ʻO ka AT89C4051 kahi microcontroller CMOS 8-bit kiʻekiʻe me 4K bytes o Flash programmable a holoi ʻia me ka hoʻomanaʻo heluhelu wale nō.Hana ʻia ka hāmeʻa me ka hoʻohana ʻana i ka ʻenehana hoʻomanaʻo nonvolatile kiʻekiʻe kiʻekiʻe o Atmel a ua kūpono me ka hoʻonohonoho aʻoaʻo MCS-51 maʻamau.Ma ka hoʻohui ʻana i kahi CPU 8-bit maʻalahi me Flash ma kahi chip monolithic, ʻo ka Atmel AT89C4051 kahi microcontroller ikaika e hāʻawi ana i kahi hopena maʻalahi a maikaʻi hoʻi i nā noi mana hoʻopili.Hāʻawi ka AT89C4051 i kēia mau hiʻohiʻona maʻamau: 4K bytes o Flash, 128 bytes RAM, 15 mau laina I/O, ʻelua 16-bit timer/counters, ʻelima-vector, ʻelua-level interrupt architecture, kahi duplex serial port, a mea hoʻohālikelike analog pololei, oscillator on-chip a me ka uaki kaapuni.Eia kekahi, ua hoʻolālā ʻia ka AT89C4051 me ka loiloi static no ka hana ʻana a hiki i ka zero frequency a kākoʻo i ʻelua mau ʻano hoʻopakele mana koho.Hoʻopau ke ʻano Idle i ka CPU ʻoiai e ʻae ana i ka RAM, timer / counters, serial port a me ka ʻōnaehana interrupt e hoʻomau i ka hana.Mālama ke ʻano mana iho i ka ʻike o ka RAM akā hoʻokuʻu i ka oscillator e hoʻopau i nā hana chip ʻē aʻe a hiki i ka hoʻonohonoho hou ʻana o ka lako.
