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

Kufotokozera

SAM D21/DA1 ndi mndandanda wa ma microcontrollers otsika kwambiri omwe amagwiritsa ntchito purosesa ya 32-bit Arm® Cortex®-M0+, ndipo kuyambira 32-pins mpaka 64-pins mpaka 256 KB Flash ndi 32 KB ya SRAM.SAM D21/DA1 imagwira ntchito pafupipafupi 48 MHz ndikufikira 2.46 CoreMark/MHz.Amapangidwira kusamuka kosavuta komanso kowoneka bwino kokhala ndi ma module ofanana, nambala yofananira ya hex, mamapu adilesi ofanana, ndi mapini osunthira omwe amalumikizana pakati pa zida zonse zomwe zili pamndandanda wazogulitsa.Zida zonse zikuphatikiza zotumphukira zanzeru komanso zosinthika, Makina Ochitika a ma sign apakati, komanso kuthandizira batani la capacitive touch, slider, ndi ma gudumu ogwiritsa ntchito.SAM D21/DA1 imapereka zinthu izi: In-system programmable Flash, 12-channel Direct Memory Access Controller (DMAC), 12-channel Event System, Programmable Interrupt Controller, mpaka 52 programmable I/O pini, 32-bit Real -Time Clock ndi Calendar (RTC), mpaka asanu 16-bit Timer/Counters (TC) mpaka anayi 24-bit Timer/Counters for Control (TCC), pomwe TC iliyonse imatha kukhazikitsidwa kuti ipange ma frequency ndi ma waveform generation, nthawi yolondola yoyendetsera pulogalamu kapena kujambula kolowera ndi nthawi komanso kuchuluka kwa ma siginecha a digito.Ma TC amatha kugwira ntchito mu 8-bit kapena 16-bit mode, ma TC osankhidwa amatha kusinthidwa kuti apange 32-bit TC, ndipo ma timer/counters atatu ali ndi ntchito zowonjezera zokongoletsedwa ndi injini, kuyatsa, ndi ntchito zina zowongolera.Zotsatizanazi zimapereka mpata umodzi wokhazikika wa USB 2.0 ndi mawonekedwe a chipangizo;mpaka asanu ndi limodzi ma seri Communication Modules (SERCOM) omwe aliyense akhoza kusinthidwa kuti akhale ngati USART, UART, SPI, I2C mpaka 3.4 MHz, SMBus, PMBus, ndi LIN kasitomala;mawonekedwe awiri njira I 2S;mpaka 350 ksps 350 ksps 12-bit ADC yokhala ndi phindu lokonzekera ndikusankha mopitilira muyeso ndi kutsika komwe kumathandizira mpaka 16-bit resolution, 10-bit 350 ksps DAC, mpaka ma analogi anayi ofananira okhala ndi Window mode, Peripheral Touch Controller (PTG) kuthandizira mpaka mabatani 256, zoyenda, mawilo, ndi zowonera pafupi;programmable Watchdog Timer (WDT), chojambulira chabulauni ndi mphamvu pa Bwezerani ndi pulogalamu yamapini awiri Serial Wire Debug (SWD) ndi mawonekedwe owongolera.Zida zonse zili ndi oscillator olondola komanso otsika akunja ndi mkati.Ma oscillator onse atha kugwiritsidwa ntchito ngati gwero la wotchi yamakina.Mawotchi osiyanasiyana amatha kukhazikitsidwa pawokha kuti aziyenda mosiyanasiyana, kupangitsa kupulumutsa mphamvu poyendetsa chotumphukira chilichonse pawotchi yake yoyenera, ndikusunga ma frequency apamwamba a CPU ndikuchepetsa kugwiritsa ntchito mphamvu.SAM D21/DA1 ili ndi mitundu iwiri yogona yosankha mapulogalamu, Idle ndi Stand-by.Mu Idle mode, CPU imayimitsidwa pomwe ntchito zina zonse zitha kuyendetsedwa.Mu Stand-by mode, mawotchi onse ndi ntchito zimayimitsidwa, yembekezerani omwe asankhidwa kuti apitirize kuthamanga.Chipangizochi chimathandizira SleepWalking.Mbaliyi imalola kuti zotumphukira zidzuke ku tulo potengera zomwe zafotokozedweratu, motero zimalola CPU kudzuka pokhapokha ngati ikufunika, mwachitsanzo, podutsa malire kapena zotsatira zake zakonzeka.The Event System imathandizira zochitika zofananira komanso zosasinthika, kulola zotumphukira kulandira, kuchitapo kanthu ndikutumiza zochitika ngakhale mumayendedwe a Stand-by.Kukumbukira kwa pulogalamu ya Flash kumatha kukonzedwanso mu dongosolo kudzera mu mawonekedwe a SWD.Mawonekedwe omwewo angagwiritsidwe ntchito pochotsa zolakwika pa-chip-code code.Chojambulira cha boot chomwe chikuyenda mu chipangizochi chimatha kugwiritsa ntchito mawonekedwe aliwonse olankhulirana kutsitsa ndikukweza pulogalamuyo mu Flash memory.Ma microcontrollers a SAM D21/DA1 amathandizidwa ndi zida zonse za pulogalamu ndi kachitidwe kachitidwe, kuphatikiza C compilers, macro assemblers, program debugger/simulators, programmers, and evaluation kits.
