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

Atmel AVR XMEGA dangi ne mai ƙarancin ƙarfi, babban aiki, da na'urori masu ƙarfi na 8/16-bit mai ƙarfi dangane da haɓakar gine-ginen RISC na AVR. Ta hanyar aiwatar da umarni a cikin zagayowar agogo ɗaya, na'urorin AVR XMEGA suna samun nasarar samar da kayan aikin CPU suna kusantar umarni miliyan ɗaya a cikin sakan daya (MIPS) a kowace megahertz, yana ba mai ƙirar tsarin damar haɓaka amfani da wutar lantarki tare da saurin sarrafawa.

The Atmel AVR CPU ya haɗu da ingantaccen tsari na koyarwa tare da maƙasudin maƙasudin aiki guda 32. Dukkan rajista 32 suna da alaƙa kai tsaye zuwa sashin ilimin lissafi (ALU), yana ba da damar yin rajistar rajista masu zaman kansu guda biyu a cikin umarni ɗaya, waɗanda aka aiwatar a cikin agogo ɗaya. Sakamakon gine-ginen ya fi dacewa da lambobi yayin da ake samun abubuwan samarwa da yawa cikin sauri fiye da na al'ada-accumulator ko tushen microcontrollers na CISC.

Na'urorin AVR XMEGA A1U suna ba da fasalulluka masu zuwa: in-tsarin filasha mai shirye-shirye tare da damar karantawa-lokacin-rubutu; na ciki EEPROM da SRAM; Mai kula da DMA mai tashar tashoshi huɗu, tsarin taron tashoshi takwas da mai sarrafa katsewar matakan da yawa, 78 janar manufa I / O Lines, 16-bit real-time counter (RTC); takwas m, 16-bit timer/counters tare da kwatanta da tashoshi na PWM, USART guda takwas; hudu serial musaya (TWIs); daya cikakken gudun USB 2.0 dubawa; hudu serial peripheral interfaces (SPIs); AES da DES injin ƙira; CRC-16 (CRC-CCITT) da CRC-32 (IEEE 802.3) janareta; biyu 16-tashar, 12-bit ADCs tare da shirye-shirye riba; biyu 2-tashar, 12-bit DACs; Analog Comparators (ACs) guda huɗu tare da yanayin taga; mai ƙididdigewa mai ƙididdige lokaci mai tsaro tare da keɓantaccen oscillator na ciki; daidaitattun oscillators na ciki tare da PLL da prescaler; da gano launin ruwan kasa mai shirye-shirye.

Shirye-shiryen da keɓancewa (PDI), mai sauri, mai sauƙi mai rahusa biyu don shirye-shirye da cirewa, yana samuwa. Na'urorin kuma suna da IEEE std. 1149.1 mai jituwa JTAG interface, kuma wannan kuma ana iya amfani dashi don bincika iyaka, debug akan guntu da shirye-shirye.

Na'urorin XMEGA A1U suna da hanyoyin ceton wutar lantarki guda biyar. Yanayin aiki yana dakatar da CPU yayin da yake barin SRAM, mai sarrafa DMA, tsarin taron, mai sarrafa katsewa, da duk abin da ke kewaye don ci gaba da aiki. Yanayin saukar da wuta yana adana SRAM da yin rijistar abun ciki, amma yana dakatar da oscillators, yana kashe duk sauran ayyuka har sai TWI na gaba, ci gaba na USB, ko katsewar fil-canza, ko sake saitawa. A cikin yanayin adana wutar lantarki, ma'aunin asynchronous na ainihin lokacin yana ci gaba da gudana, yana barin aikace-aikacen ya kula da tushen lokacin lokacin da sauran na'urar ke barci. A cikin yanayin jiran aiki, oscillator crystal na waje yana ci gaba da gudana yayin da sauran na'urar ke barci. Wannan yana ba da damar farawa da sauri daga kristal na waje, haɗe tare da ƙarancin wutar lantarki. A cikin yanayin jiran aiki mai tsawo, duka babban oscillator da mai asynchronous mai ƙidayar lokaci suna ci gaba da gudana. Don ƙara rage amfani da wutar lantarki, ana iya dakatar da agogon gefe zuwa kowane na gefe ɗaya bisa zaɓi a yanayin aiki da yanayin bacci mara amfani.

Atmel yana ba da ɗakin karatu na QTouch kyauta don shigar da maɓallan taɓawa mai ƙarfi, faifai da ayyukan ƙafafun cikin na'urori masu sarrafa AVR.

Ana kera na'urar ta amfani da babban ɗigon Atmel, fasahar ƙwaƙwalwar ajiya mara canzawa. Za'a iya sake tsara žwažwalwar ajiyar filasha na shirin a cikin tsarin ta hanyar mu'amalar PDI ko JTAG. Mai ɗaukar kaya da ke aiki a cikin na'urar na iya amfani da kowane nau'i don saukar da shirin aikace-aikacen zuwa ƙwaƙwalwar filasha. The boot loader software a cikin boot flash sashe zai ci gaba da aiki yayin da ake sabunta sashin aikace-aikacen filasha, yana samar da aikin karantawa na gaskiya yayin rubutawa. Ta hanyar haɗa 8/16-bit RISC CPU tare da tsarin cikin-tsari, walƙiya mai sarrafa kansa, AVR XMEGA dangi ne mai ƙarfi na microcontroller wanda ke ba da mafita mai sauƙi da inganci don yawancin aikace-aikacen da aka haɗa.

Ana tallafawa duk na'urorin Atmel AVR XMEGA tare da cikakken tsarin shirye-shirye da kayan aikin haɓaka tsarin, gami da masu haɗawa da C, masu tarawa macro, debugger / na'urar kwaikwayo, masu shirye-shirye, da kayan ƙima.
