Whakaahuatanga
Ko te AT90CAN32/64/128 he mana iti CMOS 8-bit microcontroller i runga i te AVR whakarei RISC hoahoanga.Ma te whakahaere i nga tohutohu kaha i roto i te huringa karaka kotahi, ka tutuki te AT90CAN32/64/128 i nga waahanga e tata ana ki te 1 MIPS ia MHz ka taea e te kaihoahoa punaha te arotau i te kohi hiko me te tere tukatuka.Ko te matua AVR he whakakotahi i tetahi huinga tohutohu whai kiko me nga rehita mahi e 32.Ka hono katoa nga rehita 32 ki te Arithmetic Logic Unit (ALU), kia rua nga rehita motuhake e uru ki roto i te ako kotahi ka mahia i roto i te huringa karaka kotahi.He pai ake te tohu o te hoahoanga i te wa e eke ana nga hua ki te tekau nga wa tere atu i nga microcontrollers CISC tikanga.Kei te AT90CAN32/64/128 nga ahuatanga e whai ake nei: 32K/64K/128K paita o In-System Programmable Flash with Read-While-Write capabilities, 1K/2K/4K bytes EEPROM, 2K/4K/4K bytes SRAM, 53 kaupapa whānui Ko nga raina I/O, 32 nga rehita mahi kaupapa whanui, he kaiwhakahaere CAN, Kaitatau Wa Tuturu (RTC), e wha nga Kaitauta Waea ngawari me nga momo whakataurite me te PWM, 2 USARTs, he paita atanga Atanga Rangatū Waea-rua, he hongere 8 10 -bit ADC me te waahanga whakauru rereke rereke me te taonga ka taea te whakarite, he Kaitiaki Kaitirotiro ka taea te whakarite me te Oscillator Roo, he tauranga rangatū SPI, IEEE std.1149.1 te atanga whakamatautau JTAG, i whakamahia hoki mo te uru atu ki te punaha Patuiro-Maihini me te hotaka me nga momo raupaparorohiko e rima ka taea te penapena hiko.Ko te aratau Idle ka aukati i te PTM i te wa e tuku ana te SRAM, Timer/Kaitatau, SPI/CAN tauranga me te punaha haukoti kia mahi tonu.Ko te aratau Hiko-iho ka tiaki i nga ihirangi rehita engari ka whakatio i te Oscillator, ka whakakore i nga mahi maramara katoa tae noa ki te haukoti o muri mai, ki te Tautuhi-a-Tautuhi-a-Maama ranei.I roto i te aratau Tiaki-Hiko, ka haere tonu te taima tukutahi, ka taea e te kaiwhakamahi te pupuri i te turanga matawā i te wa e moe ana te toenga o te taputapu.Ko te ADC Noise Reduction Reduction ka aukati i te PTM me nga waahanga I/O katoa engari ko te Matama Asynchronous me te ADC, hei whakaiti i te ngangau whakawhiti i nga huringa ADC.I te aratau Standby, kei te rere te Crystal/Resonator Oscillator i te wa e moe ana te toenga o te taputapu.Ma tenei ka tino tere te tiimata me te iti o te kohi hiko.Ka hangaia te taputapu ma te whakamahi i te hangarau mahara kore puhoi a Atmel.Ka taea e te Onchip ISP Flash te whakamaumaharatanga o te hotaka i roto i te punaha na roto i te atanga rangatū SPI, na te kaitoha mahara kore-kore noa, na te kaupapa Boot On-chip ranei e rere ana i runga i te AVR matua.Ka taea e te kaupapa whawhai te whakamahi i tetahi atanga ki te tango i te papatono tono i roto i te mahara Flash tono.Ko nga raupaparorohiko kei te waahanga Boot Flash ka haere tonu i te wa e whakahouhia ana te waahanga Taupānga Flash, e whakarato ana i te mahi Panui-Ahakoa-Tuhituhi pono.
