GigaDevic cortex-m4 MCU yongeyeho gd32f403

GD32F403 yuruhererekane rwibicuruzwa bishya byemeza uburyo bushya bwo gutunganya, hamwe ninshuro ntarengwa yiganjemo gutunganya kugeza kuri 168mhz, kandi igahuza amabwiriza yuzuye ya DSP, igereranya imbaraga zo kubara hamwe nigice cyihariye cyo kureremba (FPU).Ifite ibikoresho 256Kb kugeza 3072kb nini nini ya flash na 64KB kugeza 128KB SRAM.Intangiriro igera kuri flash yibuka ifite umuvuduko mwinshi na zeru gutegereza, kandi imikorere yakazi munsi yumurongo wiganje irashobora kugera kuri 210dmips na coremark ® Ikizamini gishobora kugera kumanota 565.Ugereranije na code ikora neza mugihe gikuru, ibicuruzwa bisa na cortex-m4 kumasoko byiyongereyeho 10% - 20%, kandi byarenze byose ibicuruzwa bya cortex ®- M3, kuzamura imikorere irenga 40%.

Chip ya seriveri ya GD32F403 ifite ibikoresho bibiri 16 bito bigezweho byunganira ibyiciro bitatu byuzuzanya bya PWM hamwe nuburyo bwo kugura salle, bishobora gukoreshwa mugucunga ibice.Ifite kandi ibihe bigera ku munani 16 biti rusange, bibiri 16 bito byibanze hamwe na bibiri bya DMA bigenzura.Urebye ibisabwa bya porogaramu zateye imbere, ibikoresho bitandukanye bya peripheri byahujwe muburyo bwiza kandi bufatika.Harimo USARTs zigera kuri 3, 2 UARTS, 3 SPIs, 2 I2C, 2 I2S na 2 can2 0b, 1 SDIO, 1 yubatswe muri USB 2.0 OTG FS, ishobora gutanga uburyo bwinshi bwo kohereza nkibikoresho, host na OTG, na ifite oscillator yigenga 48mhz kugirango ishyigikire kristu nkeya.Chip ifite ibikoresho bitatu 12 12 Byihuta-byihuta bya ADC hamwe nigipimo cyikigereranyo kigera kuri 2.6msps, gitanga imiyoboro igera kuri 21 yongeye gukoreshwa, ikongeramo 16 biti ibyuma birenga ibikoresho byo kuyungurura no gukemura, kandi ikagira na DAC ebyiri 12.Kugera kuri 80% ya GPIO ifite ibikorwa bitandukanye byubushake kandi ishyigikira gusubiramo ibyambu.Ifite imiterere ihindagurika kandi yoroshye yo gukoresha kugirango ihuze ibyifuzo bitandukanye.

Chip ifata amashanyarazi 2.6v-3.6v, kandi icyambu cya I / O gishobora kwihanganira urwego 5V.Umuyoboro mushya wa voltage ushyigikira imiyoborere igezweho kandi itanga uburyo butatu bwo kuzigama ingufu.Umubare ntarengwa wakazi wa periferique zose muburyo bwihuse bwo gukora ni 380 µ A / MHz, kandi umuyoboro uhagaze iyo ukoresheje bateri uri munsi ya 1 µ a, ibyo bigatuma ukora neza kandi ukagera ku kigereranyo cyiza cyo gukoresha ingufu.Ifite kandi 6kV irinda amashanyarazi (ESD) hamwe nubushobozi buhebuje bwa electromagnetic ihuza (EMC), byose bijyanye ninganda zizewe cyane hamwe nubushyuhe bwubushyuhe.

Jin Guangyi, umuyobozi mukuru ushinzwe kwamamaza ibicuruzwa muri Zhaoyi guhanga udushya, yagize ati: "Gd32f403 ikurikirana rusange-intego rusange MCU ihuza uburyo bunoze bwo gutunganya no gutunganya umutungo wa peripheri, kugira ngo ifashe igishushanyo mbonera n’ishyirwa mu bikorwa rya porogaramu zigezweho zo kubara hakoreshejwe ingufu nke kandi zikoresha amafaranga menshi. Ntabwo tuzakomeza kunoza imikorere yumurongo wo hejuru cyane, ahubwo tuzakomeza kwagura no gutezimbere urwego rwo guhitamo cortex-m4 yibanze ya MCU, kugirango abitezimbere bashobore kubaka ejo hazaza byoroshye-gukoresha-byoroshye kandi byongerewe agaciro. uburambe. "

GigaDevice ifite kandi isomero ryuzuye kandi rikungahaye ryibitabo byububiko bwibicuruzwa bishya, kandi urusobe rwibidukikije rwa gd32, harimo imbaho ​​zitandukanye ziterambere hamwe na software ikoreshwa, nabyo biriteguye.Ibikoresho bishya byiterambere birimo gd32403z-eval, gd32403v-gutangira na gd32403r-gutangira, bihuye nibikoresho bitatu byo kwiga bifite paki na pin zitandukanye, byorohereza abakoresha kwiteza imbere no kubikemura.Itanga kandi ibikoresho byo gukemura no gukora byinshi GD ihuza ishyigikira bitatu mumikorere imwe yo kwigana kumurongo, gutwika kumurongo no gutwika kumurongo.Turabikesha urusobe rwibinyabuzima rwagutse, software nyinshi ziterambere hamwe nibikoresho bya gatatu byo gutwika nka keil MDK hamwe na crossworks nabyo byashyigikiwe byimazeyo.Ibi byoroheje cyane ingorane ziterambere ryumushinga kandi byihutisha neza ibicuruzwa byo gutangiza ibicuruzwa.
