AT91SAM9CN12B-CFU

Based on the ARM926EJ-S processor, the SAM9CN12 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 SAM9CN12 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.
