AT90CAN128-16AU IC MCU 8BIT 128KB FLASH 64TQFP

Sharaxaada

AT90CAN32/64/128 waa awood yar oo CMOS 8-bit microcontroller ah oo ku salaysan AVR-ga la xoojiyey ee dhismaha RISC.Iyadoo lagu fulinayo tilmaamo awood leh hal wareeg oo hal saac ah, AT90CAN32/64/128 waxay ku guulaysataa waxsoosaarka soo dhawaynta 1 MIPS halkii MHz taasoo u oggolaanaysa naqshadeeyaha nidaamka inuu wanaajiyo isticmaalka tamarta iyo xawaaraha socodsiinta.Xudunta AVR waxay isku daraysaa hab waxbarasho oo qani ah iyo 32 ujeedo shaqo oo guud.Dhammaan 32 ka diiwaan waxay si toos ah ugu xidhan yihiin Unugga Macquulka Xisaabta (ALU), taas oo u oggolaanaysa laba diiwaan oo madaxbannaan in la galo hal tilmaam oo lagu fuliyo hal wareeg oo saacad ah.Naqshadeynta natiijadeedu waa ka hufan tahay kood marka la gaaro wax soo saarka ilaa toban jeer ka dhaqso badan kantaroolayaasha CISC ee caadiga ah.AT90CAN32/64/128 waxay bixisaa sifooyinka soo socda: 32K/64K/128K bytes ee In-System Programmable Flash oo leh awood wax-akhris, 1K/2K/4K bytes EEPROM, 2K/4K/4K bytes SRAM, 53 ujeedo guud Khadadka I/O, 32 diiwangelin shaqo oo ujeedo guud ah, kontaroolaha CAN, Counter Time-ka dhabta ah (RTC), afar saacad/ xisaabiye dabacsan oo leh hababka isbarbardhigga iyo PWM, 2 USARTs, Interface Serial Laba-fire ah oo bayyt ku jihaysan, 8-channel 10 -bit ADC oo leh marxalad kala duwanaansho ikhtiyaari ikhtiyaari ah oo leh faa'iido barnaamij, saacad saacadle ah oo Watchdog ah oo leh Oscillator gudaha ah, deked taxane ah oo SPI ah, IEEE std.1149.1 waafaqsan interface tijaabada JTAG, sidoo kale loo isticmaalo gelitaanka nidaamka Debug on-chip iyo barnaamijka iyo shan software oo la dooran karo hababka badbaadinta awoodda.Habka Idle-ku wuxuu joojiyaa CPU-ga isagoo u oggolaanaya SRAM, Timer/Counters, SPI/CAN dekedaha iyo nidaamka kala goynta inay sii shaqeeyaan.Habka Power-down-ku wuxuu badbaadiyaa waxyaabaha ku jira diiwaanka laakiin wuxuu qaboojiyaa Oscillator-ka, wuxuu curyaamiyaa dhammaan hawlaha kale ee chip ilaa inta soo socota kala go'a ama Dib-u-dejinta Hardware.Qaabka Keydka Awooda, saacada asynchronous-ku wuu sii socdaa, taas oo u ogolaanaysa isticmaaluhu in uu ilaashado saldhiga saacada inta qalabka intiisa kale hurdo.Habka dhimista buuqa ee ADC wuxuu joojiyaa CPU iyo dhammaan qaybaha I/O marka laga reebo saacadda Asynchronous iyo ADC, si loo yareeyo dhawaaqa beddelka inta lagu jiro beddelka ADC.Qaabka heeganka ah, Crystal/Resonator Oscillator ayaa shaqaynaya inta qalabka intiisa kale uu hurdo.Tani waxay u ogolaanaysaa bilawga degdega ah oo ay weheliso isticmaalka tamarta yar.Qalabka waxaa lagu soo saaray iyadoo la adeegsanayo tignoolajiyada xusuusta ee cufnaanta sare ee Atmel.Onchip ISP Flash wuxuu u ogolaanayaa xusuusta barnaamijka in dib loogu habeeyo nidaamka dhexdiisa iyadoo loo marayo istiraatijiyad taxane ah oo SPI ah, barnaamijka xusuusta aan isbeddelayn ee caadiga ah, ama barnaamijka On-chip Boot ee ku shaqeeya xudunta AVR.Barnaamijka boot wuxuu isticmaali karaa interface kasta si uu u soo dejiyo barnaamijka codsiga ee xusuusta Flash.Software-ka ku jira qaybta Boot Flash wuxuu sii wadi doonaa inuu shaqeeyo inta qaybta Flash Application la cusboonaysiinayo, taasoo bixinaysa wax-akhris-intii-qoraal dhab ah.
