I-ATXMEGA256A3U-MH IC MCU 8/16BIT 256KB IFLASH 64QFN

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.Ngokwenza imiyalelo ngomjikelezo wewashi elilodwa, idivayisi ye-AVR XMEGA ifinyelela i-CPU efinyelela emiyalweni eyisigidi ngomzuzwana (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-AVR XMEGA A3U ahlinzeka ngezici ezilandelayo: i-flash ehlelekayo engaphakathi nohlelo enekhono lokufunda ngenkathi ubhala;I-EEPROM yangaphakathi kanye ne-SRAM;isilawuli se-DMA seziteshi ezine, isistimu yemicimbi yamashaneli ayisishiyagalombili nesilawuli sokuphazamiseka kwamaleveli amaningi, imigqa ye-I/O yenjongo evamile engu-50, ikhawunta yesikhathi sangempela engu-16-bit (RTC);eziyisikhombisa eziguquguqukayo, eziyi-16-bit timer/ikhawunta ezineziteshi zokuqhathanisa ne-PWM;ama-USART ayisikhombisa;ama-serial interfaces anezintambo ezimbili (TWIs);isixhumi esibonakalayo esisodwa esigcwele isivinini se-USB 2.0;ezintathu serial peripheral interfaces (SPIs);Injini ye-cryptographic ye-AES ne-DES;amashaneli amabili angu-16, ama-ADC angu-12-bit anenzuzo ehlelekayo;ishaneli engu-2 eyodwa engu-12-bit DAC;iziqhathaniso ezine 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 nawo ane-IEEE std.1149.1 isixhumi esibonakalayo se-JTAG, futhi lokhu kungase futhi kusetshenziselwe ukuskena komngcele, ukulungisa iphutha ku-chip kanye nokwenza izinhlelo.
