Chithunzi cha AT90CAN128-16AU IC MCU 8BIT 128KB FLASH 64TQFP

Kufotokozera

AT90CAN32/64/128 ndi chowongolera chochepa champhamvu cha CMOS 8-bit kutengera kamangidwe ka AVR kopititsa patsogolo ka RISC.Pogwiritsa ntchito malangizo amphamvu pawotchi imodzi, AT90CAN32/64/128 imakwaniritsa zodutsa zomwe zikuyandikira 1 MIPS pa MHz zomwe zimalola wopanga makinawo kukhathamiritsa kugwiritsa ntchito mphamvu poyerekeza ndi liwiro la kukonza.AVR pachimake amaphatikiza malangizo olemera okhala ndi zolembera 32 zogwirira ntchito.Ma regista onse 32 amalumikizidwa mwachindunji ndi Arithmetic Logic Unit (ALU), kulola zolembetsa ziwiri zodziyimira pawokha kuti zipezeke mu malangizo amodzi omwe amaperekedwa munthawi imodzi.Zomangamanga zomwe zimapangidwira zimakhala zogwira mtima kwambiri pamene zikugwira ntchito mpaka khumi mofulumira kuposa ma microcontrollers wamba a CISC.AT90CAN32/64/128 ili ndi izi: 32K/64K/128K ma byte a In-System Programmable Flash yokhala ndi luso la Kuwerenga-Polemba, 1K/2K/4K ma byte EEPROM, 2K/4K/4K ma byte SRAM, 53 cholinga chonse Mizere ya I/O, ma regista 32 ogwirira ntchito, chowongolera cha CAN, Real Time Counter (RTC), Zowerengera / Zowerengera zosinthika zinayi zokhala ndi mitundu yofananira ndi PWM, 2 USARTs, ma byte olunjika pa Two-waya Serial Interface, 8-channel 10 -bit ADC yokhala ndi gawo lolowera losankha lokhala ndi phindu lokonzekera, Watchdog Timer yokhala ndi Internal Oscillator, SPI serial port, IEEE std.1149.1 yogwirizana ndi JTAG yoyeserera, yomwe imagwiritsidwanso ntchito pofikira pa On-chip Debug system ndi mapologalamu ndi mitundu isanu yosankha yosungira mphamvu.Idle mode imayimitsa CPU kwinaku ikulola ma SRAM, Timer/Counters, madoko a SPI/CAN ndi makina osokoneza kuti apitilize kugwira ntchito.Njira ya Power-down imasunga zomwe zili m'kaundula koma imayimitsa Oscillator, kulepheretsa ntchito zina zonse za chip mpaka kusokoneza kwina kapena Hardware Bwezerani.Munjira yosungira Mphamvu, chowerengera cha asynchronous chikupitiliza kuthamanga, kulola wogwiritsa ntchito kusunga nthawi pomwe chipangizocho chikugona.ADC Noise Reduction mode imayimitsa CPU ndi ma modules onse a I / O kupatula Asynchronous Timer ndi ADC, kuti achepetse phokoso losintha panthawi ya ADC.Mumayendedwe oyimilira, Crystal/Resonator Oscillator ikugwira ntchito pomwe zida zonse zikugona.Izi zimalola kuyambitsa mwachangu kwambiri kuphatikiza ndi kugwiritsa ntchito mphamvu zochepa.Chipangizochi chimapangidwa pogwiritsa ntchito ukadaulo wa Atmel's high-density nonvolatile memory.Kung'anima kwa Onchip ISP kumapangitsa kuti kukumbukira kwa pulogalamuyo kukonzedwenso m'dongosolo kudzera mu mawonekedwe amtundu wa SPI, ndi pulogalamu yanthawi yayitali yosasinthika, kapena pulogalamu ya On-chip Boot yomwe ikuyenda pa AVR core.Pulogalamu ya boot imatha kugwiritsa ntchito mawonekedwe aliwonse kutsitsa pulogalamu yogwiritsira ntchito mu Flash memory.Mapulogalamu omwe ali mugawo la Boot Flash apitiliza kugwira ntchito pomwe gawo la Application Flash likusinthidwa, ndikupereka ntchito yeniyeni ya Read-While-Write.
