa kahle kwamandla okuphansi kanye nezindleko eziphezulu. ukusebenza. Ngeke nje sithuthukise ulayini womkhiqizo osebenza kahle kakhulu, kodwa futhi sizoqhubeka nokukhulisa nokucebisa uhla lokukhetha lwe-cortex-m4 core MCU, ukuze abathuthukisi bakwazi ukwakha ikusasa ngokusetshenziswa okulula okujwayelekile kanye nenani elingeziwe. isipiliyoni."

I-GigaDevice iphinde ifakwe umtapo wezincwadi we-firmware ophelele futhi ocebile wochungechunge lomkhiqizo omusha, kanye ne-ecosystem yokuthuthukiswa kwe-gd32, okuhlanganisa amabhodi okuthuthukisa ahlukahlukene kanye nesofthiwe yohlelo lokusebenza, nayo isilungile.Amathuluzi amasha okuthuthukisa ahlanganisa i-gd32403z-eval, gd32403v-start kanye ne-gd32403r-start, ehambisana namakhithi okufunda amathathu anamaphakheji ahlukene namaphinikhodi, alungele abasebenzisi ukuwathuthukisa futhi bawalungise.Iphinde inikeze isixhumanisi se-GD sokulungisa iphutha nesokukhiqiza ngobuningi esisekela imisebenzi emithathu kokukodwa kokulingisa okuku-inthanethi, ukushiswa ku-inthanethi kanye nokushiswa ungaxhunyiwe ku-inthanethi.Ngenxa ye-ecosystem ebanzi yengalo, isofthiwe yokuthuthukisa eyengeziwe kanye namathuluzi ashiswayo enkampani yangaphandle njenge-keil MDK nama-crossworks nawo asekelwe ngokugcwele.Lokhu kwenze kwaba lula kakhulu ubunzima bokuthuthukiswa kwephrojekthi futhi kwasheshisa ngempumelelo umjikelezo wokwethulwa komkhiqizo.
