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

Incazelo

I-Atmel® |I-SMART™ SAM R21 iwuchungechunge lwama-microcontrollers anamandla aphansi asebenzisa i-32-bit ARM® Cortex®-M0+ processor kanye ne-transceiver yebhendi ye-ultra-low ehlanganisiwe ye-2.4GHz ISM.Amadivayisi e-SAM R21 atholakala ngamaphakeji angu-32- namaphini angu-48 afinyelela ku-256KB Flash, 32KB we-SRAM futhi asebenza ngefrikhwensi enkulu engu-48MHz futhi afinyelela ku-2.14 Coremark/MHz.Idizayinelwe ukufuduka okulula nokunembile okunamamojula afanayo okuzungeza, ikhodi ehambisanayo ye-hex, imephu yekheli yomugqa ofanayo kanye nezindlela zokufuduka ezihambisanayo nezikhonkwane phakathi kwawo wonke amadivayisi ochungechungeni lomkhiqizo.Wonke amadivaysi ahlanganisa okuphathelene nokuxhumana okuhlakaniphile nokuguquguqukayo, Isistimu Yomcimbi ye-Atmel yokusayinda okuphakathi komngcele, nokusekelwa kwenkinobho yokuthinta i-capacitive, ukuxhumana komsebenzisi kwesilayidi nesondo.Amadivayisi e-Atmel SAM R21 ahlinzeka ngezici ezilandelayo: I-Flash ehlelekayo yangaphakathi nohlelo, isilawuli se-12-channel direct memory access (DMA), i-12-channel Event System, isilawuli esiphazamisayo esihlelekayo, izikhonkwane ze-I/O ezihlelekayo ezingafika ku-28, amandla aphansi kakhulu. I-transceiver yebhendi engu-2.4GHz ISM enenani ledatha elingu-250kB/s, iwashi lesikhathi sangempela elingu-32-bit kanye nekhalenda, ezintathu ze-16-bit Timer/Counters (TC) kanye ne-16-bit Timer/Counters for Control ezintathu (TCC), lapho ngayinye I-TC ingalungiselelwa ukwenza imvamisa kanye nokukhiqiza i-waveform, isikhathi sokwenza uhlelo olunembile noma ukuthwebula okokufaka okuhambisana nesikhathi nesilinganiso samasiginali edijithali.Ama-TC angasebenza ngemodi engu-8- noma engu-16-bit, ama-TC akhethiwe angashintshwa enze i-32-bit TC, kanti I-Timer/Counters for Control ezintathu zinemisebenzi enwetshiwe elungiselelwe injini, ukukhanyisa nezinye izinhlelo zokusebenza zokulawula.Uchungechunge luhlinzeka ngosokhaya oyedwa oshumekwe we-USB 2.0 onesivinini esigcwele kanye nesixhumi esibonakalayo sedivayisi;kufika kuma-Serial Communication Modules amahlanu (SERCOM) ngalinye elingalungiselelwa ukuthi lisebenze njenge-USART, UART, SPI, I2C up 3.4MHz kanye nesigqila se-LIN;kufikela kushaneli eyisishiyagalombili 350ksps 12-bit ADC enenzuzo ehlelekayo kanye nokuzikhethela ngokweqile kwesampula nokuncishiswa okusekela ukulungiswa okufika ku-16-bit, izifanisi ezimbili ze-analog ezinemodi yewindi, I-Peripheral Touch Controller esekela izinkinobho ezifika ku-48, izilayidi, amasondo nokuzwa ukuba seduze;I-Watchdog Timer ehlelekayo, umtshina o-brown-out kanye nokusetha kabusha amandla kanye nohlelo lwamaphini amabili we-Serial Wire Debug (SWD) kanye nesixhumi esibonakalayo sokususa iphutha.
