AT89C2051-24PU IC MCU 8BIT 2KB FLASH 20DIP

Whakaahuatanga

Ko te AT89C2051 he iti-ngaohiko, teitei-mahi CMOS moka-8 rorohiko me te 2K paita o Flash ka taea te papatono me te whakakore i te mahara panui-anake (PEROM).Ka hangaia te taputapu ma te whakamahi i te hangarau mahara kore puhoi a Atmel me te hototahi ki te huinga tohutohu MCS-51 paerewa-ahumahi.Ma te whakakotahi i te PTM 8-bit me te Flash i runga i te maramara monolithic, ko te Atmel AT89C2051 he miihini miihini kaha e whakarato ana i te otinga tino ngawari me te utu ki te maha o nga tono mana whakauru.Ko te AT89C2051 e whakarato ana i nga ahuatanga paerewa e whai ake nei: 2K paita o Flash, 128 paita o te RAM, 15 nga raina I/O, e rua 16-bit matawā/counters, he vector rua-taumata haukoti hoahoanga, he tauranga rangatū matarua katoa, he tairitenga tika. kaiwhakariterite, oscillator i runga maramara me te ara iahiko karaka.I tua atu, kua hangaia te AT89C2051 me te arorau pateko mo te mahi ki raro ki te kore auau me te tautoko e rua nga raupaparorohiko ka taea te kowhiri i nga momo penapena hiko.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 whakaheke-hiko ka whakaora i nga ihirangi RAM engari ka whakatio te oscillator ki te whakakore i nga mahi maramara katoa tae noa ki te tautuhi taputapu ka whai ake.
