Whakaahuatanga
Ko te matua Atmel®AVR® he whakakotahi i te huinga tohutohu whai kiko me nga rehita mahi 32.Ko nga rehita 32 katoa e hono tika ana 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 ATmega8 nga ahuatanga e whai ake nei: 8 Kbytes o In-System Programmable Flash with Read-While-Write capabilities, 512 bytes of EEPROM, 1 Kbyte of SRAM, 23 general purpose I/O lines, 32 general purpose working registers, toru flexible Timer /Kaitatau he whakataurite aratau, he haukoti o roto, o waho hoki, he USART ka taea te whakahoahoa, he paita-a-roto a Twowire Serial Interface, he ADC 6-hongere (e waru nga hongere i roto i nga kohinga TQFP me te QFN/MLF) me te tika moka-10, he Kaitiaki Tiaki ka taea te whakarite. Oscillator o roto, he tauranga rangatū SPI, me nga aratau whakaora hiko e rima ka taea te whiriwhiri.Ko te aratau Idle ka aukati i te PTM i te wa e tuku ana te SRAM, Timer/Kaitatau, te tauranga SPI, me te punaha haukoti kia mahi tonu.Ko te aratau Powerdown ka tiaki i nga ihirangi rehita engari ka whakatio i te Oscillator, ka whakakore i nga mahi maramara katoa kia tae ra ano ki te Whakamotitia me te Tautuhi-Tautuhi-a-Maama.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 tukutahi me te ADC, hei whakaiti i te haruru whakawhiti i nga huringa ADC.I roto i te aratau Standby, kei te rere te Oscillator tioata/resonator i te wa e moe ana te toenga o te taputapu.Ma tenei ka tino tere te tiimata me te kohi hiko iti.
