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

I-Atmel AVR XMEGA yintsapho enamandla aphantsi, ukusebenza okuphezulu, kunye ne-peripheral rich 8/16-bit microcontrollers esekwe kwi-AVR ephuculweyo ye-RISC yoyilo. Ngokusebenzisa imiyalelo kumjikelo wewotshi enye, izixhobo ze-AVR XMEGA zifikelela kwi-CPU efikelela kwisigidi semiyalelo ngomzuzwana (MIPS) nge-megahertz nganye, evumela umyili wenkqubo ukuba andise ukusetyenziswa kwamandla xa kuthelekiswa nesantya sokusebenza.

I-Atmel AVR CPU idibanisa umyalelo ocebileyo kunye neerejista ze-32 ezisebenza ngokubanzi. Zonke iirejista ze-32 ziqhagamshelwe ngokuthe ngqo kwiyunithi ye-arithmetic logic (ALU), evumela iirejista ezimbini ezizimeleyo ukuba zifikeleleke kumyalelo omnye, owenziwe kumjikelo wewotshi enye. Ulwakhiwo olunesiphumo lusebenza kakuhle kakhulu ngekhowudi ngelixa uphunyezwa ngokuphindaphinda amaxesha amaninzi ngokukhawuleza kunesiqhelo esiqhelekileyo se-accumulator okanye i-microcontrollers esekwe kwiCISC.

Izixhobo ze-AVR XMEGA A1U zibonelela ngezi mpawu zilandelayo: i-flash ecwangcisiweyo ye-in-system kunye nokukwazi ukufunda ngelixa-ubhala; I-EEPROM yangaphakathi kunye ne-SRAM; isilawuli se-DMA esine-channel ezine, inkqubo yesiganeko se-channel esibhozo kunye ne-programmable multilevel interrupt controller, imigca ye-78 yenjongo jikelele ye-I / O, i-16-bit ye-real-time counter (RTC); ezisibhozo eziguquguqukayo, i-16-bit timer / counters ngokuthelekisa kunye neziteshi ze-PWM, ii-USART ezisibhozo; ezine-two-two serial interfaces (TWIs); isantya esinye esipheleleyo se-USB 2.0 ujongano; ujongano lwe peripheral ezine (SPIs); Injini ye-cryptographic ye-AES kunye ne-DES; CRC-16 (CRC-CCITT) kunye CRC-32 (IEEE 802.3) generator; ezimbini 16-itshaneli, 12-bit ADCs ngenzuzo programmable; ezimbini 2-itshaneli, 12-bit DACs; ezine ze-Analog Comparators (ACs) ezinemowudi yefestile; i-watchdog timer ecwangcisiweyo ene-oscillator yangaphakathi eyahlukileyo; ii-oscillators ezichanekileyo zangaphakathi kunye ne-PLL kunye ne-prescaler; kunye nobhaqo olucwangcisiweyo olumdaka.

Inkqubo kunye ne-debug interface (PDI), i-interface ekhawulezayo, ene-pin-pin yeprogram kunye nokulungiswa kweempazamo, iyafumaneka. Izixhobo nazo zine-IEEE std. I-1149.1 ihambelana ne-JTAG interface, kwaye oku kungasetyenziselwa ukuskena komda, ukulungiswa kwe-chip kunye neprogram.

Izixhobo ze-XMEGA A1U zineendlela ezintlanu zokugcina amandla ezikhethiweyo. Imowudi yokungasebenzi imisa i-CPU ngelixa ivumela i-SRAM, isilawuli se-DMA, inkqubo yesiganeko, isilawuli esiphazamisayo, kunye nazo zonke iiperipherals ukuba ziqhubeke nokusebenza. Imowudi yokunciphisa amandla igcina i-SRAM kunye nemixholo yokubhalisa, kodwa imisa i-oscillators, ikhubaza yonke eminye imisebenzi kude kube yi-TWI elandelayo, i-USB iphinde iqalise, okanye i-pin-change interrupt, okanye usethe kwakhona. Kwimowudi yokonga amandla, i-asynchronous real-time counter iyaqhubeka nokusebenza, ivumela usetyenziso ukuba lugcine isiseko sesibali-xesha ngelixa esinye isixhobo silele. Kwimowudi yokulinda, i-oscillator yekristale yangaphandle iqhubeka isebenza ngelixa sonke isixhobo silele. Oku kuvumela ukuqalisa ngokukhawuleza kakhulu ukusuka kwikristale yangaphandle, kudibaniswa nokusetyenziswa kwamandla aphantsi. Kwimo yokulinda eyandisiweyo, zombini i-oscillator ephambili kunye ne-asynchronous timer iyaqhubeka nokusebenza. Ukunciphisa ngakumbi usetyenziso lwamandla, iwotshi ejikelezayo kumda womntu ngamnye inokumiswa ngendlela esebenzayo kunye nemo yokulala engasebenziyo.

I-Atmel ibonelela ngethala leencwadi le-QTouch lasimahla lokushumeka amaqhosha ocofa amandla, izilayidi kunye nokusebenza kwamavili kwii-microcontrollers ze-AVR.

Isixhobo senziwa kusetyenziswa i-Atmel high-density, iteknoloji yememori engaguqukiyo. Imemori yenkqubo yeflash inokuphinda icwangciswe kwinkqubo ngokusebenzisa iPDI okanye iJTAG ujongano. Umlayishi we-boot osebenza kwisixhobo unokusebenzisa naluphi na ujongano ukukhuphela inkqubo yesicelo kwimemori yeflash. Isoftware yomlayishi we-boot kwicandelo le-flash ye-boot iya kuqhubeka iqhuba ngelixa icandelo le-flash yesicelo lihlaziywa, ibonelela ngomsebenzi wokufunda-ngelixa ubhala. Ngokudibanisa i-8/16-bit RISC CPU kunye ne-in-system, i-flash self-programmable, i-AVR XMEGA yintsapho ye-microcontroller enamandla enika isisombululo esiguquguqukayo kakhulu kunye nexabiso elisebenzayo kwizicelo ezininzi ezifakwe ngaphakathi.

Zonke izixhobo ze-Atmel AVR XMEGA zixhaswa nge-suite epheleleyo yenkqubo kunye nezixhobo zophuhliso lwenkqubo, kubandakanywa abaqulunqi be-C, abahlanganisi be-macro, i-debugger yeprogram / i-simulators, abaprogram, kunye neekiti zokuvavanya.
