Atmel | SMART AT91RM9200 Datasheet

1 Atmel -1768J-ATARM- AT91RM9200 -Datasheet_0 3-Mar-16 DescriptionThe Atmel | SMART AT91RM9200 is a complete system-on-chip built around theARM920T ARM Thumb processor. It incorporates a rich set of system andapplication peripherals and standard interfaces in order to provide a single-chipsolution for a wide range of compute-intensive applications that require maximumfunctionality at minimum power consumption at lowest AT91RM9200 incorporates a high-speed on-chip SRAM workspace, and alow-latency External Bus Interface (EBI) for seamless connection to whateverconfiguration of off-chip memories and memory-mapped peripherals is requiredby the application.

2 The EBI incorporates controllers for synchronous DRAM(SDRAM), Burst Flash and Static memories and features specific circuitryfacilitating the interface for NAND Flash/SmartMedia and Advanced Interrupt Controller (AIC) enhances the interrupt handlingperformance of the ARM920T processor by providing multiple vectored, prioritizedinterrupt sources and reducing the time taken to transfer to an interrupt Peripheral DMA Controller (PDC) provides DMA channels for all the serialperipherals, enabling them to transfer data to or from on- and off-chip memorieswithout processor intervention.

3 This reduces the processor overhead whendealing with transfers of continuous data streams. The AT91RM9200 benefitsfrom a generation of PDC which includes dual pointers that significantly simplifybuffer set of Parallel I/O (PIO) controllers multiplex the peripheral input/output lineswith general-purpose data I/Os for maximum flexibility in device configuration. Aninput change interrupt, open drain capability and programmable pull-up resistor isincluded on each line. The Power Management Controller (PMC) keeps system power consumption to aminimum by selectively enabling/disabling the processor and various peripheralsunder software control.

4 It uses an enhanced clock generator to provide a selectionof clock signals including a slow clock (32 kHz) to optimize power consumptionand performance at all AT91RM9200 integrates a wide range of standard interfaces including Full Speed Host and Device and Ethernet 10/100 Base-T Media AccessController (MAC), which provides connection to an extensive range of externalperipheral devices and a widely used networking layer. In addition, it provides arich set of peripherals that operate in accordance with several industry standards,such as those used in audio, telecommunication, Flash Card, infrared and SmartCard | SMART ARM-based Embedded MPUDATASHEETAT91RM9200 [ Datasheet ] Atmel -1768J-ATARM- AT91RM9200 - Datasheet_03-Mar-162To complete the offer, the AT91RM9200 benefits from the integration of a wide range of debug features includingJTAG-ICE, a dedicated UART debug channel (DBGU) and an embedded real-time trace.
