ATSAMR21G18A-MU IC RF TxRx + MCU Jikelele ISM > 1GHz – 2.4GHz 48-VFQFN Exposed Pad

Inkcazo

I-Atmel® |I-SMART™ SAM R21 luluhlu lwezilawuli ezincinci zamandla asezantsi ezisebenzisa i-32-bit ye-ARM® Cortex®-M0+ iprosesa kunye ne-ultra-low power edibeneyo ye-2.4GHz ISM band transceiver.Izixhobo ze-SAM R21 zifumaneka kwiipakethi ze-32- kunye ne-48-pin ukuya kuthi ga kwi-256KB Flash, 32KB ye-SRAM kwaye zisebenza kwi-frequency ephezulu ye-48MHz kwaye ifike kwi-2.14 Coremark / MHz.Ziyilelwe ukufuduka okulula kunye nokubonakalayo kunye neemodyuli zeperipheral ezifanayo, ikhowudi ye-hex ehambelanayo, imephu yedilesi efanayo kunye neepini ezihambelana neendlela zokufuduka phakathi kwazo zonke izixhobo ezikuluhlu lwemveliso.Zonke izixhobo ziquka i-peripherals ehlakaniphile kunye ne-flexible, i-Atmel Event System ye-inter-peripheral signaling, kunye nenkxaso ye-capacitive touch button, i-slider kunye ne-wheel interfaces yomsebenzisi.Izixhobo ze-Atmel SAM R21 zibonelela ngezi mpawu zilandelayo: I-Flash ecwangcisiweyo ye-In-system, isilawuli se-12-channel yokufikelela ngokuthe ngqo kwimemori (DMA), i-12-channel Event System, isilawuli esiphazamisayo esicwangcisiweyo, ukuya kwii-28 ​​ezicwangcisiweyo ze-I / O izikhonkwane, amandla aphantsi kakhulu. I-2.4GHz ISM band transceiver enezinga ledatha ye-250kB/s, i-32-bit-time-clock-clock kunye nekhalenda, ezintathu ze-16-bit Timer/Counters (TC) kunye ne-16-bit Timer/Counters for Control (TCC), apho nganye I-TC inokumiselwa ukuba yenze i-frequency kunye ne-waveform ukuveliswa, ixesha lokwenziwa kwenkqubo echanekileyo okanye igalelo lokubamba kunye nexesha kunye nomlinganiselo wokuphindaphinda kweempawu zedijithali.I-TCs inokusebenza kwi-8- okanye i-16-bit mode, ii-TC ezikhethiweyo zinokuthi zenziwe i-cascade ukuze zenze i-32-bit TC, kunye ne-Timer / Counters ezintathu zoLawulo zinemisebenzi eyandisiweyo elungiselelwe i-motor, ukukhanya kunye nezinye iinkqubo zokulawula.Olu chungechunge lubonelela nge-speed-speed USB 2.0 host host kunye nojongano lwesixhobo;ukuya kuthi ga kwiiModyuli zoNxibelelwano oluHlanu (SERCOM) ukuba nganye inokumiselwa ukuba isebenze njenge-USART, UART, SPI, I2C up 3.4MHz kunye ne-LIN ikhoboka;ukuya kuthi ga kwishaneli ezisibhozo 350ksps 12-bit ADC ngenzuzo programmable kunye nokuzikhethela oversampling kunye decimation ukuxhasa ukuya kwi-16-bit isisombululo, abathelekisi ezimbini analog kunye imo yefestile, Peripheral Touch Controller ukuxhasa amaqhosha 48, izilayidi, amavili kunye nokuqonda ukusondela;programmable Watchdog Timer, brown-out detector kunye namandla-on reset kunye-pin ezimbini Uthotho Wire Debug (SWD) inkqubo kunye nojongano debug.
