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

Tsanangudzo

The Atmel® |SMART SAM3U yakatevedzana inhengo yemhuri yeFlash microcontrollers zvichibva pakuita kwepamusoro 32-bit ARM® Cortex®-M3 RISC processor.Inoshanda nekumhanya kukuru kwe96 MHz uye inosvika ku256 Kbytes yeFlash uye inosvika makumi mashanu neshanu Kbytes eSRAM.Iyo yeperipheral seti inosanganisira Yekumhanya USB Chishandiso Port ine yakadzikwa transceiver, High Speed ​​​​MCI yeSDIO/SD/MMC, Yekunze Bhazi Interface ine NAND Flash controller, anosvika mana USARTs, anosvika 2 TWIs, anosvika mashanu SPIs, se pamwe ne4 PWM timers, imwe 3-channel 16-bit general-chinangwa timer, yakaderera-simba RTC, 12-bit ADC uye gumi-bit ADC.Iyo SAM3U zvishandiso zvine matatu software-selectable yakaderera-simba modes: Kurara, Mirira, uye Backup.MuKurara mode, processor inomiswa apo mamwe mabasa ese anogona kuchengetwa achimhanya.MuKumirira modhi, wachi dzese uye mabasa zvinomiswa asi mamwe maperipheral anogona kugadzirwa kuti amutse sisitimu zvichienderana nemamiriro akatsanangurwa.Mune Backup mode, chete RTC, RTT, uye kumuka-kumuka logic ndiyo iri kushanda.Iyo Real-time Chiitiko Managment inobvumira peripherals kugamuchira, kuita uye kutumira zviitiko muActive uye Kurara modhi pasina kupindira kwe processor.Iyo SAM3U dhizaini yakanyatso kugadzirirwa kuchengetedza yakanyanya kumhanya data kutamiswa.Inosanganisira akawanda-layer bhazi matrix pamwe neakawanda SRAM mabhangi, PDC uye DMA chiteshi anoigonesa kuita mabasa pamwe chete uye kuwedzera data throughput.Inogona kushanda kubva 1.62V kusvika 3.6V uye inouya 100-pini uye 144-pini LQFP uye BGA mapakeji.Iyo SAM3U mudziyo unonyanya kukodzera maapplication eUSB: data logger, PC peripherals uye chero yakakwira bhiriji (USB kuSDIO, USB kuSPI, USB kune Kunze Bhazi Interface).
