Kev piav qhia
AT90CAN32/64/128 yog lub zog qis CMOS 8-ntsis microcontroller raws li AVR txhim kho RISC architecture.Los ntawm kev ua tiav cov lus qhia muaj zog hauv ib lub voj voog ib zaug, AT90CAN32 / 64 / 128 ua tiav cov txiaj ntsig nce mus txog 1 MIPS ib MHz tso cai rau tus tsim qauv tsim kom zoo zog siv hluav taws xob piv rau kev ua haujlwm ceev.AVR core muab cov txheej txheem kev qhia nplua nuj nrog 32 lub hom phiaj ua haujlwm.Tag nrho 32 cov ntawv sau npe tau txuas ncaj qha mus rau Arithmetic Logic Unit (ALU), tso cai rau ob daim ntawv sau npe nkag mus rau hauv ib qho kev qhia ua tiav hauv ib lub voj voog.Cov txiaj ntsig tau txais txiaj ntsig zoo dua li cov lej zoo thaum ua tiav cov txiaj ntsig txog li kaum zaus sai dua li cov qauv CISC microcontrollers.Lub AT90CAN32/64/128 muab cov yam ntxwv hauv qab no: 32K / 64K / 128K bytes ntawm In-System Programmable Flash nrog Read-While-Sau peev xwm, 1K / 2K / 4K bytes EEPROM, 2K / 4K / 4K bytes SRAM, 53 lub hom phiaj dav dav I/O kab, 32 lub hom phiaj ua haujlwm sau npe, CAN maub los, Lub Sijhawm Lub Sijhawm (RTC), plaub lub sijhawm hloov pauv / Counters nrog cov qauv sib piv thiab PWM, 2 USARTs, ib byte taw qhia Ob-xaim Serial Interface, 8-channel 10 -ntsis ADC nrog kev xaiv qhov sib txawv ntawm cov tswv yim sib txawv nrog qhov programmable nce, programmable Watchdog Timer nrog Internal Oscillator, SPI serial chaw nres nkoj, IEEE std.1149.1 raws li JTAG xeem interface, kuj siv rau kev nkag mus rau On-chip Debug system thiab programming thiab tsib software xaiv lub zog txuag hom.Hom Idle nres lub CPU thaum tso cai rau SRAM, Timer / Counters, SPI / CAN cov chaw nres nkoj thiab cuam tshuam rau kev ua haujlwm txuas ntxiv.Lub Hwj Chim-down hom txuag cov ntawv sau npe tab sis khov Oscillator, cuam tshuam tag nrho lwm cov nti ua haujlwm kom txog rau thaum qhov cuam tshuam tom ntej lossis Hardware Reset.Nyob rau hauv lub hwj chim-txuag hom, lub asynchronous timer tseem khiav, tso cai rau tus neeg siv tswj lub timer puag thaum tus so ntawm lub cuab yeej tsaug zog.ADC Noise Reduction hom nres CPU thiab tag nrho I / O modules tshwj tsis yog Asynchronous Timer thiab ADC, kom txo cov suab nrov thaum hloov pauv ADC.Hauv hom Standby, Crystal / Resonator Oscillator tab tom khiav thaum lub sijhawm so ntawm lub cuab yeej tsaug zog.Qhov no tso cai rau kev pib sai heev ua ke nrog kev siv hluav taws xob tsawg.Cov cuab yeej yog tsim los siv Atmel's high-density nonvolatile memory technology.Lub Onchip ISP Flash tso cai rau qhov kev pab cuam nco tau reprogrammed nyob rau hauv-system los ntawm ib tug SPI serial interface, los ntawm cov pa ib tug tsis muaj zog nco programmer, los yog los ntawm ib tug On-chip Boot program khiav ntawm lub AVR core.Qhov kev pab cuam khau raj tuaj yeem siv txhua qhov sib cuam tshuam los rub tawm cov ntawv thov kev pab cuam hauv daim ntawv thov Flash nco.Software hauv Boot Flash seem yuav khiav mus ntxiv thaum Daim Ntawv Thov Flash ntu tau hloov kho, muab qhov tseeb nyeem-Thaum-Sau ua haujlwm.
