Kev piav qhia
AT89C51RC yog lub zog qis, ua haujlwm siab CMOS 8-ntsis microcontroller nrog 32K bytes ntawm Flash programmable nyeem nkaus xwb nco thiab 512 bytes ntawm RAM.Cov cuab yeej yog tsim los ntawm Atmel's high-density nonvolatile memory technology 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.Tag nrho ntawm 512 bytes ntawm RAM sab hauv muaj nyob rau hauv AT89C51RC.Lub 256-byte nthuav dav hauv RAM yog nkag los ntawm MOVX cov lus qhia tom qab tshem me ntsis 1 hauv SFR nyob ntawm qhov chaw nyob 8EH.Lwm 256-byte RAM ntu tau nkag mus tib yam li Atmel AT89-series thiab lwm yam khoom siv 8052-tshaj.Los ntawm kev sib txuas ua ke ntau yam 8-ntsis CPU nrog Flash ntawm cov nti monolithic, Atmel AT89C51RC yog lub microcomputer muaj zog uas muab cov kev daws teeb meem zoo thiab raug nqi rau ntau daim ntawv thov kev tswj hwm.AT89C51RC muab cov qauv hauv qab no: 32K bytes ntawm Flash, 512 bytes ntawm RAM, 32 I / O kab, peb 16-ntsis timer / txee, rau-vector ob-theem cuam tshuam architecture, tag nrho duplex serial chaw nres nkoj, on- chip oscillator, thiab moos circuitry.Tsis tas li ntawd, AT89C51RC 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 ntawm RAM tab sis khov lub oscillator, disabling tag nrho lwm cov nti ua haujlwm kom txog rau thaum lwm qhov cuam tshuam los yog kho vajtse pib dua.
