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

Kufotokozera

AT89C55WD ndi yamphamvu yotsika, yotsika kwambiri ya CMOS 8-bit microcontroller yokhala ndi ma byte 20K a Flash yomwe imatha kuwerenga kukumbukira ndi ma byte 256 a RAM.Chipangizochi chimapangidwa pogwiritsa ntchito ukadaulo waukadaulo wa Atmel's high-density nonvolatile memory ndipo umagwirizana ndi muyezo wamakampani 80C51 ndi 80C52 komanso pinout.The on-chip Flash imalola kukumbukira kwa pulogalamuyo kuti igwiritsidwe ntchito ndi pulogalamu yanthawi zonse yosasinthika.Pophatikiza 8-bit CPU yosunthika ndi Flash pa monolithic chip, Atmel AT89C55WD ndi kompyuta yaying'ono yamphamvu yomwe imapereka yankho losinthika komanso lotsika mtengo pamapulogalamu ambiri ophatikizidwa.AT89C55WD imapereka mawonekedwe awa: 20K mabayiti a Flash, 256 byte ya RAM, mizere 32 I/O, ma 16-bit timer/counters, ma vector asanu ndi limodzi, kapangidwe kawiri kosokoneza, doko lathunthu laduplex, pa-chip oscillator, ndi mawotchi ozungulira.Kuphatikiza apo, AT89C55WD idapangidwa ndi malingaliro osasunthika kuti igwire ntchito mpaka zero pafupipafupi ndipo imathandizira mitundu iwiri yosinthira mphamvu ya mapulogalamu.Idle Mode imayimitsa CPU kwinaku ikulola RAM, timer/counters, serial port, and interrupt system kuti ipitilize kugwira ntchito.Njira Yotsitsa Mphamvu imasunga zomwe zili mu RAM koma imawumitsa oscillator, kulepheretsa ntchito zina zonse za chip mpaka kusokoneza kwina kwina kapena kukonzanso kwa hardware.
