AT89C55WD-24PU IC MCU 8BIT 20KB FLASH 40DIP

Tsanangudzo

Iyo AT89C55WD ishoma-simba, yakakwirira-kuita CMOS 8-bit microcontroller ine 20K bytes yeFlash programmable inoverengeka ndangariro uye 256 bytes eRAM.Chishandiso ichi chinogadzirwa uchishandisa Atmel's high-density nonvolatile memory tekinoroji uye inoenderana neindasitiri chiyero 80C51 uye 80C52 yekuraira seti uye pinout.Iyo on-chip Flash inobvumira iyo ndangariro yepurogiramu kuti ive mushandisi yakarongwa neyakajairwa nonvolatile memory programmer.Nekubatanidza inogoneka 8-bit CPU neFlash pane monolithic chip, iyo Atmel AT89C55WD ine simba microcomputer iyo inopa inoshanduka uye inodhura mhinduro kune akawanda akadzikwa ekudzora maapplication.Iyo AT89C55WD inopa anotevera akajairwa maficha: 20K mabhayiti eFlash, 256 bytes eRAM, 32 I/O mitsara, matatu 16-bit timer/counter, matanhatu-vector, maviri-level kukanganisa architecture, yakazara-duplex serial port, on-chip oscillator, uye wachi yedunhu.Pamusoro pezvo, iyo AT89C55WD yakagadzirirwa ne static logic yekushanda pasi kusvika zero frequency uye inotsigira maviri software anosarudzwa ekuchengetedza simba modes.Iyo Idle Mode inomisa iyo CPU ichibvumira iyo RAM, timer/akaunda, serial port, uye kukanganisa system kuti ienderere mberi ichishanda.Iyo Power-down Mode inochengetedza zviri mukati me RAM asi inoomesa oscillator, ichivharira mamwe ese chip mabasa kusvika iyo inotevera yekunze kukanganisa kana hardware reset.
