Kev piav qhia
Lub Atmel® 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.ATmega8 muab cov yam ntxwv hauv qab no: 8 Kbytes ntawm In-System Programmable Flash nrog Kev Nyeem-Thaum-Sau muaj peev xwm, 512 bytes ntawm EEPROM, 1 Kbyte ntawm SRAM, 23 lub hom phiaj dav dav I / O kab, 32 lub hom phiaj ua haujlwm sau npe, peb lub sijhawm hloov pauv. / Cov txee nrog cov qauv sib piv, kev cuam tshuam sab hauv thiab sab nraud, ib qho programmable USART, ib byte taw qhia Twowire Serial Interface, 6-channel ADC (yim raws hauv TQFP thiab QFN / MLF pob) nrog 10-ntsis raug, programmable Watchdog Timer nrog Internal Oscillator, SPI serial chaw nres nkoj, thiab tsib software xaiv lub zog txuag hom.Hom Idle nres lub CPU thaum tso cai rau SRAM, Timer / Counters, SPI chaw nres nkoj, thiab cuam tshuam rau kev ua haujlwm txuas ntxiv.Lub Powerdown hom txuag cov ntaub ntawv sau npe tab sis khov Oscillator, cuam tshuam tag nrho lwm cov nti ua haujlwm kom txog rau thaum tom ntej cuam tshuam lossis kho vajtse pib dua.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 lub CPU thiab tag nrho I / O modules tshwj tsis yog asynchronous timer thiab ADC, kom txo cov suab nrov thaum hloov pauv ADC.Nyob rau hauv Standby hom, lub siv lead ua / resonator Oscillator tab tom khiav thaum tus 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.
