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

Inkcazo

I-Atmel AVR XMEGA lusapho olunamandla 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-CPU ye-AVR idibanisa umyalelo ocebileyo kunye neerejista ze-32 eziqhelekileyo zokusebenza.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 kuphunyezwa ngokuphindaphinda amaxesha amaninzi ngokukhawuleza kunesiqhelo i-accumulator enye okanye i-microcontrollers esekwe kwiCISC.Izixhobo ze-XMEGA C3 zibonelela ngezi mpawu zilandelayo: i-flash ecwangcisiweyo ekwi-system enobuchule bokufunda-ngelixa-bhalayo;I-EEPROM yangaphakathi kunye ne-SRAM;inkqubo yesiganeko sesiteshi esine kunye nesilawuli sokuphazamiseka kwe-multilevel esicwangcisiweyo, imigca ye-50 yenjongo jikelele ye-I / O, i-16-bit real-time counter (RTC);ezintlanu, i-16-bit timer/izixhobo zokubala ezinokuthelekisa kunye nemijelo ye-PWM;ezintathu UARTs;ujongano lweengcingo ezimbini (TWIs);isantya esinye esipheleleyo se-USB 2.0 ujongano;ujongano olulandelelanayo lweperipheral (SPIs);itshaneli enye elinesithandathu, i-12-bit ADC enenzuzo enokucwangciswa;abathelekisi ababini be-analog (ACs) ngemo 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 ze-XMEGA C3 zineendlela ezintlanu ezikhethiweyo zokugcina amandla esoftware.Imowudi yokungasebenzi imisa i-CPU ngelixa ivumela i-SRAM, inkqubo yomsitho, 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.
