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

Kufotokozera

The Atmel® |SMART SAM3U mndandanda ndi membala wa banja la Flash microcontrollers kutengera magwiridwe antchito apamwamba a 32-bit ARM® Cortex®-M3 RISC purosesa.Imagwira pa liwiro lalikulu la 96 MHz ndipo imakhala ndi 256 Kbytes ya Flash ndi mpaka 52 Kbytes ya SRAM.Seti yozungulira imaphatikizapo Doko la High Speed ​​​​USB Device Port yokhala ndi transceiver yophatikizidwa, High Speed ​​​​MCI ya SDIO/SD/MMC, Chiyankhulo cha Mabasi Akunja okhala ndi NAND Flash controller, mpaka 4 USARTs, mpaka 2 TWIs, mpaka 5 SPIs, monga komanso 4 PWM timer, 3-channel 16-bit general-purpose timer, RTC yamphamvu yochepa, 12-bit ADC ndi 10-bit ADC.Zipangizo za SAM3U zili ndi mitundu itatu yamagetsi yosankhidwa ndi mapulogalamu: Kugona, Dikirani, ndi Kusunga.Munjira yogona, purosesa imayimitsidwa pomwe ntchito zina zonse zitha kusungidwa.Mu Wait mode, mawotchi onse ndi ntchito zimayimitsidwa koma zotumphukira zina zitha kukonzedwa kuti zidzutse dongosolo potengera zomwe zafotokozedweratu.Muzosunga zobwezeretsera, ndi RTC, RTT, ndi malingaliro odzutsa okha omwe akuyenda.The Real-time Event Managment imalola zotumphukira kulandira, kuchitapo kanthu ndi kutumiza zochitika mumayendedwe a Active ndi Tulo popanda purosesa.Zomangamanga za SAM3U zidapangidwa makamaka kuti zithandizire kusamutsa kwa data mwachangu.Zimaphatikizapo matrix a mabasi ambiri komanso mabanki angapo a SRAM, PDC ndi DMA njira zomwe zimawathandiza kuti azigwira ntchito mofanana ndi kupititsa patsogolo deta.Ikhoza kugwira ntchito kuchokera ku 1.62V kufika ku 3.6V ndipo imabwera mu 100-pini ndi 144-pini LQFP ndi BGA phukusi.Chipangizo cha SAM3U ndichoyenera kwambiri ku mapulogalamu a USB: odula ma data, zotumphukira za PC ndi mlatho uliwonse wothamanga kwambiri (USB kupita ku SDIO, USB kupita ku SPI, USB kupita Kunja kwa Bus Interface).
