Kev piav qhia

Atmel® |SMART ™ SAM R21 yog cov khoom siv hluav taws xob qis qis siv 32-ntsis ARM® Cortex®-M0+ processor thiab kev sib xyaw ua ke ultra-low zog 2.4GHz ISM band transceiver.SAM R21 cov khoom siv muaj nyob rau hauv 32- thiab 48-pin pob khoom nrog txog 256KB Flash, 32KB ntawm SRAM thiab ua haujlwm ntawm qhov siab tshaj plaws ntawm 48MHz thiab ncav cuag 2.14 Coremark / MHz.Lawv yog tsim los rau kev yooj yim thiab intuitive tsiv teb tsaws nrog zoo tib yam peripheral modules, hex tshaj code, zoo tib yam linear chaw nyob daim ntawv qhia thiab tus pin tau tshaj migration paths ntawm tag nrho cov pab kiag li lawm nyob rau hauv cov khoom series.Tag nrho cov khoom siv suav nrog cov khoom siv ntse thiab hloov tau yooj yim, Atmel Event System rau kev taw qhia kev sib txuas, thiab kev txhawb nqa rau lub khawm kov capacitive, slider thiab log neeg siv interfaces.Cov khoom siv Atmel SAM R21 muab cov yam ntxwv hauv qab no: Hauv-system programmable Flash, 12-channel ncaj qha kev nco nkag (DMA) maub los, 12-channel Event System, programmable interrupt controller, mus txog 28 programmable I/O pins, ultra-low zog 2.4GHz ISM band transceiver nrog cov ntaub ntawv tus nqi ntawm 250kB / s, 32-ntsis real-time moos thiab daim ntawv qhia hnub, peb 16-ntsis Timer / Counters (TC) thiab peb 16-ntsis Timer / Counters rau Tswj (TCC), qhov twg txhua TC tuaj yeem raug teeb tsa los ua qhov zaus thiab waveform tiam, kev ua haujlwm raug raws sijhawm lossis kev nkag mus ntes nrog lub sijhawm thiab zaus ntsuas ntawm cov cim digital.TCs tuaj yeem ua haujlwm nyob rau hauv 8- lossis 16-ntsis hom, xaiv TCs tuaj yeem ua haujlwm los ua 32-ntsis TC, thiab peb lub Timer / Counters rau Tswj tau txuas ntxiv ua haujlwm tau zoo rau lub cev muaj zog, teeb pom kev zoo thiab lwm yam kev tswj xyuas.Cov koob muab ib qho kev ceev USB 2.0 embedded host thiab ntaus ntawv interface;mus txog tsib Serial Communication Modules (SERCOM) uas txhua tus tuaj yeem teeb tsa los ua tus USART, UART, SPI, I2C txog 3.4MHz thiab LIN qhev;mus txog yim channel 350ksps 12-ntsis ADC nrog cov programmable nce thiab kev xaiv oversampling thiab decimation txhawb nqa txog 16-ntsis daws teeb meem, ob qho piv txwv analog nrog lub qhov rais hom, Peripheral Touch Controller txhawb nqa txog 48 nyees khawm, sliders, log thiab qhov sib thooj sensing;programmable Watchdog Timer, xim av-tawm ntes thiab rov pib dua lub zog thiab ob-pin Serial Wire Debug (SWD) program thiab debug interface.
