Ibisobanuro

Atmel® |SmartIbikoresho bya SAM R21 biraboneka mubipaki 32- na 48-pin hamwe na Flash igera kuri 256KB, 32KB ya SRAM kandi ikora kumurongo ntarengwa wa 48MHz kandi igera kuri 2.14 Coremark / MHz.Byashizweho kubwimuka bworoshye kandi bwimbitse hamwe na moderi imwe ya periferique, kode ihujwe, ikarita ihuza aderesi imwe hamwe ninzira yo kwimuka ihuza ibikoresho byose murutonde rwibicuruzwa.Ibikoresho byose birimo ubwenge kandi bworoshye periferique, Sisitemu ya Atmel yo kwerekana ibimenyetso hagati ya periferique, hamwe ninkunga ya capacitive touch bouton, slide na interineti ukoresha interineti.Ibikoresho bya Atmel SAM R21 bitanga ibintu bikurikira: Muri sisitemu ishobora gutegurwa na Flash, imiyoboro 12 yububiko butaziguye (DMA) umugenzuzi, imiyoboro 12 yibikorwa, gahunda yo guhagarika porogaramu, kugeza kuri 28 porogaramu I / O ishobora gukoreshwa, imbaraga zidasanzwe 2.4GHz ISM band transceiver hamwe nigipimo cyamakuru ya 250kB / s, 32-bit-isaha nyayo-isaha na kalendari, bitatu-16-biti bya Timer / Counters (TC) na bitatu-16-biti ya Timer / Counters for Control (TCC), aho buri TC irashobora gushyirwaho kugirango ikore inshuro nyinshi hamwe na flimform ya generation, gahunda nyayo yo gukora igihe cyangwa kwinjiza kwinjiza hamwe nigihe cyo gupima ibimenyetso bya digitale.TC irashobora gukora muburyo bwa 8- cyangwa 16-bit, TC yatoranijwe irashobora gutondekwa kugirango ikore TC 32-bit, kandi bitatu bya Timer / Counters for Control byongereye imikorere itezimbere moteri, amatara nibindi bikorwa byo kugenzura.Urukurikirane rutanga umuvuduko wuzuye USB 2.0 yashyizwemo host hamwe nibikoresho bya interineti;bigera kuri bitanu byitumanaho byitumanaho (SERCOM) buri kimwe gishobora gushyirwaho kugirango gikore nka USART, UART, SPI, I2C hejuru ya 3.4MHz na LIN imbata;imiyoboro igera kuri umunani 350ksps 12-biti ya ADC hamwe ninyungu zishobora gutegurwa hamwe nubushake burenze urugero hamwe na decimation ishyigikira ibisubizo bigera kuri 16-bit, kugereranya bibiri bigereranya nuburyo bwidirishya, Peripheral Touch Controller ishyigikira buto zigera kuri 48, ibitonyanga, ibiziga hamwe no kumva hafi;programable Watchdog Timer, detector yubururu hamwe na power-on reset hamwe na pin-ebyiri Serial Wire Debug (SWD) hamwe na interineti yo gukemura.
