DUE ATSAM3X8E Microcontroller ARM Cortex M3 Development Board
The Iteaduino DUE is a microcontroller board based on the Atmel SAM3X8E ARM Crotex-M3 core. It is the improvement board based on the Ardui-no DUE. It has 54 digital IO pins 12 analog inputs 4 UARTs a 84MHz clock an USB OTG capable connection 2 DACs 2 IIC a power jack an SPI header a reset button and an erase button. The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. The Due is compatible with all Ardui-no compatible shields that work at 3.3V and are compliant with the 1.0 Ardui-no compatible pinout.
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.
The Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are: A 32-bit core that allows operations on 4 bytes wide data within a single CPU clock.
- CPU Clock at 84Mhz.
- 96 KBytes of SRAM.
- 512 KBytes of Flash memory for code.
