ATXMEGA256A3U-MH IC MCU 8 / 16BIT 256KB FLASH 64QFN

Ibisobanuro

Atmel AVR XMEGA ni umuryango wububasha buke, bukora neza, hamwe na peripheri ikungahaye kuri microcontrollers ishingiye kuri AVR yongerewe ubwubatsi bwa RISC.Mugukurikiza amabwiriza mugihe cyisaha imwe, igikoresho cya AVR XMEGA kigera kumasoko CPU yegera amabwiriza ya miriyoni kumasegonda (MIPS) kuri megahertz, bigatuma umushinga wa sisitemu ashobora gukoresha ingufu hamwe numuvuduko wo gutunganya.AVR CPU ikomatanya amabwiriza akungahaye hamwe na 32 rusange yibikorwa byakazi.Ibitabo byose uko ari 32 byahujwe neza na arithmetic logic unit (ALU), bituma ibitabo bibiri byigenga bigerwaho mumabwiriza amwe, bikorerwa mumasaha imwe.Ubwubatsi bwavuyemo ni kode ikora neza mugihe igera kubisubizo inshuro nyinshi byihuse kuruta ibisanzwe-byegeranya cyangwa CISC ishingiye kuri microcontrollers.Ibikoresho bya AVR XMEGA A3U bitanga ibintu bikurikira: muri sisitemu ya porogaramu ishobora gukoreshwa hamwe nubushobozi bwo gusoma-kwandika;imbere EEPROM na SRAM;imiyoboro ine ya DMA umugenzuzi, sisitemu y'ibyiciro umunani sisitemu hamwe na programable multilevel interrupt umugenzuzi, intego 50 rusange I / O imirongo, 16-bit-nyabyo-igihe (RTC);birindwi byoroshye, 16-biti ya timer / kubara ugereranije numuyoboro wa PWM;birindwi USART;imirongo ibiri y'insinga ebyiri (TWIs);umuvuduko umwe wuzuye USB 2.0;ibice bitatu byuruhererekane (SPIs);AES na DES moteri yerekana amashusho;bibiri-16-imiyoboro, 12-bit ADC hamwe ninyungu zishobora gutegurwa;umuyoboro umwe-umuyoboro wa 12-bit DAC;ibigereranyo bine bigereranya (AC) hamwe nuburyo bwidirishya;porogaramu ishobora gukurikiranwa igihe hamwe na oscillator y'imbere;oscillator yukuri imbere hamwe na PLL na prescaler;na programable brown-out detection.Porogaramu na debug interface (PDI), yihuta, ibice bibiri-pin yo gutangiza gahunda no gukemura, irahari.Ibikoresho kandi bifite std ya IEEE.1149.1 yujuje interineti ya JTAG, kandi ibi birashobora no gukoreshwa mugusuzuma imbibi, kuri chip debug na programming.
