Whakaahuatanga
Ko te AT89S52 he miihini iti-kaha, he mahi teitei CMOS 8-bit microcontroller me te 8K paita o te mahara Flash e taea ana e te punaha.Ka hangaia te taputapu ma te whakamahi i te hangarau mahara kore puhoi-nui a Atmel me te hototahi ki te huinga tohutohu 80C51 paerewa-ahumahi me te pinout.Ma te maramara Flash ka taea te mahara o te papatono ki te whakahoahoa i roto i te punaha, i tetahi kaihataka mahara kore puhoi.Ma te whakakotahi i te PTM 8-bit whai kiko me te Flash ka taea e te punaha i runga i te maramara monolithic, ko te Atmel AT89S52 he microcontroller kaha e whakarato ana i te otinga tino ngawari me te utu ki te maha o nga tono whakahaere whakauru.Ko te AT89S52 e whakarato ana i nga ahuatanga paerewa e whai ake nei: 8K paita o Flash, 256 paita o te RAM, 32 I/O nga raina, Mataima Watchdog, e rua nga tohu tohu raraunga, e toru 16-bit matawā/counters, he ono-vector rua-taumata hanganga haukoti, he tauranga rangatū matarua katoa, oscillator i runga maramara, me te ara iahiko karaka.I tua atu, kua hoahoatia te AT89S52 me te arorau pateko mo te mahi ki raro ki te kore auau me te tautoko i nga momo momo whakaora hiko e rua.Ko te Aratau Idle ka aukati i te PTM i te wa e tuku ana te RAM, te taima/counter, te tauranga rangatū, me te punaha haukoti kia mahi tonu.Ko te aratau Hiko-iho ka tiaki i nga ihirangi RAM engari ka whakatio i te oscillator, ka whakakore i nga mahi maramara katoa tae noa ki te aukati i muri mai, te tautuhi taputapu ranei.
