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

Ibisobanuro

AT89C55WD nimbaraga nke, zikora cyane CMOS 8-bito ya microcontroller hamwe na 20K bytes ya Flash programable ishobora gusoma gusa kwibuka na 256 bytes ya RAM.Igikoresho cyakozwe hifashishijwe tekinoroji ya Atmel yubucucike bukabije kandi butajyanye ninganda zisanzwe 80C51 na 80C52 zashyizweho hamwe na pinout.Kuri chip Flash yemerera porogaramu yibuka kuba umukoresha wateguwe na progaramu isanzwe yibuka idafite imbaraga.Muguhuza ibice byinshi 8-bit CPU hamwe na Flash kuri chip ya monolithic, Atmel AT89C55WD ni microcomputer ikomeye itanga igisubizo cyoroshye kandi cyigiciro cyiza kubisubizo byinshi byashyizwe mubikorwa.AT89C55WD itanga ibiranga bisanzwe bikurikira: 20K bytes ya Flash, 256 bytes ya RAM, imirongo 32 I / O, imirongo itatu ya biti 16 / biti, ibice bitandatu, ibyiciro bitandatu byubatswe, ibyambu byombi byuzuye, kuri chip oscillator, hamwe nizunguruka ryamasaha.Mubyongeyeho, AT89C55WD yateguwe hamwe na logique ihagaze kugirango ikore kugeza kuri zeru kandi ishyigikira software ebyiri zatoranijwe zo kuzigama ingufu.Mode Idle ihagarika CPU mugihe yemerera RAM, ingengabihe / kubara, icyambu gikurikirana, hamwe na sisitemu yo guhagarika gukora.Uburyo bwa Power-down Mode ibika RAM ariko ikonjesha oscillator, igahagarika indi mirimo yose ya chip kugeza igihe ubutaha bwo guhagarika cyangwa gusubiramo ibyuma.
