The ASB is designed for maximum performance. It interfaces the processor with the on-chip 32-bit memories and the external memories and devices by means of the External Bus Interface (EBI). The APB is designed for accesses to on-chip peripherals and is optimized for low power consumption. The AMBA Bridge provides an interface between the ASB and the APB. An on-chip Peripheral Data Controller (PDC) transfers data between the on-chip USARTs/SPI and the on- and off-chip memories without processor intervention. Most importantly, the PDC removes the processor interrupt handling overhead and significantly reduces the number of clock cycles required for a data transfer. It can transfer up to 64K contiguous bytes without reprogramming the starting address. As a result, the performance of the microcontroller is increased and the power consumption reduced. The AT91M63200 peripherals are designed to be easily programmable with a minimum number of instructions. Each peripheral has a 16K byte address space allocated in the upper 3M bytes of the 4G byte address space. Except for the interrupt controller, the peripheral base address is the lowest address of its memory space. The peripheral register set is composed of control, mode, data, status and interrupt registers. To maximize the efficiency of bit manipulation, frequently written registers are mapped into three memory locations. The first address is used to set the individual register bits, the second resets the bits and the third address reads the value stored in the register. A bit can be set or reset by writing a one to the corresponding position at the appropriate address. Writing a zero has no effect. Individual bits can thus be modified without having to use costly read-modifywrite and complex bit manipulation instructions. All of the external signals of the on-chip peripherals are under the control of the parallel I/O controller. The PIO controller can be programmed to insert an input filter on each pin or generate an interrupt on a signal change. After reset, the user must carefully program the PIO Controller in order to define which peripheral signals are connected with offchip logic. The ARM7TDMI processor operates in little-endian mode in the AT91M63200 microcontroller. The processor's internal architecture and the ARM and Thumb instruction sets are described in the ARM7TDMI datasheet. The memory map and the on-chip peripherals are described in detail in the datasheet entitled "AT91M63200 Datasheet" (Literature No. 1028). Electrical and mechanical characteristics are documented in a datasheet entitled "AT91M63200 Electrical and Mechanical Characteristics" (Literature No. 1090). The ARM Standard In-Circuit-Emulation debug interface is supported via the ICE port of the AT91M63200 via the JTAG/ICE port when JTAGSEL is low. IEEE JTAG boundary scan is supported via the JTAG/ICE port when JTAGSEL is high. PDC: Peripheral Data Controller The AT91M63200 has an 8-channel PDC dedicated to the three on-chip USARTs and to the SPI. One PDC channel is connected to the receiving channel and one to the transmitting channel of each peripheral. The user interface of a PDC channel is integrated in the memory space of each USART channel and in the memory space of the SPI. It contains a 32-bit address pointer register and a 16-bit count register. When the programmed data is transferred, an end-of-transfer interrupt is generated by the corresponding peripheral. See the USART section and the SPI section for more details on PDC operation and programming. Power Supplies The AT91M63200 has two kinds of power supply pins: * VDDCORE pins, which power the chip core * VDDIO pins, which power the I/O lines This allows core power consumption to be reduced by supplying it with a lower voltage than the I/O lines. The VDDCORE pins must never be powered at a voltage greater than the supply voltage applied to the VDDIO pins. Typical supported voltage combinations are shown in the following table: Pins VDDCORE VDDIO 6 AT91M63200 Typical Supply Voltages 3.0V or 3.3V 3.0V or 3.3V 2.0V 5.0V 3.0V or 3.3V 3.0V or 3.3V AT91M63200 EBI: External Bus Interface The EBI generates the signals that control the access to the external memory or peripheral devices. The EBI is fully programmable and can address up to 64M bytes. It has eight chip selects and a 24-bit address bus, the upper four bits of which are multiplexed with a chip select. The 16-bit data bus can be configured to interface with 8or 16-bit external devices. Separate read and write control signals allow for direct memory and peripheral interfacing. The EBI supports different access protocols, allowing single clock cycle memory accesses. The main features are: * External memory mapping * Up to 8 chip select lines * 8- or 16-bit data bus * Byte write or byte select lines * Remap of boot memory * Two different read protocols * Programmable wait state generation * External wait request * Programmable data float time MPI: Multi-Processor Interface The AT91M63200 features a second bus interface that is dedicated to parallel data