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

Sharaxaada

AT89C55WD waa awood hoose, wax qabad sare oo CMOS 8-bit microcontroller ah oo leh 20K bytes ee Flash programmable read only memory iyo 256 bytes of RAM.Qalabka waxaa lagu soo saaray iyadoo la adeegsanayo tignoolajiyada xusuusta ee cufnaanta sare ee Atmel waxayna la jaan qaadaysaa heerka warshadaha ee 80C51 iyo 80C52 set iyo pinout.Flash-ku-shiilku waxa uu u oggolaanayaa in xusuusta barnaamijka ay noqoto mid uu isticmaalo barnaamij-sameeyaha xusuusta aan isbeddelayn ee caadiga ah.Marka la isku daro 8-bit CPU oo isku dhafan oo leh Flash on chip monolithic, Atmel AT89C55WD waa microcomputer awood leh kaas oo siinaya xal aad u dabacsan oo qiimo leh oo wax ku ool ah codsiyo badan oo xakameyn ah.AT89C55WD waxay bixisaa sifooyinka caadiga ah ee soo socda: 20K bytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timemer/counters, a six-vector, two level architecture architecture, a full-duplex serial port, on-chip oscillator, iyo wareegga saacada.Intaa waxaa dheer, AT89C55WD waxaa loogu talagalay iyadoo leh macquul macquul ah oo loogu talagalay hawlgalka ilaa inta jeer ee eber waxayna taageertaa laba software oo la dooran karo hababka badbaadinta awoodda.Qaabka shaqo la'aanta ahi wuxuu joojiyaa CPU-ga isagoo u oggolaanaya RAM-ka, saacada/counter-yada, dekedda taxanaha ah, iyo nidaamka kala-goynta inuu sii shaqeeyo.Habka Power-down-ka wuxuu badbaadiyaa waxa ku jira RAM laakiin wuxuu qaboojiyaa oscillator-ka, wuxuu curyaamiyaa dhammaan hawlaha kale ee chip-ka illaa inta dib-u-dejinta dibadda ee soo socota ama dib-u-dejinta qalabka.
