　　Based on the ARM926EJ-S™ processor， the Atmel® SAM9N12/CN11/CN12 devices offer the frequently-requested combination of user interface functionality and high data rate connectivity， with LCD Controller， resistive touch-screen， multiple UARTs， SPI， I2C， full-speed USB Host and Device and SDIO. The SAM9N12/CN11/CN12 support the latest generation of LPDDR/DDR2 and NAND Flash memory interfaces for program and data storage. An internal 133 MHz multilayer bus architecture associated with eight DMA channels and distributed memory – including a 32-Kbyte SRAM – sustains the high bandwidth required by the processor and the high-speed peripherals. The SAM9CN12/CN11 offers on-chip hardware accelerators with DMA support that enable high-speed data encryption and authentication of transferred data or applications. Supported standards are up to 256-bit AES， and FIPS Publication 180-2 compliant SHA1 and SHA256. A True Random Number Generator is embedded for key generation and exchange protocols. The devices also feature fuse bits for crypto key （SAM9CN12）， user configuration （SAM9N12 and SAM9CN11） and device configuration （all）。 The SAM9CN12 includes a secured Boot ROM; the SAM9N12 and SAM9CN11 include a standard Boot ROM. The I/Os support 1.8V or 3.3V operation and are independently configurable for the memory interface and peripheral I/Os. This feature eliminates the need for any external level shifters， while 0.8 ball pitch packages lower PCB cost and complexity. The SAM9N12/CN11/CN12 power management controllers feature efficient clock gating and a battery backup section that minimizes power consumption in active and standby modes. There are several devices. The table that follows presents the embedded features of each device.