exchange with an external processing device. The MPI features a 1K byte dual-port RAM memory and memory access arbitration logic. The ARM processor core and the external processor can both read and write to the dual-port RAM memory. AIC: Advanced Interrupt Controller The AT91M63200 has an 8-level priority, individually maskable, vectored interrupt controller. This feature substantially reduces the software and real-time overhead in handling internal and external interrupts. The interrupt controller is connected to the NFIQ (fast interrupt request) and the NIRQ (standard interrupt request) inputs of the ARM7TDMI processor. The processor's NFIQ line can only be asserted by the external fast interrupt request input: FIQ. The NIRQ line can be asserted by the interrupts generated by the on-chip peripherals and the external interrupt request lines: IRQ0 to IRQ3. An 8-level priority encoder allows the customer to define the priority between the different NIRQ interrupt sources. Internal sources are programmed to be level sensitive or edge triggered. External sources can be programmed to be positive or negative edge triggered or high- or low-level sensitive. PIO: Parallel I/O Controller The AT91M63200 features 58 programmable I/O lines. 14 pins on the AT91M63200 are dedicated as general purpose I/O pins. Other I/O lines are multiplexed with on-chip peripheral I/O signals in order to optimize the use of available package pins. The I/O lines are controlled by two separate and identical PIO controllers (PIOA and PIOB). Each PIO controller also provides an internal interrupt signal to the Advanced Interrupt Controller (AIC). USART: Universal Synchronous/Asynchronous Receiver/Transmitter The AT91M63200 provides three identical, full-duplex, universal synchronous/asynchronous receiver/transmitters that interface to the APB and are connected to the Peripheral Data Controller. The main features are: * Programmable baud rate generator * Parity, framing and overrun error detection * Line break generation and detection * Automatic echo, local loopback and remote loopback channel modes * Multi-drop mode: address detection and generation * Interrupt generation * Two dedicated peripheral data controller channels * 5-, 6-, 7-, 8- and 9-bit character length SPI: Serial Peripheral Interface The AT91M63200 features an SPI, which provides communication with external devices in master or slave mode. The SPI has four external chip selects that can be connected to up to 15 devices. The data length is programmable, from 8- to 16-bit. As for the USART, a 2-channel PDC is used to move data directly between memory and the SPI without CPU intervention for maximum real-time processing throughput. 7 TC: Timer/Counter PMC: Power Management Controller The AT91M63200 features two identical Timer/Counter blocks, each containing three identical 16-bit timer counter channels. Each channel can be independently programmed to perform a wide range of functions, including frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width modulation. Each Timer/Counter channel has 3 external clock inputs, 5 internal clock inputs, and 2 multi-purpose input/output signals that can be configured by the user. Each channel drives an internal interrupt signal that can be programmed to generate processor interrupts via the Advanced Interrupt Controller (AIC). Each Timer Counter block features two global registers that act upon all three TC channels. The Block Control Register allows the three channels to be started simultaneously with the same instruction. The Block Mode Register defines the external clock inputs for each Timer/Counter channel, allowing them to be chained. The Power Management Controller allows optimization of power consumption. The PMC enables/disables the clock inputs to most of the peripherals as well as to the ARM processor core. When the ARM core clock is disabled, the current instruction is processed before the clock is stopped. The clock can be re-enabled by any enabled interrupt or by a hardware reset. When a peripheral clock is disabled, the clock is immediately stopped. When the clock is re-enabled, the peripheral resumes action where it left off. Due to the static nature of the design, the contents of the on-chip RAM and registers for which the clocks are disabled remain unchanged. WD: Watchdog Timer The AT91M63200 features an internal watchdog timer, which can be used to guard against system lock-up if the software becomes trapped in a deadlock. 8 AT91M63200 SF: Special Function The AT91M63200 provides registers that implement the following special functions: * Chip identification * RESET status AT91M63200 Ordering Information Max Speed (MHz) Operating Power Supply Range 25 2.7V to 3.6V (Core) 2.7V to 5.5V (I/Os) Ordering Code AT91M63200-25AC AT91M63200-25AI 12 1.8V to 3.6V (Core) 2.7V to 3.6V (I/Os) RAM (Bytes) Package 2K TQFP 176 Operating Temperature Range Commercial (0C to 70C) Industrial (-40C to 85C) AT91M63200-12AC-1.8 Commercial (0C to 70C) AT91M63200-12AI-1.8 Industrial (-40C to 85C) 9 Package Outline TQFP 176 Table 3.
