I-ATSAM3U2CA-AU IC MCU 32BIT 128KB IFLASH 100LQFP

Incazelo

I-Atmel® |Uchungechunge lwe-SMART SAM3U luyilungu lomndeni lama-Flash microcontrollers asekelwe ekusebenzeni okuphezulu kwe-32-bit ARM® Cortex®-M3 RISC processor.Isebenza ngesivinini esiphezulu esingu-96 MHz futhi ifaka kufika ku-256 Kbytes we-Flash nokufika ku-52 Kbytes we-SRAM.Isethi ye-peripheral ihlanganisa Imbobo Yedivayisi ye-USB enesivinini esikhulu esine-transceiver eshumekiwe, i-High Speed ​​​​MCI ye-SDIO/SD/MMC, Isixhumi esibonakalayo Sebhasi Yangaphandle nesilawuli se-NAND Flash, kufika ku-4 USARTs, kufika ku-2 TWIs, kufika kuma-SPI angu-5, njengoba kanye nezibali-sikhathi ze-PWM ezi-4, isibali sikhathi esisodwa se-3-channel 16-bit general-purpose, i-RTC enamandla aphansi, i-12-bit ADC kanye ne-10-bit ADC.Amadivayisi e-SAM3U anezindlela ezintathu zamandla aphansi ezikhethwa yisoftware: Ukulala, Ukulinda, kanye Nesipele.Kumodi yokulala, iphrosesa iyamiswa kuyilapho yonke eminye imisebenzi ingagcinwa isebenza.Kumodi yokulinda, wonke amawashi nemisebenzi iyamiswa kodwa amanye ama-peripherals angalungiselelwa ukuvusa isistimu ngokusekelwe kuzimo ezichazwe ngaphambilini.Kumodi Yokwenza Ikhophi Yasenqolobaneni, i-RTC, i-RTT, ne-wake-up logic kuphela esebenzayo.Ukuphathwa Komcimbi Wesikhathi Sangempela kuvumela ama-peripherals ukuthi amukele, asabele futhi athumele imicimbi ngamamodi Asebenzayo kanye Nezokulala ngaphandle kokungenela komcubunguli.Isakhiwo se-SAM3U senzelwe ngqo ukusimamisa ukudluliswa kwedatha ngesivinini esikhulu.Ihlanganisa i-matrix yebhasi enezingqimba eziningi kanye namabhange amaningi e-SRAM, i-PDC neziteshi ze-DMA ezivumela ukuthi iqhube imisebenzi ngokuhambisana futhi ikhulise ukuphuma kwedatha.Ingasebenza ukusuka ku-1.62V iye ku-3.6V futhi iza ngamaphakeji angu-100 namaphini angu-144 LQFP kanye ne-BGA.Idivayisi ye-SAM3U ifaneleka kakhulu izinhlelo zokusebenza ze-USB: abagawuli bedatha, amapheripheral e-PC nanoma yiliphi ibhuloho elinesivinini esikhulu (i-USB ukuya ku-SDIO, i-USB kuya ku-SPI, i-USB kuya ku-External Bus Interface).
