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

wehewehe

ʻO ka AT89C55WD kahi microcontroller CMOS 8-bit haʻahaʻa haʻahaʻa me 20K bytes o Flash programmable read memory a me 256 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 ʻoihana maʻamau 80C51 a me 80C52 hoʻonohonoho aʻo 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.Ma ka hoʻohui ʻana i kahi CPU 8-bit maʻalahi me Flash ma kahi chip monolithic, ʻo ka Atmel AT89C55WD kahi microcomputer ikaika e hāʻawi i kahi hopena maʻalahi a maikaʻi hoʻi i nā noi mana hoʻopili.Hāʻawi ka AT89C55WD i kēia mau hiʻohiʻona maʻamau: 20K bytes o Flash, 256 bytes o RAM, 32 I/O laina, ʻekolu 16-bit timer/counters, ʻeono-vector, ʻelua-level interrupt architecture, full-duplex serial port, on-chip oscillator, a me ka uaki kaapuni.Eia kekahi, ua hoʻolālā ʻia ka AT89C55WD 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 ka Power-down Mode i nā mea 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 hoʻonohonoho ʻana i ka lako.
