AT89C51RC-24AU IC MCU 8BIT 32KB MAHI 44TQFP

Whakaahuatanga

Ko te AT89C51RC he mana iti-mana, teitei-mahi CMOS 8-bit microcontroller me te 32K paita o te Flash mahara panui-anake ka taea te papatono me te 512 paita o te RAM.Ka hangaia te taputapu ma te whakamahi i te hangarau mahara kore puhoi a Atmel me te hototahi ki te paerewa-ahumahi 80C51 me te 80C52 huinga tohutohu me te pinout.Ka taea e te Flash maramara runga te mahara o te hotaka kia hotaka e te kaihōtaka mahara kore-kore.He 512 paita katoa o te RAM o roto kei te AT89C51RC.Ko te 256-paita kua whakawhānuihia te RAM o roto ka uru atu ma nga tohutohu MOVX i muri i te whakakore i te moka 1 i te SFR kei te wahitau 8EH.Ko etahi atu waahanga 256-byte RAM e uru ana ki te huarahi rite ki te Atmel AT89-raupapa me etahi atu hua 8052-hototahi.Ma te whakakotahi i te PTM 8-bit me te Flash i runga i te maramara monolithic, ko te Atmel AT89C51RC he miihini miihini kaha e whakarato ana i te otinga tino ngawari me te utu ki te maha o nga tono mana whakauru.Ka whakaratohia e te AT89C51RC nga ahuatanga paerewa e whai ake nei: 32K paita o Flash, 512 paita o RAM, 32 I/O raina, toru moka-16 matawā/counters, he ono-vector rua-taumata hanganga haukoti, he tauranga rangatū matarua katoa, on- oscillator maramara, me te ara iahiko karaka.I tua atu, kua hoahoatia te AT89C51RC me te arorau pateko mo te mahi ki raro ki te kore auau me te tautoko i nga momo momo whakaora hiko e rua ka taea te kowhiri.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 tiakina nga ihirangi RAM engari ka whakatio i te oscillator, ka whakakore i nga mahi maramara katoa tae noa ki te aukati o waho o muri mai, ki te tautuhi taputapu ranei.
