... Product Overview 7.1 Power Supply The AT91M40800 microcontroller has a unique type of power supply pin – VDD. The VDD pin supplies the I/O pads and the device core. The supported voltage range on V 7.2 Input/Output Considerations The AT91M40800 microcontroller I/O pads are 5V-tolerant, enabling them to interface with external 5V devices without any additional components. Thus, the devices accept 5V (3V) on the inputs even if powered at 3V (2V). For further information, refer to the “ ...

... In any of these address spaces, the ARM7TDMI operates in Little-Endian mode only. 7.6.1 Internal Memories The AT91M40800 microcontroller integrates 8K bytes of internal SRAM. All internal memories are 32 bits wide and single-clock cycle accessible. Byte (8-bit), half-word (16-bit) or word (32-bit) accesses are supported and are executed within one cycle. Fetching Thumb or ARM instruc- tions is supported and internal memory can store twice as many Thumb instructions as ARM ones ...

... The ARM vectors (Reset, Abort, Data Abort, Prefetch Abort, Undefined Instruction, Interrupt, Fast Interrupt) are mapped from address 0x0 to address 0x20. In order to allow these vectors to be redefined dynamically by the software, the AT91M40800 microcontroller uses a remap com- mand that enables switching between the boot memory and the internal primary SRAM bank addresses ...

... Peripheral Data Controller The AT91M40800 microcontroller has a 4-channel PDC dedicated to the two on-chip USARTs. One PDC channel is dedicated to the receiver and one to the transmitter of each USART. The user interface of a PDC channel is integrated in the memory space of each USART. It con- tains a 32-bit Address Pointer Register (RPR or TPR) and a 16-bit Transfer Counter Register (RCR or TCR) ...

... PIO: Parallel I/O Controller The AT91M40800 microcontroller has 32 programmable I/O lines. Six pins are dedicated as general-purpose I/O pins. Other I/O lines are multiplexed with an external signal of a peripheral to optimize the use of available package pins. The PIO controller enables generation of an inter- rupt on input change and insertion of a simple input glitch filter on any of the PIO pins ...
