ATSAM3X8EA-AU IC MCU 32BIT 512KB FLASH 144LQFP

Kufotokozera

Atmel |SMART SAM3X/A 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 84 MHz ndipo imakhala ndi 512 Kbytes ya Flash ndi mpaka 100 Kbytes ya SRAM.Seti yozungulira imaphatikizapo High Speed ​​​​USB Host ndi doko la Chipangizo chokhala ndi transceiver yophatikizidwa, Ethernet MAC, 2 CANs, High Speed ​​​​MCI ya SDIO/SD/MMC, Chiyankhulo Chakunja cha Bus chokhala ndi NAND Flash Controller (NFC), 5 UARTs, 2 TWIs, 4 SPIs, komanso PWM timer, 3-channel general-purpose 32-bit timer, RTC yamphamvu yochepa, RTT yotsika kwambiri, 256-bit General Purpose Backup Registers, 12-bit ADC ndi 12 - pang'ono DAC.Zipangizo za SAM3X/A zili ndi mitundu itatu yamphamvu yosankha mapulogalamu: Kugona, Kudikirira ndi Kusunga Zosunga.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.Mndandanda wa SAM3X/A ndiwokonzeka kukhudza capacitive chifukwa cha laibulale ya QTouch, yopereka njira yosavuta yokhazikitsira mabatani, mawilo ndi masilidi.Zomangamanga za SAM3X/A 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.Chipangizocho chimagwira ntchito kuchokera ku 1.62V mpaka 3.6V ndipo chimapezeka mu 100 ndi 144-lead LQFP, 100-mpira TFBGA ndi 144-mpira LFBGA phukusi.Zipangizo za SAM3X/A ndizoyenera kwambiri kugwiritsa ntchito maukonde: mafakitale ndi nyumba / zomanga nyumba, zipata.
