I-ATXMEGA128A1U-AU 8bit Microcontrollers MCU 100TQFP IND TEMP GREEN 1.6-3.6V

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 iziqondiso ngomjikelezo wewashi elilodwa, amadivayisi we-AVR XMEGA afinyelela ukusebenza kwe-CPU kufinyelela emiyalweni eyisigidi ngomzuzwana (i-MIPS) nge-megahertz ngayinye, okuvumela umklami wohlelo ukuthi athuthukise ukusetshenziswa kwamandla ngokumelene nesivinini sokucubungula.

I-Atmel AVR CPU ihlanganisa isethi yemiyalelo ecebile namarejista okusebenza ngezinjongo ezijwayelekile ezingu-32. Wonke amarejista angu-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 A1U 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 sokuphazamisa amazinga amaningi, imigqa ye-I/O yenjongo evamile engama-78, ikhawunta yesikhathi sangempela engu-16-bit (RTC); eziyisishiyagalombili eziguquguqukayo, i-16-bit timer/counter ezineziteshi zokuqhathanisa ne-PWM, ama-UART ayisishiyagalombili; ezine-two-wire serial interfaces (TWIs); isixhumi esibonakalayo esisodwa esigcwele isivinini se-USB 2.0; ama-serial peripheral interfaces (ama-SPI); Injini ye-cryptographic ye-AES ne-DES; Ijeneretha ye-CRC-16 (CRC-CCITT) ne-CRC-32 (IEEE 802.3); amashaneli amabili angu-16, ama-ADC angu-12-bit anenzuzo ehlelekayo; amashaneli amabili angu-2, ama-DAC angu-12-bit; Izifanisi 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.

Amadivayisi we-XMEGA A1U anezinhlelo ezinhlanu zokonga amandla ezikhethwa yisoftware. Imodi yokungenzi lutho imisa i-CPU ngenkathi ivumela i-SRAM, isilawuli se-DMA, 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.

I-Atmel inikezela ngomtapo wezincwadi wamahhala we-QTouch wokushumeka izinkinobho zokuthinta, izilayidi nokusebenza kwamasondo kuma-microcontrollers e-AVR.

Idivayisi ikhiqizwa kusetshenziswa ubuchwepheshe benkumbulo obuphezulu be-Atmel, obungaguquki. Imemori ye-flash yohlelo ingahlelwa kabusha ohlelweni ngokusebenzisa i-PDI noma i-JTAG interface. Isilayishi sokuqalisa esisebenza kudivayisi singasebenzisa noma yisiphi isixhumi esibonakalayo ukulanda uhlelo lohlelo kumemori ye-flash. Isofthiwe yesilayishi sebhuthi esigabeni se-boot flash izoqhubeka nokusebenza ngenkathi isigaba se-flash yohlelo lokusebenza sibuyekezwa, sinikeze ukusebenza kwangempela kokufunda ngenkathi ubhala. Ngokuhlanganisa i-8/16-bit RISC CPU ne-in-system, i-flash ezihlelekayo, i-AVR XMEGA iwumndeni we-microcontroller onamandla ohlinzeka ngesixazululo esivumelana nezimo kakhulu nesibizayo sezinhlelo zokusebenza eziningi ezishumekiwe.

Wonke amadivayisi e-Atmel AVR XMEGA asekelwa ngohlelo oluphelele lwamathuluzi okuthuthukisa uhlelo, okuhlanganisa abahlanganisi be-C, izihlanganisi ezinkulu, isilungisi sephutha/izifanisi zohlelo, abahleli bezinhlelo, nezinsiza zokuhlola.
