AT91RM9200

AT91RM9200 Atmel | SMART ARM-based Embedded MPU DATASHEET Description The Atmel® | SMART AT91RM9200 is a complete system-on-chip built around the ARM920T™ ARM® Thumb® 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 at lowest cost. 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 CompactFlash. The Advanced Interrupt Controller (AIC) enhances the interrupt handling performance of the ARM920T processor by providing multiple vectored, prioritized interrupt sources and reducing the time taken to transfer to an interrupt handler. The Peripheral DMA Controller (PDC) provides DMA channels for all the serial peripherals, enabling them to transfer data to or from on- and off-chip memories without processor intervention. This reduces the processor overhead when dealing with transfers of continuous data streams. The AT91RM9200 benefits from a generation of PDC which includes dual pointers that significantly s...
