Kev piav qhia
Lub Atmel ATmega329/3290/649/6490 muab cov yam ntxwv hauv qab no: 32/64K bytes ntawm In-System Programmable Flash nrog Read-While-Sau peev xwm, 1/2K bytes EEPROM, 2/4K byte SRAM, 54/69 lub hom phiaj dav dav kuv / O kab, 32 lub hom phiaj ua haujlwm sau npe, JTAG interface rau Ciam-scan, On-chip Debugging kev txhawb nqa thiab kev ua haujlwm, ua tiav On-chip LCD maub los nrog kev tswj hwm sab hauv, peb lub sijhawm hloov pauv / Cov txee nrog kev sib piv, sab hauv thiab sab nraud cuam tshuam, ib qho programmable USART, Universal Serial Interface nrog Start Condition Detector, 8-channel, 10-ntsis ADC, programmable Watchdog Timer nrog cov Oscillator sab hauv, 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 Hwj Chim-down hom txuag cov ntaub ntawv sau npe tab sis khov Oscillator, cuam tshuam tag nrho lwm cov nti ua haujlwm kom txog thaum kev cuam tshuam tom ntej lossis kho vajtse pib dua.Nyob rau hauv lub hwj chim-txuag hom, lub asynchronous timer thiab lub LCD maub los tseem khiav, tso cai rau tus neeg siv tswj lub timer puag thiab khiav lub LCD zaub thaum lub sij hawm so ntawm lub cuab yeej tsaug zog.ADC Noise Reduction hom nres CPU thiab tag nrho I / O modules tshwj tsis yog asynchronous timer, LCD maub los 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.
