ATSAMD21J18A-AU IC MCU 32BIT 256KB IFLESHI 64TQFP

Inkcazo

I-SAM D21 / DA1 luhlu lwe-microcontrollers yamandla aphantsi usebenzisa i-32-bit Arm® Cortex®-M0 + iprosesa, kwaye isuka kwi-32-pins ukuya kwi-64-pins ukuya kwi-256 KB Flash kunye ne-32 KB ye-SRAM.I-SAM D21 / DA1 isebenza kwi-frequency ephezulu ye-48 MHz kwaye ifike kwi-2.46 CoreMark / MHz.Ziyilelwe ukufuduka okulula kunye nokubonakalayo kunye neemodyuli zeperipheral ezifanayo, ikhowudi ye-hex ehambelanayo, imephu yedilesi efanayo, kunye neendlela zokufuduka ezihambelanayo phakathi kwazo zonke izixhobo ezikuluhlu lwemveliso.Zonke izixhobo zibandakanya iiperipherals ezikrelekrele kunye neziguquguqukayo, iNkqubo yeSigigaba yokubonisa i-inter-peripheral, kunye nenkxaso yeqhosha lokuchukumisa i-capacitive, isilayidi, kunye nojongano lomsebenzisi wevili.I-SAM D21/DA1 ibonelela ngezi mpawu zilandelayo: I-Flash ecwangcisiweyo yangaphakathi, i-12-channel Direct Memory Access Controller (DMAC), iNkqubo yeSigigaba se-12-channel, isiLawuli esiPhakamileyo esicwangcisiweyo, ukuya kuthi ga kwi-52 i-programmable I/O izikhonkwane, i-32-bit Real. -Ixesha leClock kunye neKhalenda (RTC), ukuya kuthi ga kwi-16-bit Timer / Counters (TC) ukuya kuthi ga kwi-24-bit Timer / Counters for Control (TCC), apho i-TC nganye inokuqwalaselwa ukuba yenze i-frequency kunye ne-waveform generation, Ixesha lokwenziwa kwenkqubo echanekileyo okanye ukufakwa kwegalelo kunye nexesha kunye nomlinganiselo wobuninzi beempawu zedijithali.I-TCs inokusebenza kwi-8-bit okanye i-16-bit mode, ii-TC ezikhethiweyo zinokuthi zenziwe i-cascade ukuze zenze i-32-bit TC, kunye ne-timer / counters ezintathu ziye zandisa imisebenzi elungiselelwe i-motor, ukukhanya, kunye nezinye iinkqubo zokulawula.Olu luhlu lubonelela ngesantya esigcweleyo se-USB 2.0 ibamba kunye nojongano lwesixhobo;ukuya kuthi ga kwiiModyuli zoNxibelelwano lweSiri ezintandathu (SERCOM) ukuba nganye inokumiselwa ukuba isebenze njenge USART, UART, SPI, I2C ukuya kuthi ga kwi3.4 MHz, SMBus, PMBus, kunye nomxhasi weLIN;ujongano lwamajelo amabini I 2S;ukuya kuthi ga kumashumi amabini amatshaneli 350 ksps 12-bit ADC ngenzuzo ecwangcisiweyo kunye nokuzikhethela oversampling kunye nokunciphisa ukuxhasa ukuya kuthi ga kwi-16-bit isisombululo, enye 10-bit 350 ksps DAC, ukuya kuthi ga kwizithelekiso ze-analog ezine kunye nemowudi ye-Window, i-Peripheral Touch Controller (PTG) ixhasa ukuya kuthi ga kumaqhosha angama-256, izilayidi, amavili, kunye nokuziva kufutshane;programmable Watchdog Timer (WDT), brown-out detector kunye namandla-on Ukuseta kwakhona kunye neepin ezimbini Uthotho Wire Debug (SWD) inkqubo kunye nojongano debug.Zonke izixhobo zinee-oscillator ezichanekileyo kunye neziphantsi kwamandla angaphandle nangaphakathi.Zonke ii-oscillators zingasetyenziswa njengomthombo wewotshi yenkqubo.Imimandla yewotshi eyahlukeneyo inokumiswa ngokuzimeleyo ukuba isebenze kumaza ahlukeneyo, ivumela ukongiwa kwamandla ngokuqhuba iperipheral nganye kwi-frequency yayo yewotshi echanekileyo, kwaye ngaloo ndlela igcina i-frequency ephezulu ye-CPU ngelixa unciphisa ukusetyenziswa kwamandla.
