Kev piav qhia
AT89C55WD yog lub zog qis, ua haujlwm siab CMOS 8-ntsis microcontroller nrog 20K bytes ntawm Flash programmable nyeem tsuas yog nco thiab 256 bytes ntawm RAM.Cov cuab yeej yog tsim los ntawm Atmel's high-density nonvolatile nco tshuab thiab yog sib xws nrog kev lag luam tus qauv 80C51 thiab 80C52 kev qhia teeb thiab pinout.Lub on-chip Flash tso cai rau qhov kev pab cuam nco yog cov neeg siv programmed los ntawm ib qho kev ua haujlwm tsis zoo ntawm lub cim xeeb.Los ntawm kev sib txuas ua ke ntau yam 8-ntsis CPU nrog Flash ntawm lub monolithic nti, Atmel AT89C55WD yog lub microcomputer muaj zog uas muab cov kev daws teeb meem zoo heev thiab raug nqi rau ntau daim ntawv thov kev tswj hwm.AT89C55WD muab cov qauv hauv qab no: 20K bytes ntawm Flash, 256 bytes ntawm RAM, 32 I / O kab, peb 16-ntsis timer / counters, rau-vector, ob-theem cuam tshuam architecture, full-duplex serial chaw nres nkoj, on-chip oscillator, thiab moos circuitry.Tsis tas li ntawd, AT89C55WD yog tsim los nrog cov logic zoo li qub rau kev ua haujlwm mus rau xoom zaus thiab txhawb nqa ob lub software xaiv lub zog txuag hom.Hom Idle nres lub CPU thaum tso cai rau RAM, timer / counters, serial chaw nres nkoj, thiab cuam tshuam qhov system txuas ntxiv ua haujlwm.Lub Hwj Chim-down hom txuag cov ntsiab lus RAM tab sis khov lub oscillator, cuam tshuam tag nrho lwm cov nti ua haujlwm kom txog thaum lwm qhov cuam tshuam sab nraud lossis kho vajtse pib dua.
