The AT91SAM9G46B-CU is a SMART Embedded Microprocessor Unit based on ARM926EJ-S processor, features the frequently requested combination of user interface functionality and high data rate connectivity, including LCD controller, resistive touchscreen, camera interface, audio, Ethernet 10/100 and high speed USB and SDIO. With the processor running at 400MHz and multiple 100+ Mbps data rate peripherals, the SAM9G46 provides adequate performance and bandwidth to the network or local storage media. The SAM9G46 eMPU supports DDR2 and NAND flash memory interfaces for program and data storage. An internal 133MHz multi-layer bus architecture associated with 39 DMA channels, a dual external bus interface and distributed memory including a 64kB SRAM that can be configured as a tightly coupled memory (TCM) sustains the high bandwidth required by the processor and the high speed peripherals.
