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

wehewehe

ʻO ka AT89C51RC kahi microcontroller CMOS 8-bit haʻahaʻa haʻahaʻa me 32K bytes o Flash programmable read-only memory a me 512 bytes o RAM.Hana ʻia ka hāmeʻa me ka hoʻohana ʻana i ka ʻenehana hoʻomanaʻo nonvolatile kiʻekiʻe kiʻekiʻe o Atmel a ua kūpono me ka hoʻonohonoho aʻoaʻo 80C51 a me 80C52 maʻamau a me ka pinout.Hiki i ka Flash on-chip ke hoʻohana i ka hoʻomanaʻo o ka papahana i hoʻolālā ʻia e kahi mea hoʻomanaʻo hoʻomanaʻo nonvolatile maʻamau.Loaʻa ka huina o 512 bytes o RAM i loko o ka AT89C51RC.Loaʻa ka 256-byte i hoʻonui ʻia i loko o ka RAM ma o nā ʻōlelo kuhikuhi MOVX ma hope o ka hoʻomaʻemaʻe ʻana i ka bit 1 ma ka SFR aia ma ka helu 8EH.Loaʻa ka ʻāpana 256-byte RAM ʻē aʻe i ke ala like me ka Atmel AT89-series a me nā huahana 8052-like.Ma ka hoʻohui ʻana i kahi CPU 8-bit maʻalahi me Flash ma kahi chip monolithic, ʻo ka Atmel AT89C51RC kahi microcomputer ikaika e hāʻawi i kahi hopena maʻalahi a maikaʻi hoʻi i nā noi mana hoʻopili.Hāʻawi ka AT89C51RC i kēia mau hiʻohiʻona maʻamau: 32K bytes o Flash, 512 bytes RAM, 32 I/O laina, ʻekolu 16-bit timer/counters, ʻeono-vector ʻelua-level interrupt architecture, piha duplex serial port, ma- chip oscillator, a me ka uaki kaapuni.Eia kekahi, ua hoʻolālā ʻia ka AT89C51RC me ka loiloi static no ka hana ʻana a hiki i ka zero frequency a kākoʻo i ʻelua mau polokalamu 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 Power-down i ka ʻike o ka RAM akā hoʻokuʻu i ka oscillator, hoʻopau i nā hana chip ʻē aʻe a hiki i ka hoʻopau ʻana o waho a i ʻole ka hoʻoponopono ʻana i ka lako.
