AT89C2051-24PU IC MCU 8BIT 2KB FLASH 20DIP

Kev piav qhia

AT89C2051 yog qhov tsawg-voltage, ua haujlwm siab CMOS 8-ntsis microcomputer nrog 2K bytes ntawm Flash programmable thiab tshem tau nyeem nkaus xwb nco (PEROM).Cov cuab yeej yog tsim los ntawm Atmel's high-density nonvolatile memory technology thiab yog sib xws nrog kev lag luam-tus qauv MCS-51 cov lus qhia teeb.Los ntawm kev sib txuas ua ke ntau yam 8-ntsis CPU nrog Flash ntawm lub monolithic nti, Atmel AT89C2051 yog lub microcomputer muaj zog uas muab cov kev daws teeb meem zoo thiab raug nqi rau ntau daim ntawv thov kev tswj hwm.AT89C2051 muab cov qauv hauv qab no: 2K bytes ntawm Flash, 128 bytes ntawm RAM, 15 I / O kab, ob 16-ntsis timer / txee, tsib vector ob-theem cuam tshuam architecture, tag nrho duplex serial chaw nres nkoj, precision analog. Kev sib piv, on-chip oscillator thiab moos circuitry.Tsis tas li ntawd, AT89C2051 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 rau kev ua haujlwm txuas ntxiv.Lub hwj chim-down hom txuag cov ntsiab lus RAM tab sis khov lub oscillator disabling tag nrho lwm cov nti ua haujlwm kom txog rau thaum kho vajtse tom ntej.
