AT89C4051-24PU IC MCU 8BIT 4KB FLASH 20DIP

Kev piav qhia

AT89C4051 yog qhov qis-voltage, ua haujlwm siab CMOS 8-ntsis microcontroller nrog 4K bytes ntawm Flash programmable thiab tshem tau nyeem nkaus xwb nco.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 AT89C4051 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.AT89C4051 muab cov qauv hauv qab no: 4K 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, a precision analog piv, on-chip oscillator thiab moos circuitry.Tsis tas li ntawd, AT89C4051 yog tsim los nrog cov logic zoo li qub rau kev ua haujlwm mus rau xoom zaus thiab txhawb nqa ob hom software-xaiv lub zog txuag.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.
