He ʻohana ʻo Atmel AVR XMEGA me ka mana haʻahaʻa, ka hana kiʻekiʻe, a me nā microcontrollers 8/16-bit waiwai nui e pili ana i ka hoʻolālā RISC i hoʻonui ʻia e AVR.Ma ka hoʻokō ʻana i nā ʻōlelo aʻoaʻo i hoʻokahi pōʻai uaki hoʻokahi, loaʻa ka hāmeʻa AVR XMEGA i nā throughputs CPU e kokoke ana i hoʻokahi miliona mau kuhikuhi i kēlā me kēia kekona (MIPS) no ka megahertz, e ʻae ana i ka mea hoʻolālā ʻōnaehana e hoʻonui i ka hoʻohana mana me ka wikiwiki o ka hana.Hoʻohui ka AVR CPU i kahi hoʻonohonoho aʻoaʻo waiwai me 32 mau papa inoa hana maʻamau.Hoʻopili pololei ʻia nā papa inoa 32 a pau i ka helu helu helu (ALU), e ʻae ana i ʻelua mau papa inoa kūʻokoʻa e komo i loko o kahi aʻo hoʻokahi, i hana ʻia i hoʻokahi pōʻai uaki.ʻOi aku ka maikaʻi o ka hoʻolālā ʻana i ka code ʻoiai e loaʻa ana nā throughputs i nā manawa he nui ma mua o nā microcontrollers hoʻokahi-accumulator maʻamau a i ʻole CISC.Hāʻawi nā mea hana AVR XMEGA A3U i kēia mau hiʻohiʻona: in-system programmable flash me nā hiki heluhelu-whilewrite;EEPROM kūloko a me SRAM;ʻEhā kanal DMA hoʻoponopono, ʻewalu kanal ʻōnaehana hanana a me ka programmable multilevel interrupt controller, 50 kumu nui laina I/O, 16-bit real-time counter (RTC);ʻehiku maʻalahi, 16-bit timer/counters me ka hoʻohālikelike a me nā kaha PWM;ʻehiku USART;ʻelua mau laina laina laina ʻelua (TWI);hoʻokahi kikowaena USB 2.0 wikiwiki piha;ʻekolu mau kikowaena peripheral serial (SPI);AES a me DES mīkini cryptographic;ʻelua 16-channel, 12-bit ADCs me ka loaʻa programmable;hoʻokahi 2-channel 12-bit DAC;ʻehā mau mea hoʻohālikelike analog (AC) me ke ʻano pukaaniani;ʻO ka manawa kiaʻi polokalamu me ka oscillator kūloko kaʻawale;nā oscillators kūloko kūpono me PLL a me ka prescaler;a me ka ʻike brown-out programmable.Loaʻa ka polokalamu a me ka debug interface (PDI), kahi wikiwiki, ʻelua pin no ka hoʻonohonoho ʻana a me ka debugging.Loaʻa i nā hāmeʻa kahi IEEE std.1149.1 hoʻokō JTAG interface, a hiki ke hoʻohana ʻia kēia no ka nānā ʻana i ka palena, ka debug ma luna o ka chip a me ka polokalamu.
