I-ATXMEGA256C3-AUR IC MCU 8/16BIT 256KB FLSH 64TQFP

Incazelo

I-Atmel AVR XMEGA iwumndeni onamandla aphansi, ukusebenza okuphezulu, kanye nama-microcontrollers acebile angu-8/16-bit asekelwe ekwakhiweni kwe-AVR okuthuthukisiwe kwe-RISC.Ngokusebenzisa imiyalo ngomjikelezo wewashi elilodwa, amadivayisi we-AVR XMEGA afinyelela ukusebenza kwe-CPU kufinyelela emiyalweni eyisigidi ngesekhondi (i-MIPS) nge-megahertz ngayinye, okuvumela umklami wesistimu ukuthi athuthukise ukusetshenziswa kwamandla ngokumelene nesivinini sokucubungula.I-AVR CPU ihlanganisa isethi yemiyalo ecebile namarejista okusebenza ngezinjongo ezijwayelekile ezingu-32.Wonke amarejista angama-32 axhunywe ngokuqondile kuyunithi ye-arithmetic logic (ALU), okuvumela amarejista amabili azimele ukuthi afinyelelwe ngomyalelo owodwa, owenziwe ngomjikelezo wewashi owodwa.Isakhiwo esiwumphumela sisebenza kahle kakhulu ngekhodi kuyilapho sifinyelela imiphumela ngokushesha kaningi kune-accumulator eyodwa evamile noma ama-microcontrollers asekelwe ku-CISC.Amadivayisi we-XMEGA C3 ahlinzeka ngezici ezilandelayo: i-flash ehlelekayo engaphakathi nohlelo enekhono lokufunda ngenkathi ubhala;I-EEPROM yangaphakathi kanye ne-SRAM;isistimu yemicimbi yeziteshi ezine nesilawuli sokuphazamiseka kwamaleveli amaningi ahlelekayo, imigqa ye-I/O yenjongo evamile engu-50, ikhawunta yesikhathi sangempela engu-16-bit (RTC);ezinhlanu, i-16-bit timer/ikhawunta eneziteshi zokuqhathanisa ne-PWM;ama-USART amathathu;ama-serial interfaces anezintambo ezimbili (TWIs);isixhumi esibonakalayo esisodwa esigcwele isivinini se-USB 2.0;izixhumanisi ezimbili ze-serial peripheral (ama-SPI);ishaneli eyodwa eyishumi nesithupha, i-12-bit ADC enenzuzo ehlelekayo;iziqhathaniso ezimbili ze-analog (ACs) ezinemodi yewindi;i-watchdog timer ehlelekayo ene-oscillator yangaphakathi ehlukene;ama-oscillator angaphakathi anembile nge-PLL kanye ne-prescaler;kanye nokutholakala okunsundu okulungisekayo.Uhlelo nesixhumi esibonakalayo sokulungisa iphutha (PDI), isixhumi esibonakalayo esisheshayo, esinamaphini amabili sokuhlela nokulungisa iphutha, siyatholakala.Amadivayisi we-XMEGA C3 anezinhlelo ezinhlanu ezikhethekayo zokonga amandla.Imodi yokungenzi lutho imisa i-CPU ngenkathi ivumela i-SRAM, isistimu yomcimbi, isilawuli esiphazamisayo, nawo wonke ama-peripherals ukuthi aqhubeke nokusebenza.Imodi yokwehlisa amandla ilondoloza i-SRAM nokuqukethwe kwerejista, kodwa imisa ama-oscillator, ikhubaze yonke eminye imisebenzi kuze kube i-TWI elandelayo, ukuqalisa kabusha kwe-USB, noma ukuphazamisa ukushintsha kwephini, noma ukusetha kabusha.Kumodi yokonga amandla, isibali sesikhathi sangempela esingavumelanisiwe siyaqhubeka nokusebenza, okuvumela uhlelo lokusebenza ukuthi lugcine isibali sikhathi ngenkathi yonke idivayisi ilele.Kumodi yokulinda, i-crystal oscillator yangaphandle iqhubeka nokusebenza ngenkathi yonke idivayisi ilele.Lokhu kuvumela ukuqalisa okusheshayo kusuka kukristalu yangaphandle, kuhlanganiswe nokusetshenziswa kwamandla okuphansi.Kumodi yokulinda enwetshiwe, kokubili i-oscillator eyinhloko nesibali-sikhathi esingavumelanisiwe kuyaqhubeka nokusebenza.Ukuze kuqhutshekwe nokunciphisa ukusetshenziswa kwamandla, iwashi eliwumngcele weperipheral ngayinye lingakhethwa ngokuzithandela kumodi esebenzayo kanye nemodi yokulala engenzi lutho.
