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

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, isixhobo se-AVR XMEGA sifikelela kwi-CPU efikelela kwisigidi semiyalelo ngomzuzwana (MIPS) nge-megahertz nganye, ivumela umyili wenkqubo ukuba asebenzise amandla ombane kunye nesantya sokuqhubekeka.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-AVR XMEGA A3U zibonelela ngezi mpawu zilandelayo: i-flash programmable ekwinkqubo enobuchule bokufunda-ngelixa bhalayo;I-EEPROM yangaphakathi kunye ne-SRAM;isilawuli se-DMA esine-channel ezine, inkqubo yesiganeko seshaneli esibhozo kunye nesilawuli sokuphazamiseka kwe-multilevel esicwangcisiweyo, imigca ye-50 yenjongo jikelele ye-I / O, i-16-bit real-time counter (RTC);ezisixhenxe eziguquguqukayo, i-16-bit timer/ikhawuntasi ezinokuthelekisa kunye nemijelo ye-PWM;ii-USART ezisixhenxe;ujongano lweengcingo ezimbini (TWIs);isantya esinye esipheleleyo se-USB 2.0 ujongano;ezintathu ezilandelelanayo ujongano lweperipheral (SPIs);Injini ye-cryptographic ye-AES kunye ne-DES;ezimbini 16-itshaneli, 12-bit ADCs ngenzuzo programmable;enye i-2-channel 12-bit DAC;abathelekisi abane be-analog (ACs) abanemo 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.
