I-ATSAMD21E18A-MU IC MCU 32BIT 256KB FLASH 32QFN

Incazelo

I-SAM D21/DA1 iwuchungechunge lwama-microcontrollers anamandla aphansi asebenzisa i-32-bit Arm® Cortex®-M0+ processor, futhi asukela ku-32-pins kuya ku-64-pins afinyelela ku-256 KB Flash kanye no-32 KB we-SRAM.I-SAM D21/DA1 isebenza ngefrikhwensi enkulu engu-48 MHz futhi ifinyelela ku-2.46 CoreMark/MHz.Idizayinelwe ukufuduka okulula nokunembile okunamamojula afanayo okuzungeza, ikhodi ehambisanayo ye-hex, imephu yekheli yomugqa ofanayo, kanye nezindlela zokufuduka ezihambisanayo ezihambisanayo phakathi kwawo wonke amadivayisi ochungechungeni lomkhiqizo.Wonke amadivayisi ahlanganisa okuphathelene nokuxhumana okuhlakaniphile nokuguquguqukayo, Isistimu Yomcimbi yokusayinda kwe-inter-peripheral, nosekelo lwenkinobho yokuthinta i-capacitive, isilayidi, nokuxhumana komsebenzisi wamasondo.I-SAM D21/DA1 inikeza izici ezilandelayo: I-Flash ehlelekayo yangaphakathi nohlelo, Isilawuli Sokufinyelela Kwememori Esiqondile (DMAC) seshaneli engu-12, Uhlelo Lwemicimbi yeziteshi eziyi-12, Isilawuli Esiphazamisayo esihlelekayo, izikhonkwane ze-I/O ezingafika ku-52, 32-bit Real. -Iwashi Lesikhathi Nekhalenda (RTC), kufikela ku-16-bit Timer/Counters (TC) kuze kufike ku-24-bit Timer/Counters for Control (TCC), lapho i-TC ngayinye ingalungiselelwa ukwenza imvamisa nesizukulwane se-waveform, isikhathi sokwenza uhlelo olunembile noma ukuthwebula okokufaka kanye nesilinganiso sesikhathi nemvamisa yamasignali edijithali.Ama-TC angasebenza ngemodi engu-8-bit noma engu-16-bit, ama-TC akhethiwe angadalulwa ukuze akhe i-32-bit TC, futhi izibali-sikhathi/izibali ezintathu zinemisebenzi enwetshiwe elungiselelwe injini, ukukhanya, nezinye izinhlelo zokusebenza zokulawula.Uchungechunge luhlinzeka ngosokhaya oyedwa oshumekiwe we-USB 2.0 ogcwele isivinini kanye nesixhumi esibonakalayo sedivayisi;kufika kuma-Serial Communication Modules (SERCOM) ngalinye elingalungiselelwa ukuthi lisebenze njenge-USART, UART, SPI, I2C kufika ku-3.4 MHz, SMBus, PMBus, kanye neklayenti le-LIN;isixhumi esibonakalayo seziteshi ezimbili ze-I 2S;kufika kumashaneli angamashumi amabili we-350 ksps 12-bit ADC enenzuzo ehlelekayo kanye nokukhethwa kwesampula okweqile kanye nokuncishiswa okusekela ukulungiswa okufika kokungu-16-bit, okukodwa okungu-10-bit 350 ksps DAC, kufika kuzifanisi ezine ze-analogi ezinemodi yeWindow, Peripheral Touch Controller (PTG) isekela izinkinobho, izilayidi, amasondo, nezinzwa eziseduze;I-Watchdog Timer (WDT) ehlelekayo (i-WDT), isitholi esinsundu namandla okusetha kabusha kanye nohlelo lwamaphini amabili we-serial Wire Debug (SWD) nesixhumi esibonakalayo sokususa iphutha.Wonke amadivayisi anama-oscillator anembile nanamandla aphansi angaphandle nawangaphakathi.Wonke ama-oscillator angasetshenziswa njengomthombo wewashi lesistimu.Izizinda zewashi ezihlukene zingalungiselelwa ngokuzimela ukuthi zisebenze kumafrikhwensi ahlukene, zinike amandla ukonga amandla ngokusebenzisa i-peripheral ngayinye kumafrikhwensi ewashi afanele, futhi ngaleyo ndlela kugcinwe imvamisa ephezulu ye-CPU ngenkathi kunciphisa ukusetshenziswa kwamandla.
