方案关键器件表：

　　The AT91RM9200-QU-002 is a complete system-on-chip 32-bit Microcontroller built around the ARM920T ARM Thumb RISC processor. It incorporates a rich set of system and application peripherals and standard interfaces in order to provide a single-chip solution for a wide range of compute-intensive applications that require maximum functionality at minimum power consumption. The AT91RM9200 incorporates a high-speed on-chip SRAM workspace and a low-latency external bus interface (EBI) for seamless connection to whatever configuration of off-chip memories and memory-mapped peripherals is required by the application. The EBI incorporates controllers for synchronous DRAM (SDRAM), Burst flash and Static memories and features specific circuitry facilitating the interface for NAND flash/SmartMedia and Compact flash.
