AT89S52-24PU IC MCU 8BIT 8KB FLASH 40 DIP

wehewehe

ʻO ka AT89S52 kahi microcontroller 8-bit CMOS haʻahaʻa haʻahaʻa me 8K bytes o ka hoʻomanaʻo Flash programmable i loko o ka ʻōnaehana.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 maʻamau a me ka pinout.Hiki i ka Flash on-chip ke hoʻoponopono hou ʻia ka hoʻomanaʻo o ka papahana i loko o ka ʻōnaehana a i ʻole e kahi mea hoʻomanaʻo hoʻomanaʻo nonvolatile maʻamau.Ma ka hoʻohui ʻana i kahi CPU 8-bit maʻalahi me ka Flash programmable in-system ma kahi chip monolithic, ʻo ka Atmel AT89S52 kahi microcontroller ikaika e hāʻawi ana i kahi hopena maʻalahi a me ke kumu kūʻai i nā noi mana hoʻopili.Hāʻawi ka AT89S52 i kēia mau hiʻohiʻona maʻamau: 8K bytes o Flash, 256 bytes RAM, 32 mau laina I/O, Watchdog timer, ʻelua mau kuhikuhi ʻikepili, ʻekolu 16-bit timer/counters, ʻeono-vector two-level interrupt architecture, a piha duplex serial port, on-chip oscillator, a me ka uaki kaapuni.Eia hou, ua hoʻolālā ʻia ka AT89S52 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 hou ʻana a i ʻole ka hoʻoponopono ʻana i ka lako.
