ATSAM3X8E-AU

Description The Atmel  | SMART SAM3X/A series is a member of a family of Flash microcontrollers based on the high performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 84 MHz and features up to 512 Kbytes of Flash and up to 100 Kbytes of SRAM. The peripheral set includes a High Speed USB Host and Device port with embedded transceiver, an Ethernet MAC, 2 CANs, a High Speed MCI for SDIO/SD/MMC, an External Bus Interface with NAND Flash Controller (NFC), 5 UARTs, 2 TWIs, 4 SPIs, as well as a PWM timer, three 3-channel general-purpose 32-bit timers, a low-power RTC, a lowpower RTT, 256-bit General Purpose Backup Registers, a 12-bit ADC and a 12-bit DAC. The SAM3X/A devices have three software-selectable low-power modes: Sleep, Wait and Backup. In Sleep mode, the processor is stopped while all other functions can be kept running. In Wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on predefined conditions. In Backup mode, only the RTC, RTT, and wake-up logic are running. The SAM3X/A series is ready for capacitive touch thanks to the QTouch library, offering an easy way to implement buttons, wheels and sliders. The SAM3X/A architecture is specifically designed to sustain high-speed data transfers. It includes a multi-layer bus matrix as well as multiple SRAM banks, PDC and DMA channels that enable it to run tasks in parallel and maximize data throughput. The device operates from 1.62V to 3.6V and is available in 100 and 144-lead LQFP, 100-ball TFBGA and 144-ball LFBGA packages. The SAM3X/A devices are particularly well suited for networking applications: industrial and home/building automation, gateways.
