ATSAMD21G18A-AU IC MCU 32BIT 256KB FLASH 48TQFP

Tsanangudzo

Iyo SAM D21/DA1 inotevedzana yepasi-simba mamicrocontrollers anoshandisa iyo 32-bit Arm® Cortex®-M0+ processor, uye kubva pa32-pini kusvika 64-pini inosvika 256 KB Flash uye 32 KB yeSRAM.Iyo SAM D21/DA1 inoshanda pamwero mukuru we48 MHz uye inosvika 2.46 CoreMark/MHz.Iwo akagadzirirwa nyore uye intuitive kutama ane akafanana peripheral modules, hex inoenderana kodhi, yakafanana mutsara kero mepu, uye pini inoenderana yekutama nzira pakati pezvishandiso zvese mumutsara wechigadzirwa.Zvishandiso zvese zvinosanganisira akangwara uye anochinjika peripherals, Chiitiko System yekusaina-yepakati-yepakati, uye tsigiro yecapacitive yekubata bhatani, inotsvedza, uye vhiri mushandisi nzvimbo.Iyo SAM D21/DA1 inopa zvinhu zvinotevera: In-system programmable Flash, 12-channel Direct Memory Access Controller (DMAC), 12-channel Chiitiko System, programmable Interrupt Controller, anosvika 52 programmable I/O pini, 32-bit Real. -Time Clock neKarenda (RTC), kusvika kushanu 16-bit Timer/Counters (TC) uye kusvika ina 24-bit Timer/Counters for Control (TCC), uko TC imwe neimwe inogona kugadzirwa kuti iite frequency uye waveform generation, kwakaringana chirongwa chekuita nguva kana kupinza kutora nenguva uye frequency kuyerwa kwemasaini edhijitari.MaTC anogona kushanda mu8-bit kana 16-bit modhi, maTC akasarudzwa anogona kukandwa kuti aite 32-bit TC, uye matatu timer/counter akawedzera mabasa akakwenenzverwa emota, mwenje, uye mamwe maitiro ekudzora.Iwo akatevedzana anopa imwe yakazara-speed USB 2.0 yakamisikidzwa host uye mudziyo interface;anosvika matanhatu Serial Kukurukurirana Modules (SERCOM) iyo imwe neimwe inogona kugadzirwa kuti iite seUSART, UART, SPI, I2C kusvika 3.4 MHz, SMBus, PMBus, uye LIN mutengi;maviri-chiteshi I 2S interface;kusvika pamakumi maviri-channel 350 ksps 12-bit ADC ine programmable kuwana uye sarudzo yakawandisa uye decimation inotsigira kusvika ku16-bit resolution, imwe 10-bit 350 ksps DAC, anosvika mana anoenzanisa analogi ane Window mode, Peripheral Touch Controller (PTG) inotsigira mabhatani anosvika mazana maviri nemakumi mashanu nematanhatu, masiraidhi, mavhiri, uye kuona padhuze;programmable Watchdog Timer (WDT), brown-out detector uye simba-pa Reset uye maviri-pini Serial Wire Debug (SWD) chirongwa uye debug interface.Midziyo yese ine chaiyo uye yakaderera-simba ekunze uye emukati oscillators.Ese oscillator anogona kushandiswa sesosi ye system wachi.Madomasi ewachi akasiyana anogona kugadzirwa akazvimirira kuti amhanye pama frequency akasiyana, achigonesa kuponesa simba nekumhanyisa peripheral yega yega panguva yayo yakakwana yewachi frequency, uye nekudaro kuchengetedza yakakwira CPU frequency uku ichideredza mashandisiro emagetsi.Iyo SAM D21/DA1 ine maviri software-selectable sleep modes, Idle uye Stand-by.Mune Idle mode, iyo CPU inomiswa nepo mamwe mabasa ese anogona kuchengetwa achimhanya.MuStand-by mode, wachi dzese nemabasa zvinomiswa, tarisira kuti avo vakasarudzwa varambe vachimhanya.Chishandiso chinotsigira SleepWalking.Iyi ficha inobvumira peripheral kumuka kubva mukurara zvichienderana neyakafanotsanangurwa mamiriro, uye nekudaro inobvumira iyo CPU kumuka chete kana ichidiwa, semuenzaniso, kana chikumbaridzo chayambuka kana mhedzisiro yagadzirira.Iyo Chiitiko Sisitimu inotsigira inopindirana uye asynchronous zviitiko, ichibvumira peripherals kugamuchira, kuita uye kutumira zviitiko kunyangwe muStand-by mode.Iyo Flash program memory inogona kudzokororwa mu-system kuburikidza neSWD interface.Iyo yakafanana interface inogona kushandiswa kune isiri-inopindira pa-chip debug yekodhi yekushandisa.Bootloader inomhanya mumudziyo inogona kushandisa chero nzira yekutaurirana kurodha uye kukwidziridza chirongwa chekushandisa muFlash memory.Iyo SAM D21/DA1 microcontrollers inotsigirwa izere sutu yechirongwa uye masisitimu ekuvandudza maturusi, anosanganisira C compilers, macro assemblers, chirongwa debugger/simulator, programmers, uye evaluation kits.
