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

Inkcazo

I-AT89C55WD inamandla aphantsi, i-high-performance CMOS 8-bit microcontroller ene-20K bytes ye-Flash programmable efundwayo kuphela imemori kunye ne-256 bytes ye-RAM.Isixhobo senziwa kusetyenziswa itekhnoloji yememori engaguquguqukiyo ephezulu ye-Atmel kwaye iyahambelana nomgangatho woshishino we-80C51 kunye ne-80C52 yomyalelo kunye ne-pinout.I-Flash ekwi-chip ivumela imemori yenkqubo ukuba ibe ngumsebenzisi ecwangciswe ngumdwelisi wememori oqhelekileyo ongaguqukiyo.Ngokudibanisa i-CPU ye-8-bit ene-Flash kwi-chip ye-monolithic, i-Atmel AT89C55WD yi-microcomputer enamandla enika isisombululo esiguquguqukayo kunye nexabiso elisebenzayo kwiinkqubo ezininzi zokulawula ezifakwe ngaphakathi.I-AT89C55WD ibonelela ngezi mpawu zisemgangathweni zilandelayo: I-20K bytes yeFlash, i-256 bytes ye-RAM, imigca ye-32 ye-I / O, ezintathu ze-16-bit timer / counters, i-vector emithandathu, i-architecture yokuphazamiseka kwamanqanaba amabini, i-port-duplex ye-serial port, kwi-chip oscillator, kunye nokujikeleza iwotshi.Ukongeza, i-AT89C55WD iyilwe nge-static logic yokusebenza ukuya kuthi ga kwi-zero frequency kwaye ixhasa iindlela ezimbini ezikhethiweyo zokugcina amandla.I-Idle Mode imisa i-CPU ngelixa ivumela i-RAM, i-timer / counters, i-serial port, kunye nenkqubo yokuphazamisa ukuqhubeka nokusebenza.I-Power-down Mode igcina imixholo ye-RAM kodwa ifake i-oscillator, ikhubaze yonke eminye imisebenzi ye-chip kude kube kuphazamiseke kwangaphandle okulandelayo okanye ukusetwa kwakhona kwe-hardware.
