This article is forwarded from Atmel, it mainly describes the delighted features of the new Atmel AT91SAM9G45 ARM9 Microcontroller which is released by Atmel in December of 2009.
Atmel's SAM9G45 is a high-performance eMPU with the right peripheral mix and performance characteristics to make it the ideal solution for main powered, cost-sensitive industrial applications such as industrial & building control, HVAC, POS terminals, alarm systems, printers and medical.
High-speed Connectivity and Intelligent User Interfaces
Combines 100 Mbps+ data rates on multiple high-speed peripherals including HS USB, Ethernet 10/100, SDIO/SDCard, MMC with advanced intelligent User Interfaces (LCD, Camera, Touch screen and audio interfaces).
High Performance Data Speedway
Features a processor clock running at 400 MHz and a high data-bandwidth architecture based on a 12-layer bus matrix with 37 DMA channels. Dual External Bus Interface supporting distributed on- and off-chip memory.
Next-generation Memories
Offers DDR2 and NAND Flash support, in addition to SDRAM and NOR Flash, with boot from NAND Flash, SDCard, DataFlash
or serial DataFlash.
Low Power, Low Cost
Only 350µW/MHz at 400 MHz operation and 8µA backup mode. 3.3V IOs eliminate the need for external level shifters.
