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

Kufotokozera

AT89C2051 ndi kakompyuta kakang'ono kakang'ono ka CMOS 8-bit kakang'ono kakang'ono kamene kamakhala ndi ma 2K bytes a Flash programmable komanso yofufutika yowerengera-yokha kukumbukira (PEROM).Chipangizochi chimapangidwa pogwiritsa ntchito ukadaulo wa Atmel's high-density nonvolatile memory ndipo umagwirizana ndi malangizo amakampani a MCS-51.Mwa kuphatikiza 8-bit CPU yosunthika ndi Flash pa chip monolithic, Atmel AT89C2051 ndi makina apakompyuta amphamvu omwe amapereka njira yosinthika komanso yotsika mtengo pamapulogalamu ambiri ophatikizidwa.AT89C2051 imapereka mawonekedwe awa: 2K mabayiti a Flash, 128 byte ya RAM, mizere 15 ya I/O, ma 16-bit timer/counters, ma vector asanu amitundu iwiri yosokoneza, doko lathunthu la serial, analogi yolondola. comparator, on-chip oscillator ndi mawotchi ozungulira.Kuphatikiza apo, AT89C2051 idapangidwa ndi malingaliro osasunthika kuti igwire ntchito mpaka ziro pafupipafupi ndipo imathandizira mitundu iwiri yosankha yopulumutsira mphamvu yamapulogalamu.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 kuyambiranso kwa hardware.
