ATXMEGA256A3U-MH IC MCU 8/16BIT 256KB FLASH 64QFN

Kev piav qhia

Lub Atmel AVR XMEGA yog tsev neeg uas tsis muaj zog, kev ua haujlwm siab, thiab cov khoom siv peripheral nplua nuj 8/16-ntsis microcontrollers raws li AVR txhim kho RISC architecture.Los ntawm kev ua raws li cov lus qhia hauv ib lub voj voog ib zaug, AVR XMEGA ntaus ntawv ua tiav los ntawm CPU mus txog ib lab cov lus qhia ib thib ob (MIPS) ib megahertz, tso cai rau tus tsim qauv tsim kho lub zog noj piv rau kev ua haujlwm ceev.AVR CPU sib txuas cov kev qhia nplua nuj nrog 32 lub hom phiaj ua haujlwm rau npe.Tag nrho 32 cov ntawv sau npe tau txuas ncaj qha mus rau chav ntsuas lej lej (ALU), tso cai rau ob daim ntawv sau npe ywj pheej nkag rau hauv ib qho kev qhia, ua tiav hauv ib lub voj voog.Cov txiaj ntsig tau txais txiaj ntsig yog cov lej zoo dua thaum ua tiav cov txiaj ntsig ntau zaus sai dua li cov pa ib leeg-accumulator lossis CISC raws li microcontrollers.AVR XMEGA A3U pab kiag li lawm muab cov yam ntxwv hauv qab no: hauv-system programmable flash nrog cov peev xwm nyeem-whilewrite;Internal EEPROM thiab SRAM;plaub-channel DMA maub los, yim-channel kev tshwm sim system thiab programmable multilevel cuam tshuam xws li, 50 lub hom phiaj I / O kab, 16-ntsis real-time txee (RTC);xya hloov tau, 16-ntsis timer/counters nrog sib piv thiab PWM raws;xya USARTs;ob-xaim serial interfaces (TWIs);ib qho puv ceev USB 2.0 interface;peb serial peripheral interfaces (SPIs);AES thiab DES cryptographic cav;ob 16-channel, 12-ntsis ADCs nrog programmable nce;ib 2-channel 12-ntsis DAC;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 ciam teb scan, on-chip debug thiab programming.
