AT90CAN128-16AU IC MCU 8BIT 128KB IFLESHI 64TQFP

Inkcazo

I-AT90CAN32/64/128 sisilawuli esincinci se-CMOS esine-8-bit esekwe kwi-AVR eyandisiweyo yoyilo lwe-RISC.Ngokusebenzisa imiyalelo enamandla kumjikelo wewotshi enye, i-AT90CAN32/64/128 ifezekisa iziphumo ezisondela kwi-MIPS eyi-1 nge-MHz ivumela umyili wenkqubo ukuba andise ukusetyenziswa kwamandla ngokuchasene nesantya sokusetyenzwa.I-core ye-AVR idibanisa umyalelo ocebileyo kunye neerejista ze-32 eziqhelekileyo zokusebenza.Zonke iirejista ezingama-32 ziqhagamshelwe ngokuthe ngqo kwiYunithi ye-Arithmetic Logic (ALU), evumela iirejista ezimbini ezizimeleyo ukuba zifumaneke kumyalelo omnye owenziwe kumjikelo wewotshi enye.Ulwakhiwo olusisiphumo lusebenza ngakumbi ikhowudi ngelixa kuphunyezwa izinto ezidlulayo ukuya kuthi ga kalishumi ngokukhawuleza kunee-microcontrollers ze-CISC eziqhelekileyo.I-AT90CAN32/64/128 ibonelela ngezi mpawu zilandelayo: 32K/64K/128K bytes of In-System Programmable Flash enobuchule bokufunda-ngokubhala, 1K/2K/4K bytes EEPROM, 2K/4K/4K bytes SRAM, 53 injongo ngokubanzi Imigca ye-I / O, iirejista ze-32 eziqhelekileyo zokusebenza, umlawuli we-CAN, i-Real Time Counter (RTC), i-Timer eguquguqukayo emine / ii-Counters ezineendlela zokuthelekisa kunye ne-PWM, i-2 USARTs, i-byte ejoliswe kwi-byte ye-Two-wire Serial Interface, i-8-channel 10. I-bit ADC enenqanaba lokhetho lokhetho olukhethiweyo kunye nokuzuza okucwangcisiweyo, i-Watchdog Timer ecwangcisiweyo kunye ne-Oscillator yangaphakathi, i-SPI serial port, IEEE std.I-1149.1 ihambelana nojongano lovavanyo lwe-JTAG, ekwasetyenziselwa ukufikelela kwi-On-chip Debug system kunye neprogram kunye nesoftware ezintlanu ezikhethiweyo zokugcina amandla.Imodi ye-Idle imisa i-CPU ngelixa ivumela i-SRAM, i-Timer / Counters, i-SPI / izibuko ze-CAN kunye nenkqubo yokuphazamisa ukuqhubeka nokusebenza.Imowudi ye-Power-down igcina imixholo yerejista kodwa ifake i-Oscillator, ikhubaze yonke eminye imisebenzi ye-chip kude kube ukuphazamisa okulandelayo okanye Ukusethwa kwakhona kwe-Hardware.Kwimowudi yogcino lwamandla, isibali-xesha se-asynchronous siyaqhubeka nokusebenza, sivumela umsebenzisi ukuba agcine isiseko sesibali-xesha ngelixa sonke isixhobo silele.Imodi ye-ADC yokuNcitshiswa kweNxolo imisa i-CPU kunye nazo zonke iimodyuli ze-I / O ngaphandle kwe-Asynchronous Timer kunye ne-ADC, ukunciphisa ingxolo yokutshintsha ngexesha lokuguqulwa kwe-ADC.Kwimo yokulinda, iCrystal/Resonator Oscillator iyasebenza ngelixa sonke isixhobo silele.Oku kuvumela ukuqalisa ngokukhawuleza kakhulu kudityaniswe nokusetyenziswa kwamandla aphantsi.Esi sixhobo senziwa kusetyenziswa itekhnoloji yememori engaguquguqukiyo ephezulu ye-Atmel.I-Onchip ISP Flash ivumela imemori yeprogram ukuba iphinde ifakwe kwinkqubo ngokusebenzisa ujongano lwe-serial ye-SPI, ngumdwelisi wememori oqhelekileyo ongaguqukiyo, okanye ngenkqubo ye-On-chip Boot eqhuba kwi-AVR core.Inkqubo yokuqalisa inokusebenzisa naluphi na ujongano ukukhuphela inkqubo yesicelo kwimemori yesicelo seFlash.Isoftware ekwicandelo le-Boot Flash iya kuqhubeka isebenza ngelixa icandelo le-Aplikheyishini ye-Aplikheyishini lihlaziywa, libonelela ngokusebenza kokwenyani kokuFunda-Ngelixa-Bhala.
