Delivers Enhanced Connectivity

The Atmel® SAM3X ARM® Cortex™-M3 Flash-based microcontroller (MCU) brings more connectivity to the SAM3 family by adding Ethernet, dual CAN and high-speed USB (HS USB) MiniHost and device with on-chip physical layer (PHY). Devices feature a dual-bank configuration of 256KB and 512KB Flash total and are available in 100-pin and 144-pin QFP and BGA package options. The architecture is designed to support high-speed data transfers and includes a multi-layer bus matrix plus dual SRAM banks, direct memory access (DMA) channels and peripheral DMA controller (PDC) for applications supporting multi-task operations. The SAM3X series is ideal for networking applications in the industrial embedded market and in home and building automation, smart grids and industrial automation.

Key Features

  • Optimized for Connectivity — With its architecture and peripherals including Ethernet, dual CAN and HS USB MiniHost and device with on-chip PHY, the SAM3X is optimized for applications requiring high levels of connectivity.
  • Atmel QTouch Capacitive Touch Support — The SAM3X is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders and wheels functionality in your applications.
  • Enhanced Safety and Security — A variety of features integrated into the SAM3X series provide safety and security for your system. For example, dual-bank Flash enables safe in-system firmware upgrades. On-the-fly external memory scrambling on the 16-bit external bus interface enhances the protection of your external memory content, without impacting system performance. In addition, the SAM3X offers clock failure detection and a true random number generator.
  • Low Power Consumption — All SAM3 MCUs feature a sophisticated, flexible power management scheme that minimizes power consumption under all usage conditions. You can put the devices in back-up mode with the core and peripherals powered down, reducing power down to 2.5uA for the SAM3X series. A high-speed on-chip RC oscillator accelerates wake-up from back-up mode, further reducing average power consumption.
