Due AT91SAM3X8E ARM Cortex-M3

The Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. The Due Arduino AT91SAM3X8E ARM Cortex-M3 Board is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.

Getting Started:

  • The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with an AC-to-DC adapter or battery to get started.
  • The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.
  • The SAM3X has 512KB (2 blocks of 256KB) of flash memory for storing code. The bootloader is pre-burned in a factory from Atmel and is stored in a dedicated ROM memory.
  • The available SRAM is 96KB in two contiguous banks of 64KB and 32KB. All the available memory (Flash, RAM, and ROM) can be accessed directly as a flat addressing space.
  • It is possible to erase the Flash memory of the SAM3X with the onboard erase button. This will remove the currently loaded sketch from the MCU. To erase, press and hold the Erase button for a few seconds while the board is powered.
  • Due follows the 1.0 pinout:
  • TWI: SDA and SCL pins that are near to the AREF pin.
  • The IOREF pin which allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V.
  • An unconnected pin, reserved for future use

Note: Unlike other Arduino boards, the Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board.

1. What are the applications of ARM Cortex M3?

  • ARM Cortex M3 processor is very well suited for highly deterministic real-time applications Microcontroller Programming in Embedded and low-cost platforms such as industrial control systems, automotive body systems, wireless networking and sensors, and so on.

2. What features does the ARM Cortex M3 core possess?

  • The Cortex-M3 processor is a 32-bit processor, with a 32-bit wide data path, register bank, and memory interface. A total of 13 general-purpose registers, two stack pointers, a link register, a program counter, and a number of special registers, including a program status register, are available.

3. Is ARM Cortex-M3 a microcontroller or microprocessor?

  • The Arm Cortex-M3 is a microcontroller. The 32-bit Arm Cortex-M3 core microcontroller is designed for high-performance, real-time processing in cost-constrained applications and can handle complex tasks. Any Arm Cortex-M3 microcontroller offers high scalability combined with an optimal trade-off between performance and cost.

4. How do I power Due?

  • The Due can be powered either by USB or by an external power supply. The power source is automatically selected. An AC-to-DC adapter (wall-wart) or a battery can provide external (non-USB) power. A 2.1mm center-positive plug can be plugged into the board's power jack to connect the adapter.

5. Is Due better than mega?

  • The speed of the processor for the due board is much faster compared to the mega board. The processor used in the due board is considered the fastest processor compared to other boards. The other difference between the due board and the mega board is the size of the memory.
