AT89C55WD-24PU IC MCU 8BIT 20KB MAHI 40DIP

Whakaahuatanga

Ko te AT89C55WD he mana iti-kaha, teitei-mahi CMOS 8-bit microcontroller ki 20K paita o Flash programmable pānui anake mahara me te 256 paita o 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.Ma te whakakotahi i te PTM 8-bit me te Flash i runga i te maramara monolithic, ko te Atmel AT89C55WD he rorohiko moroiti kaha e whakarato ana i te otinga tino ngawari me te utu ki te maha o nga tono whakahaere whakauru.Ko te AT89C55WD e whakarato ana i nga ahuatanga paerewa e whai ake nei: 20K paita o Flash, 256 paita o RAM, 32 nga raina I/O, e toru 16-bit matawā/counters, he ono-vector, hoahoanga haukoti taumata-rua, he tauranga rangatū-rua-rua, oscillator on-chip, me te ara iahiko karaka.I tua atu, i hangaia te AT89C55WD 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.Ka tiakina e te Aratau Whakararo nga ihirangi RAM engari ka whakatio i te oscillator, ka whakakore i nga mahi maramara katoa tae noa ki te aukati o waho, ki te tautuhi taputapu ranei.
