Description The 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 Compact Flash. 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 new generation of PDC which includes dual pointers that simplify significantly buffer chaining. The set of Parallel I/O (PIO) controllers multiplex the peripheral input/output lines with generalpurpose data I/Os for maximum flexibility in device configuration. An input change interrupt, open drain capability and programmable pull-up resistor is included on each line. The Power Management Controller (PMC) keeps system power consumption to a minimum by selectively enabling/disabling the processor and various peripherals under software control. It uses an enhanced clock generator to provide a selection of clock signals including a slow clock (32 kHz) to optimize power consumption and performance at all times. The AT91RM9200 integrates a wide range of standard interfaces including USB 2.0 Full Speed Host and Device and Ethernet 10/100 Base-T Media Access Controller (MAC), which provides connection to a extensive range of external peripheral devices and a widely used networking layer. In addition, it provides an extensive set of peripherals that operate in accordance with several industry standards, such as those used in audio, telecom, Flash Card, infrared and Smart Card applications. To complete the offer, the AT91RM9200 benefits from the integration of a wide range of debug features including JTAG-ICE, a dedicated UART debug channel (DBGU) and an embedded real time trace. This enables the development and debug of all applications, especially those with real-time constraints. 2 AT91RM9200 Summary 1768IS–ATARM–30-Sep-05 AT91RM9200 Summary 2.

Using PIOC pins increases the number of general-purpose I/O lines available but prevents 32-bit memory access. • PIOD, available in the 256-ball BGA package option only, multiplexing outputs of the peripheral set and the ETM port. Each PIO Controller controls up to 32 lines. Each line can be assigned to one of two peripheral functions, A or B. The tables in the following paragraphs define how the I/O lines of the peripherals A and B are multiplexed on the PIO Controllers A, B, C and D. The two columns “Function” and “Comments” have been inserted for the user’s own comments; they may be used to track how pins are defined in an application. The column “Reset State” indicates whether the PIO line resets in I/O mode or in peripheral mode. If equal to “I/O”, the PIO line resets in input with the pull-up enabled so that the device is maintained in a static state as soon as the NRST pin is asserted. As a result, the bit corresponding to the PIO line in the register PIO_PSR (Peripheral Status Register) resets low. If a signal name is in the “Reset State” column, the PIO line is assigned to this function and the corresponding bit in PIO_PSR resets high. This is the case for pins controlling memories, either address lines or chip selects, and that require the pin to be driven as soon as NRST raises. Note that the pull-up resistor is also enabled in this case.

However, there is no clock control associated with these peripheral IDs. 30 AT91RM9200 Summary 1768IS–ATARM–30-Sep-05 AT91RM9200 Summary 4.5 Product Memory Mapping A first level of address decoding is performed by the Memory Controller, i.e., by the implementation of the Advanced System Bus (ASB) with additional features. Decoding splits the 4G bytes of address space into 16 areas of 256M bytes. The areas 1 to 8 are directed to the EBI that associates these areas to the external chip selects NC0 to NCS7. The area 0 is reserved for the addressing of the internal memories, and a second level of decoding provides 1M bytes of internal memory area. The area 15 is reserved for the peripherals and provides access to the Advanced Peripheral Bus (APB). Other areas are unused and performing an access within them provides an abort to the master requesting such an access. 4.5.1 External Memory Mapping Figure 4-3.

In the AT91RM9200, only the USART1 implements these signals, named DTR1, DSR1, DCD1 and RI1. The USART0, USART2 and USART3 do not implement all the modem signals. Only RTS and CTS (RTS0 and CTS0, RTS2 and CTS2, RTS3 and CTS3, respectively) are implemented in these USARTs for other features. Thus, programming the USART0, USART2 or the USART3 in Modem Mode may lead to unpredictable results. In these USARTs, the commands relating to the Modem Mode have no effect and the status bits relating the status of the modem signals are never activated. 4.6.2 Timer Counter The Timer Counter 0 to 5 are described with five generic clock inputs, TIMER_CLOCK1 to TIMER_CLOCK5. In the AT91RM9200, these clock inputs are connected to the Master Clock (MCK), to the Slow Clock (SLCK) and to divisions of the Master Clock. Table 4-9 gives the correspondence between the Timer Counter clock inputs and clocks in the AT91RM9200. Each Timer Counter 0 to 5 displays the same configuration. Table 4-9.
