ATXMEGA128B1-AU IC MCU 8/16B 128KB FLASH 100TQFP

Kev piav qhia

Cov khoom siv Atmel AVR XMEGA B1 muab cov yam ntxwv hauv qab no: hauv-system programmable flash nrog kev nyeem ntawv-thaum-sau muaj peev xwm;Internal EEPROM thiab SRAM;ob-channel DMA maub los, plaub-channel kev tshwm sim system thiab programmable multilevel interrupt controller, 53 lub hom phiaj dav dav I / O kab, lub sijhawm tiag tiag (RTC);Liquid Crystal Display txhawb nqa mus txog 4x40 ntu tsav tsheb, ASCII cim daim duab qhia thiab kev tswj hwm qhov sib txawv (LCD);peb hloov tau, 16-ntsis timer/counters nrog sib piv thiab PWM raws;ob USARTs;ib tug ob-xaim serial interface (TWI);ib qho puv ceev USB 2.0 interface;ib qho serial peripheral interface (SPI);AES thiab DES cryptographic cav;ob 8-channel, 12-ntsis ADCs nrog programmable nce;plaub analog piv (ACs) nrog lub qhov rais hom;programmable watchdog timer nrog cais sab hauv oscillator;muaj tseeb oscillators nrog PLL thiab prescaler;thiab programmable brown-out detection.Qhov kev pab cuam thiab debug interface (PDI), ceev, ob-pin interface rau programming thiab debugging, muaj.Cov khoom siv kuj muaj IEEE std.1149.1 raws li JTAG interface, thiab qhov no kuj tseem siv tau rau ntawm-chip debug thiab programming.Cov khoom siv ATx ​​muaj tsib software xaiv lub zog txuag hom.Hom tsis ua haujlwm nres lub CPU thaum tso cai rau SRAM, DMA maub los, qhov xwm txheej txheej txheem, cuam tshuam tus tswj, thiab tag nrho cov khoom siv txuas ntxiv ua haujlwm.Lub hwj chim-down hom txuag lub SRAM thiab sau npe cov ntsiab lus, tab sis nres cov oscillators, disabling tag nrho lwm yam functions kom txog rau thaum lub tom ntej no TWI, USB resume, los yog pin-hloov cuam tshuam, los yog rov pib dua.Hauv hom kev txuag hluav taws xob, lub asynchronous real-time counter txuas ntxiv khiav, tso cai rau daim ntawv thov tswj lub sijhawm timer thaum lub sijhawm so ntawm lub cuab yeej tsaug zog.Hauv hom txuag hluav taws xob, lub LCD maub los tau tso cai los kho cov ntaub ntawv rau lub vaj huam sib luag.Nyob rau hauv hom standby, sab nraud siv lead ua oscillator tseem khiav thaum tus so ntawm lub cuab yeej tsaug zog.Qhov no tso cai rau kev pib sai heev los ntawm sab nraud siv lead ua, ua ke nrog kev siv hluav taws xob tsawg.Nyob rau hauv hom standby txuas ntxiv, ob qho tib si lub ntsiab oscillator thiab lub sijhawm asynchronous txuas ntxiv mus, thiab lub LCD tswj tau tso cai los hloov cov ntaub ntawv rau lub vaj huam sib luag.Txhawm rau txo qis kev siv hluav taws xob ntxiv, lub moos peripheral rau txhua tus neeg peripheral tuaj yeem xaiv tau nres hauv hom nquag thiab tsis siv neeg pw tsaug zog.Atmel muaj QTouch® tsev qiv ntawv pub dawb rau embedding capacitive touch nyees khawm, sliders thiab log ua haujlwm rau hauv AVR microcontrollers.
