Kev piav qhia
AT89S52 yog lub zog qis, ua haujlwm siab CMOS 8-ntsis microcontroller nrog 8K bytes ntawm hauv-system programmable Flash nco.Cov cuab yeej yog tsim los ntawm Atmel's high-density nonvolatile memory technology thiab tau sib xws nrog kev lag luam-tus qauv 80C51 kev qhia teeb thiab pinout.Lub on-chip Flash tso cai rau cov kev pab cuam nco tau reprogrammed nyob rau hauv-system los yog los ntawm ib tug pa nonvolatile nco programmer.Los ntawm kev sib txuas ntau yam 8-ntsis CPU nrog rau hauv-system programmable Flash ntawm lub monolithic nti, Atmel AT89S52 yog lub microcontroller muaj zog uas muab cov kev daws teeb meem zoo heev thiab raug nqi rau ntau daim ntawv thov kev tswj hwm.AT89S52 muab cov qauv hauv qab no: 8K bytes ntawm Flash, 256 bytes ntawm RAM, 32 I / O kab, Watchdog timer, ob cov ntaub ntawv taw qhia, peb 16-ntsis timer / txee, rau-vector ob-theem cuam tshuam architecture, a tag nrho duplex serial chaw nres nkoj, on-chip oscillator, thiab moos circuitry.Tsis tas li ntawd, AT89S52 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 rau thaum qhov cuam tshuam tom ntej lossis kho vajtse pib dua.
