Microchip AT91SAM9G45C-CU AT91SAM9G45C-CU ARM MCU Thumb SAM9 Family AT91SAM9G Series Microcontrollers ARM9 32 bit 400 MHz 64 KB

The AT91SAM9G45C-CU is a SMART 32-bit Embedded Microprocessor Unit based on ARM926EJ-S-based processor, features the frequently demanded 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 SAM9G45 provides adequate performance and bandwidth to the network or local storage media. The SAM9G45 eMPU supports DDR2 and NAND flash memory interfaces for program and data storage. An internal 133MHz multi-layer bus architecture associated with 37 DMA channels, a dual external bus interface and distributed memory including a 64kB SRAM which can be configured as a tightly coupled memory (TCM) sustains the high bandwidth required by the processor and the high speed peripherals. A true random number generator is embedded for key generation and exchange protocols.
