GigaDevic cortex-m4 MCU imawonjezera mndandanda wa gd32f403

Zogulitsa zatsopano za GD32F403 zimatengera kamangidwe katsopano, kokhala ndi ma frequency apamwamba kwambiri a purosesa mpaka 168mhz, ndikuphatikiza dongosolo lathunthu la malangizo a DSP, mphamvu zamakompyuta zofananira ndi gawo lapadera loyandama (FPU).Ili ndi 256Kb mpaka 3072kb mphamvu yayikulu yowunikira ndi 64KB mpaka 128KB SRAM.Kernel imafikira kukumbukira kwa flash ndi liwiro lalikulu ndi zero kudikirira, ndipo ntchito yogwira ntchito pansi pa maulendo apamwamba kwambiri imatha kufika 210dmips ndi coremark ® Mayeso amatha kufika pa 565 mfundo.Poyerekeza ndi kaphatikizidwe ka code pansi pa ma frequency akulu, zinthu zofananira za cortex-m4 pamsika zawonjezeka ndi 10% - 20%, ndipo zapambana kwambiri kuposa zinthu za cortex ®- M3, kusintha kwa magwiridwe antchito kuposa 40%.

Chip cha GD32F403 chili ndi zowerengera ziwiri zapamwamba 16 zomwe zimathandizira magawo atatu a PWM ndi mawonekedwe ogulira holo, omwe angagwiritsidwe ntchito kuwongolera vekitala.Ilinso ndi zowerengera nthawi zisanu ndi zitatu za 16 bit, ziwiri zoyambira 16 ndi zowongolera ma DMA amitundu yambiri.Poganizira zofunikira zamapulogalamu apamwamba, zida zosiyanasiyana zozungulira zimaphatikizidwa moyenera komanso moyenera.Kuphatikiza mpaka 3 UARTS, 2 UARTS, 3 SPIs, 2 I2C, 2 I2S ndi 2 can2 0b, 1 SDIO, 1 yomangidwa mkati USB 2.0 OTG FS mawonekedwe, omwe angapereke njira zingapo zotumizira monga chipangizo, host ndi OTG, ndi ili ndi oscillator yodziyimira payokha ya 48mhz kuti ithandizire kupanga kocheperako.Chipchi chili ndi ma ADC atatu a 12-bit High-Speed ​​​​Speed ​​​​ndi mlingo wa sampuli mpaka 2.6msps, amapereka mpaka 21 njira zogwiritsira ntchito, kuwonjezera 16 bit hardware oversampling ntchito ndi kusamvana configurable, komanso ili ndi awiri 12 pang'ono DACs.Mpaka 80% ya GPIO ili ndi ntchito zosiyanasiyana zomwe mungasankhe ndipo imathandizira kukonzanso madoko.Ili ndi kusinthasintha kwabwino komanso kosavuta kugwiritsa ntchito kuti ikwaniritse zofunikira zosiyanasiyana.

Chip chimagwiritsa ntchito magetsi a 2.6v-3.6v, ndipo doko la I / O limatha kupirira mulingo wa 5V.Domeni yamagetsi yomwe yangopangidwa kumene imathandizira kasamalidwe kamphamvu kapamwamba komanso imapereka njira zitatu zopulumutsira mphamvu.Kuchuluka kwazomwe zimagwira ntchito pamachitidwe onse othamanga ndi 380 µ A / MHz okha, ndipo zoyimilira zomwe zimayendetsedwa ndi batire ndizochepera 1 µ a, zomwe zimatsimikizira magwiridwe antchito apamwamba ndikukwaniritsa chiyerekezo chabwino kwambiri chamagetsi.Ilinso ndi 6kV electrostatic protection (ESD) ndi kuthekera kwabwino kwa electromagnetic compatibility (EMC), zonse zikugwirizana ndi kudalirika kwakukulu kwa mafakitale ndi miyezo ya kutentha.

Jin Guangyi, wamkulu wogulitsa malonda a Zhaoyi innovation, adati, "MCU ya Gd32f403 mndandanda wa cholinga chachikulu cha MCU imagwirizanitsa mphamvu zogwirira ntchito bwino komanso zogwiritsidwa ntchito moyenera, kuti zithandize kupanga ndi kukhazikitsa mapulogalamu apamwamba a makompyuta omwe amagwiritsa ntchito mphamvu zochepa komanso mtengo wapamwamba. Sitidzangopititsa patsogolo mzere wazinthu zogwira ntchito kwambiri, komanso pitirizani kukulitsa ndi kulemeretsa mitundu yosankhidwa ya cortex-m4 core MCU, kotero kuti otukula athe kupanga tsogolo ndi zosavuta kugwiritsa ntchito komanso zowonjezera mtengo. chidziwitso."

GigaDevice ilinso ndi laibulale yathunthu komanso yolemera ya firmware ya mndandanda watsopano wazogulitsa, ndipo gd32 development ecosystem, kuphatikiza ma board osiyanasiyana achitukuko ndi mapulogalamu ogwiritsira ntchito, nawonso ali okonzeka.Zida zatsopano zachitukuko zikuphatikiza gd32403z-eval, gd32403v-start ndi gd32403r-start, zomwe zimagwirizana ndi zida zitatu zophunzirira zomwe zili ndi mapaketi ndi mapini osiyanasiyana, omwe ndi osavuta kwa ogwiritsa ntchito kupanga ndikuwongolera.Limaperekanso chida chowongolera ndi kupanga misala GD ulalo womwe umathandizira ntchito zitatuzimodzi zoyeserera pa intaneti, kuwotcha pa intaneti ndi kuwotcha osalumikizidwa.Chifukwa cha dongosolo lazachilengedwe la mkono, mapulogalamu ambiri otukuka komanso zida zowotcha za gulu lachitatu monga keil MDK ndi crossworks zathandizidwanso mokwanira.Izi zafewetsa kwambiri zovuta za chitukuko cha polojekiti ndikufulumizitsa bwino ntchito yoyambitsa malonda.
