ATSAM3U2CA-AU IC MCU 32BIT 128KB IFLESHI 100LQFP

Inkcazo

I-Atmel® |Uchungechunge lwe-SMART SAM3U lilungu lentsapho ye-Flash microcontrollers ngokusekelwe ekusebenzeni okuphezulu kwe-32-bit ARM® Cortex®-M3 iprosesa ye-RISC.Isebenza ngesantya esiphezulu se-96 MHz kwaye ifaka ukuya kuthi ga kwi-256 Kbytes yeFlash kunye nokuya kuthi ga kwi-52 Kbytes ye-SRAM.Isethi ye-peripheral iquka i-Speed ​​​​Speed ​​​​Device Port Port ene-transceiver edibeneyo, i-Speed ​​​​Speed ​​​​MCI ye-SDIO / SD / MMC, i-External Bus Interface kunye nomlawuli we-NAND Flash, ukuya kwi-4 USARTs, ukuya kwi-2 TWIs, ukuya kwi-5 SPIs, njengoko kunye ne-4 PWM timers, enye i-3-channel 16 bit general-purpose timer, i-RTC yamandla aphantsi, i-12-bit ADC kunye ne-10-bit ADC.Izixhobo ze-SAM3U zineendlela ezintathu ezikhethiweyo zamandla aphantsi: Ukulala, Ukulinda, kunye ne-Backup.Kwimo yokulala, iprosesa iyamiswa ngelixa yonke eminye imisebenzi inokugcinwa isebenza.Kwimo yokulinda, zonke iiwotshi kunye nemisebenzi imisiwe kodwa ezinye iiperipherals zinokuqwalaselwa ukuvusa inkqubo ngokusekelwe kwiimeko ezichazwe kwangaphambili.Kwimowudi yogcino, kuphela i-RTC, i-RTT, kunye nengqiqo yokuvusa ezisebenzayo.Ulawulo Lweziganeko Lwexesha Lokwenyani luvumela iiperipherals ukuba zifumane, zisabele kwaye zithumele iminyhadala kwiindlela eziSebenzayo kunye nokuLala ngaphandle kongenelelo lomprosesa.Uyilo lwe-SAM3U lwenzelwe ngokukodwa ukugcina ukudluliselwa kwedatha yesantya esiphezulu.Ibandakanya i-matrix yebhasi ye-multi-layer kunye neebhanki ezininzi ze-SRAM, i-PDC kunye neziteshi ze-DMA ezivumela ukuba iqhube imisebenzi ngokuhambelanayo kunye nokwandisa umthamo wedatha.Iyakwazi ukusebenza ukusuka kwi-1.62V ukuya kwi-3.6V kwaye iza kwi-100-pin kunye ne-144-pin LQFP kunye neephakheji ze-BGA.Isixhobo se-SAM3U sifanelekile ngokukodwa kwizicelo ze-USB: abagcini bedatha, i-PC peripherals kunye nayiphi na ibhuloho yesantya esiphezulu (i-USB ukuya kwi-SDIO, i-USB kwi-SPI, i-USB kwi-External Bus Interface).
