Atmel AVR XMEGA ndi banja lamphamvu zochepa, magwiridwe antchito apamwamba, komanso zotumphukira zolemera za 8/16-bit microcontrollers kutengera kamangidwe ka AVR kopititsa patsogolo RISC.Pogwiritsa ntchito malangizo pawotchi imodzi, chipangizo cha AVR XMEGA chimakwaniritsa ma CPU oyandikira miliyoni miliyoni pa sekondi iliyonse (MIPS) pa megahertz, zomwe zimalola wopanga makinawo kuti azitha kukhathamiritsa kugwiritsa ntchito mphamvu poyerekeza ndi liwiro la kukonza.AVR CPU imaphatikiza malangizo ochulukirapo okhala ndi zolembera 32 zogwirira ntchito.Ma regista onse 32 amalumikizidwa mwachindunji ndi ma arithmetic logic unit (ALU), kulola kuti ma regista awiri odziyimira pawokha apezeke mu malangizo amodzi, ochitidwa mu wotchi imodzi.Zomangamanga zomwe zimapangidwira zimakhala zogwira mtima kwambiri ndikukwaniritsa zotulukapo mwachangu kwambiri kuposa ma single-accumulator okhazikika kapena ma microcontrollers a CISC.Zipangizo za AVR XMEGA A3U zimapereka zinthu zotsatirazi: kung'anima kosinthika mu dongosolo lokhala ndi luso lowerenga polemba;EEPROM yamkati ndi SRAM;wolamulira wa njira zinayi za DMA, makina asanu ndi atatu a zochitika za tchanelo ndi chowongolera chosokoneza ma multilevel, mizere 50 ya cholinga chachikulu cha I/O, 16-bit real-time counter (RTC);zisanu ndi ziwiri zosinthika, 16-bit timer/zowerengera zofananira ndi njira za PWM;ma USART asanu ndi awiri;awiri-waya serial interfaces (TWIs);mawonekedwe amodzi othamanga a USB 2.0;ma serial peripheral interfaces (SPIs);AES ndi DES cryptographic injini;ma 16-channel awiri, 12-bit ADCs ndi phindu lokonzekera;imodzi 2-channel 12-bit DAC;ma analogi anayi ofananira (ACs) okhala ndi mawonekedwe awindo;programmable watchdog timer ndi osiyana oscillator mkati;oscillators olondola mkati ndi PLL ndi prescaler;ndi kuzindikira kwa bulauni komwe kungakonzedwe.Pulogalamuyi ndi mawonekedwe a debug (PDI), mawonekedwe ofulumira, a mapini awiri opangira mapulogalamu ndi kukonza zolakwika, alipo.Zida zilinso ndi IEEE std.1149.1 yogwirizana ndi JTAG mawonekedwe, ndipo izi zitha kugwiritsidwanso ntchito pojambula malire, pa-chip debug ndi kukonza mapulogalamu.
