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

Incazelo

I-AT89C55WD inamandla aphansi, i-CMOS 8-bit microcontroller esebenza kahle kakhulu enamabhayithi angu-20K we-Flash efundeka kalula inkumbulo namabhayithi angu-256 e-RAM.Idivayisi yakhiwe kusetshenziswa ubuchwepheshe bememori obungaguquki obuphezulu be-Atmel futhi ihambisana nezinga lemboni 80C51 kanye nesethi yemiyalo engu-80C52 kanye nokuphina.I-on-chip Flash ivumela imemori yohlelo ukuthi ibe ngumsebenzisi ehlelwe umhleli wememori ongaguquki.Ngokuhlanganisa i-CPU engu-8-bit ene-Flash ku-chip ye-monolithic, i-Atmel AT89C55WD iyikhompyutha encane enamandla ehlinzeka ngesixazululo esivumelana nezimo kakhulu nesibizayo ezinhlelweni eziningi zokulawula ezishumekiwe.I-AT89C55WD ihlinzeka ngezici ezijwayelekile ezilandelayo: amabhayithi angu-20K eFlash, amabhayithi angu-256 e-RAM, imigqa engu-32 I/O, i-timer/counter emithathu engu-16-bit, i-six-vector, i-architecture ephazamisayo enamazinga amabili, imbobo ye-serial ephelele eyiduplex, i-on-chip oscillator, nokujikeleza kwewashi.Ngaphezu kwalokho, i-AT89C55WD yakhelwe nge-logic emile ukuze isebenze kuze kufike ku-zero frequency futhi isekela izindlela ezimbili zokonga amandla ezikhethekayo.I-Idle Mode imisa i-CPU ngenkathi ivumela i-RAM, isibali sikhathi/izibali, imbobo yochungechunge, kanye nesistimu yokuphazamisa ukuthi iqhubeke nokusebenza.I-Power-down Mode ilondoloza okuqukethwe kwe-RAM kodwa imise i-oscillator, ivimbele yonke eminye imisebenzi ye-chip kuze kube ukuphazamisa kwangaphandle okulandelayo noma ukusethwa kabusha kwehadiwe.
