Whakaahuatanga
Te Atmel® |Ko te raupapa SMART SAM3U he mema o te whanau o nga microcontrollers Flash i runga i te mahinga teitei 32-bit ARM® Cortex®-M3 RISC pūtukatuka.Ka mahi i te tere teitei o te 96 MHz me te whakaatu ki te 256 Kbytes o Flash me te 52 Kbytes o SRAM.Kei roto i te huinga peripheral tetahi Tauranga Pūrere USB Tere Tere me te transceiver kua whakauruhia, he MCI Tere Tere mo SDIO / SD / MMC, he Atanga Pahi waho me te kaiwhakahaere NAND Flash, ki te 4 USARTs, ki te 2 TWIs, ki te 5 SPIs, rite me te 4 PWM timers, kotahi 3-channel 16-bit moka-whānui matawā, he iti-mana RTC, he 12-bit ADC me te 10-bit ADC.Ko nga taputapu SAM3U e toru nga waahanga iti-hiko ka taea te whiriwhiri-rorohiko: Moe, Tatari, me te Purua.I roto i te aratau Moe, ka mutu te tukatuka i te wa e taea ai te mahi katoa o era atu mahi.I roto i te aratau Tatari, ka mutu nga karaka me nga mahi katoa engari ka taea te whirihora i etahi taputapu hei whakaoho i te punaha i runga i nga tikanga kua tautuhia.I roto i te aratau Pūrua, ko te RTC, RTT, me te arorau whakaoho anake e rere ana.Ko te Whakahaere Takahanga Wa-Tuturu ka taea e nga peripheral te whiwhi, te urupare me te tuku i nga huihuinga i roto i nga ahuatanga Hohe me te Moe me te kore e wawaohia e te tukatuka.Ko te hoahoanga SAM3U he mea hanga motuhake hei pupuri i nga whakawhitinga raraunga tere.Kei roto he matrix pahi maha-papa me te maha o nga peeke SRAM, PDC me DMA hongere e taea ai e ia te whakahaere i nga mahi i roto i te whakarara me te whakanui i te whakaputanga raraunga.Ka taea te mahi mai i te 1.62V ki te 3.6V ka tae mai ki roto i nga kohinga 100-pin me te 144-pin LQFP me BGA.Ko te taputapu SAM3U e tino pai ana mo nga tono USB: nga kaitautaunga raraunga, nga taputapu PC me tetahi piriti tere tere (USB ki SDIO, USB ki te SPI, USB ki te Atanga pahi o waho).
