ATXMEGA256C3-AUR IC MCU 8 / 16BIT 256KB FLSH 64TQFP

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, ibikoresho bya AVR XMEGA bigera kuri CPU yinjira hafi ya miriyoni imwe kumasegonda (MIPS) kuri megahertz, bigatuma uwashizeho sisitemu yogukoresha 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 XMEGA C3 bitanga ibintu bikurikira: muri sisitemu ya flashable flash ifite ubushobozi bwo gusoma-mugihe cyo kwandika;imbere EEPROM na SRAM;sisitemu enye yibikorwa bya sisitemu na programable multilevel interrupt umugenzuzi, intego rusange 50 I / O imirongo, 16-bit-nyabyo-igihe (RTC);bitanu, 16-biti ya timer / kubara ugereranije numuyoboro wa PWM;USARTs eshatu;imirongo ibiri y'insinga ebyiri (TWIs);umuvuduko umwe wuzuye USB 2.0;ibice bibiri byuruhererekane (SPIs);umuyoboro umwe wa cumi na gatandatu, 12-bit ADC hamwe ninyungu zishobora gutegurwa;ibigereranyo bibiri 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 bya XMEGA C3 bifite software eshanu zishobora guhitamo uburyo bwo kuzigama ingufu.Uburyo budakora buhagarika CPU mugihe yemerera SRAM, ibyabaye sisitemu, guhagarika umugenzuzi, hamwe na peripheri zose gukomeza gukora.Uburyo bwo kumanura imbaraga bubika SRAM no kwandikisha ibirimo, ariko bigahagarika oscillator, bigahagarika indi mirimo yose kugeza igihe TWI itaha, USB izakomeza, cyangwa pin-ihinduka ikabuza, cyangwa igasubiramo.Muburyo bwo kuzigama imbaraga, asinchronous real-time counter ikomeza gukora, yemerera porogaramu kugumana igihe cyagenwe mugihe igikoresho gisigaye gisinziriye.Muburyo bwo guhagarara, oscillator yo hanze ikomeza gukora mugihe igikoresho gisigaye gisinziriye.Ibi bituma utangira byihuse kuva kristu yo hanze, ihujwe no gukoresha ingufu nke.Muburyo bwagutse bwo guhagarara, byombi oscillator nyamukuru hamwe nigihe ntarengwa gikomeza gukora.Kugirango ugabanye gukoresha ingufu, isaha ya peripheri kuri buri muntu ku giti cye irashobora guhagarikwa muburyo bukora nuburyo bwo gusinzira budafite akamaro.
