Chithunzi cha AT89S52-24AU IC MCU 8BIT 8KB FLASH 44TQFP

Kufotokozera

AT89S52 ndi yamphamvu yotsika, yogwira ntchito kwambiri ya CMOS 8-bit microcontroller yokhala ndi ma 8K bytes a in-system programmable Flash memory.Chipangizochi chimapangidwa pogwiritsa ntchito ukadaulo waukadaulo wa Atmel's high-density nonvolatile memory ndipo umagwirizana ndi malangizo amakampani a 80C51 ndi pinout.The on-chip Flash imalola kuti kukumbukira kwa pulogalamuyo kukonzedwenso mkati mwadongosolo kapena ndi pulogalamu yanthawi yayitali yosasinthika.Pophatikiza 8-bit CPU yosunthika yokhala ndi Flash yokhazikika pa chipangizo cha monolithic, Atmel AT89S52 ndi chowongolera champhamvu chomwe chimapereka yankho losinthika komanso lotsika mtengo pamapulogalamu ambiri ophatikizidwa.AT89S52 imapereka mawonekedwe awa: 8K byte of Flash, 256 bytes of RAM, 32 I/O mizere, Watchdog timer, zolozera deta ziwiri, 16-bit timer/counters, zomangamanga zisanu ndi chimodzi zamagawo awiri, a doko lathunthu la duplex serial, on-chip oscillator, ndi mawotchi ozungulira.Kuphatikiza apo, AT89S52 idapangidwa ndi malingaliro osasunthika kuti igwire ntchito mpaka zero pafupipafupi ndipo imathandizira mitundu iwiri yosankha yopulumutsira mphamvu yamapulogalamu.Idle Mode imayimitsa CPU kwinaku ikulola RAM, timer/counters, serial port, and interrupt system kuti ipitilize kugwira ntchito.Mawonekedwe a Power-down amasunga zomwe zili mu RAM koma amaundana oscillator, kulepheretsa ntchito zina zonse za chip mpaka kusokoneza kwina kapena kukonzanso kwa hardware.
