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

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, loaʻa i nā polokalamu AVR XMEGA ka CPU throughput e kokoke ana i hoʻokahi miliona mau kuhikuhi i kēlā me kēia kekona (MIPS) no megahertz, e ʻae ana i ka mea hoʻolālā ʻōnaehana e hoʻonui i ka hoʻohana ʻana i ka mana me ka wikiwiki o ka hana.

Hoʻohui ka Atmel AVR CPU i kahi hoʻonohonoho aʻo 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 A1U i kēia mau hiʻohiʻona: in-system programmable flash me nā hiki heluhelu-while-write;EEPROM kūloko a me SRAM;ʻEhā kanal DMA hoʻoponopono, ʻewalu kaila ʻōnaehana hanana a me ka programmable multilevel interrupt controller, 78 kumu nui I/O laina, 16-bit real-time counter (RTC);ʻewalu maʻalahi, 16-bit timer/counters me ka hoʻohālikelike a me nā kaha PWM, ʻewalu USART;ʻehā mau uea serial interface (TWIs);hoʻokahi kikowaena USB 2.0 wikiwiki piha;ʻehā mau kikowaena peripheral serial (SPI);AES a me DES mīkini cryptographic;CRC-16 (CRC-CCITT) a me CRC-32 (IEEE 802.3) generator;ʻelua 16-channel, 12-bit ADCs me ka loaʻa programmable;ʻelua 2-channel, 12-bit DACs;ʻehā Analog Comparators (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.

Aia nā polokalamu XMEGA A1U i ʻelima mau polokalamu hoʻopakele mana koho.Hoʻopau ke ʻano hana ʻole i ka CPU ʻoiai e ʻae ana i ka SRAM, DMA controller, event system, interrupt controller, a me nā peripheral āpau e hoʻomau i ka hana.Mālama ka mana-down mode i ka SRAM a hoʻopaʻa inoa i nā ʻike, akā hoʻōki i nā oscillators, hoʻopau i nā hana ʻē aʻe a hiki i ka TWI aʻe, hoʻomaka USB, a i ʻole ke hoʻololi i ka pin-change interrupt, a i ʻole ka hoʻonohonoho hou.Ma ke ʻano hoʻōla mana, hoʻomau ka holo ʻana o ka counter-time asynchronous, e ʻae ana i ka noi e mālama i kahi kumu manawa i ka wā e hiamoe ana ke koena o ka hāmeʻa.Ma ke ʻano kuʻuna, e holo mau ana ka oscillator kristal waho i ka wā e hiamoe ana ke koena o ka hāmeʻa.Hāʻawi kēia i ka hoʻomaka wikiwiki loa mai ke aniani o waho, i hui pū ʻia me ka hoʻohana haʻahaʻa haʻahaʻa.Ma ke ʻano kuʻuna lōʻihi, e holo mau ana ka oscillator nui a me ka manawa asynchronous.No ka hoʻemi hou ʻana i ka hoʻohana ʻana i ka mana, hiki ke pani ʻia ka uaki peripheral i kēlā me kēia peripheral i ke ʻano hana a me ke ʻano hiamoe ʻole.

Hāʻawi ʻo Atmel i kahi waihona QTouch manuahi no ka hoʻopili ʻana i nā pihi capacitive touch, nā paheʻe a me nā hana huila i loko o nā microcontrollers AVR.

Hana ʻia ka mea hana me ka hoʻohana ʻana i ka ʻenehana hoʻomanaʻo nonvolatile kiʻekiʻe ʻo Atmel.Hiki ke hoʻonohonoho hou ʻia ka hoʻomanaʻo ʻana o ka polokalamu ma o ka PDI a i ʻole JTAG.Hiki i ka mea hoʻoili pahu e holo ana i loko o ka hāmeʻa ke hoʻohana i kekahi interface e hoʻoiho i ka polokalamu noi i ka hoʻomanaʻo flash.E hoʻomau ka holo ʻana o ka polokalamu boot loader ma ka ʻāpana boot flash i ka wā e hoʻonui ʻia ai ka pauku flash application, e hāʻawi ana i ka hana heluhelu-ʻoiai-kākau.Ma ka hoʻohui ʻana i kahi 8/16-bit RISC CPU me ka in-system, pono-programmable flash, ʻo ka AVR XMEGA he ʻohana microcontroller ikaika e hāʻawi i kahi hopena maʻalahi a maikaʻi hoʻi no ka nui o nā noi i hoʻopili ʻia.

Kākoʻo ʻia nā mea hana a pau o Atmel AVR XMEGA me kahi pūʻulu piha o ka papahana a me nā mea hana hoʻomohala ʻōnaehana, me ka C compilers, macro assemblers, program debugger/simulators, programmers, a me nā pahu loiloi.
