ATSAMD21J18A-AU IC MCU 32BIT 256KB FLASH 64TQFP

Ibisobanuro

SAM D21 / DA1 nuruhererekane rwa microcontrollers ikoresha ingufu nkeya ukoresheje 32-biti ya Arm® Cortex®-M0 + itunganya, kandi kuva kuri 32-pin kugeza kuri 64-pin hamwe na Flash ya 256 KB na 32 KB ya SRAM.SAM D21 / DA1 ikora kuri frequence ntarengwa ya 48 MHz kandi igera kuri 2.46 CoreMark / MHz.Byashizweho kubwimuka bworoshye kandi bwimbitse hamwe na moderi imwe ya periferique, kode ihujwe na kode, ikarita yerekana aderesi imwe, hamwe na pin ihuza inzira yimuka hagati yibikoresho byose murutonde rwibicuruzwa.Ibikoresho byose birimo ubwenge kandi bworoshye periferiya, Sisitemu y'ibyabaye kuri signal-inter-periferique, hamwe n'inkunga ya capacitive touch buto, slide, hamwe nintera yimikoreshereze yimodoka.SAM D21 / DA1 itanga ibintu bikurikira: Muri sisitemu ya porogaramu ishobora gukoreshwa, Imiyoboro 12-ya Direct Memory Access Controller (DMAC), Imiyoboro 12 y'ibyabaye, Sisitemu yo guhagarika porogaramu, igera kuri 52 ishobora gutegurwa I / O, 32-bit Real -Igihe cyamasaha na Kalendari (RTC), bigera kuri bitanu 16-biti ya Timer / Counters (TC) hamwe na bine 24-biti ya Timer / Counters for Control (TCC), aho buri TC ishobora gushyirwaho kugirango ikore inshuro nyinshi kandi izunguruka, gahunda nyayo yo gukora igihe cyangwa kwinjiza gufata hamwe nigihe cyo gupima ibimenyetso bya digitale.TCs irashobora gukora muburyo bwa 8-bit cyangwa 16-bit, TC yatoranijwe irashobora gutondekwa kugirango ikore 32-bit TC, kandi timer / compte eshatu zongereye imikorere itezimbere moteri, itara, nibindi bikorwa byo kugenzura.Urukurikirane rutanga USB yihuta ya USB 2.0 yashyizwemo host hamwe nibikoresho bya interineti;kugeza kuri esheshatu zitumanaho zikurikirana (SERCOM) buriwese ashobora gushyirwaho kugirango akore nka USART, UART, SPI, I2C kugeza kuri 3.4 MHz, SMBus, PMBus, na LIN umukiriya;imiyoboro ibiri I 2S Imigaragarire;kugeza kumurongo wa makumyabiri-350 350 ksps 12-biti ADC hamwe ninyungu zishobora gutegurwa hamwe nubushake burenze urugero hamwe na decimation bishyigikira bigera kuri 16-bit, imwe ya 10-bit 350 ksps DAC, abagereranya bane bagereranya nuburyo bwa Window, Peripheral Touch Controller (PTG) gushyigikira buto zigera kuri 256, ibitonyanga, ibiziga, hamwe no kumva hafi;Porogaramu ishobora gukurikiranwa na Watchdog Timer (WDT), detector yubururu hamwe na power-on Reset hamwe na pin-ebyiri za Serial Wire Debug (SWD) hamwe ninteruro yo gukemura.Ibikoresho byose bifite imbaraga nimbaraga nke zo hanze ninyuma oscillator.Ibinyeganyega byose birashobora gukoreshwa nkisoko yisaha ya sisitemu.Imiterere itandukanye yisaha irashobora gushyirwaho yigenga kugirango ikore kuri radiyo zitandukanye, igushoboza kuzigama ingufu ukoresheje buri periferique kumasaha yayo meza, bityo bikagumana umuvuduko mwinshi wa CPU mugihe ugabanya ingufu zikoreshwa.
