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

Incazelo

I-AT90CAN32/64/128 iyi-CMOS 8-bit microcontroller enamandla aphansi esekelwe ekwakhiweni kwe-AVR okuthuthukisiwe kwe-RISC.Ngokusebenzisa iziqondiso ezinamandla kumjikelezo wewashi elilodwa, i-AT90CAN32/64/128 ifinyelela imiphumela esondela ku-1 MIP nge-MHz ngayinye evumela umklami wesistimu ukuthi athuthukise ukusetshenziswa kwamandla ngokumelene nesivinini sokucubungula.Umongo we-AVR uhlanganisa isethi yemiyalo ecebile namarejista okusebenza ngezinjongo ezijwayelekile ezingu-32.Wonke amarejista angama-32 axhumeke ngokuqondile ku-Arithmetic Logic Unit (ALU), okuvumela amarejista amabili azimele ukuthi afinyelelwe emyalezweni owodwa owenziwe ngomjikelezo wewashi owodwa.Isakhiwo esiwumphumela sisebenza kahle kakhulu ngekhodi kuyilapho sizuza okuphumayo ngokushesha okuphindwe kashumi kunezilawuli ezincane ezivamile ze-CISC.I-AT90CAN32/64/128 inikeza izici ezilandelayo: amabhayithi angu-32K/64K/128K e-In-System Programmable Flash enamandla okufunda-Ngenkathi-Bhala, amabhayithi angu-1K/2K/4K EEPROM, amabhayithi angu-2K/4K/4K SRAM, inhloso evamile engu-53 Imigqa ye-I/O, amarejista okusebenza ezinjongo ezijwayelekile ezingu-32, isilawuli se-CAN, I-Real Time Counter (RTC), I-Timer/Counters ezine eziguquguqukayo ezinamamodi okuqhathanisa kanye ne-PWM, 2 USARTs, i-byte enama-byte e-Two-wire Serial Interface, i-8-channel 10 -bit ADC enesiteji sokufaka esikhethekile esinenzuzo ehlelekayo, i-Watchdog Timer ehlelekayo ene-Internal Oscillator, i-SPI serial port, IEEE std.1149.1 isixhumi esibonakalayo sokuhlola se-JTAG esithobelanayo, siphinde sisetshenziselwe ukufinyelela isistimu ye-On-chip Debug kanye nezinhlelo kanye nezindlela ezinhlanu zokulondoloza amandla ezikhethekayo zesofthiwe.Imodi yokungenzi lutho imisa i-CPU ngenkathi ivumela i-SRAM, Isikhathi/Izibali, izimbobo ze-SPI/CAN kanye nesistimu ephazamisayo ukuthi iqhubeke nokusebenza.Imodi ye-Power-down igcina okuqukethwe kwerejista kodwa imise i-Oscillator, ikhubaze yonke eminye imisebenzi ye-chip kuze kube ukuphazamisa okulandelayo noma Ukusethwa Kabusha kwe-Hardware.Kumodi yokonga amandla, isibali sikhathi esivumelanayo siyaqhubeka nokusebenza, sivumela umsebenzisi ukuthi agcine isisekelo sesibali sikhathi ngenkathi yonke idivayisi ilele.Imodi yokunciphisa umsindo ye-ADC imisa i-CPU nawo wonke amamojula e-I/O ngaphandle kwe-Asynchronous Timer ne-ADC, ukuze kuncishiswe umsindo oshintshayo phakathi nokuguqulwa kwe-ADC.Kumodi yokulinda, i-Crystal/Resonator Oscillator iyasebenza ngenkathi yonke idivayisi ilele.Lokhu kuvumela ukuqalisa okusheshayo kuhlanganiswe nokusetshenziswa kwamandla okuphansi.Idivayisi yakhiwe kusetshenziswa ubuchwepheshe bememori obungaguquki obuphezulu be-Atmel.I-Onchip ISP Flash ivumela inkumbulo yohlelo ukuthi ihlelwe kabusha ohlelweni ngokusebenzisa isixhumi esibonakalayo se-SPI, ngohlelo oluvamile lwememori olungaguquki, noma ngohlelo lwe-On-chip Boot olusebenza kumongo we-AVR.Uhlelo lokuqalisa lungasebenzisa noma yisiphi isikhombimsebenzisi ukulanda uhlelo lohlelo lokusebenza kumemori ye-Flash yesicelo.Isofthiwe esigabeni se-Boot Flash izoqhubeka nokusebenza ngenkathi isigaba se-Flash Yohlelo sisabuyekezwa, sihlinzeka ngokusebenza kwangempela kwe-Read-While-Write.
