The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. 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 bootloader is preburned in factory from Atmel and is stored in a dedicated ROM memory. The available SRAM is 96KB in two contiguous bank 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. Note: Unlike other Arduino boards, the Arduino 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. Specifications: Microcontroller: AT91SAM3X8E Clock speed: 84MHz Operating voltage: 3.3V Input voltage(recommended): 7V – 12V Input voltage(limits): 6V – 20V Digital I / O pins: 54 (of which 12 provide PWM output) Analog input pins: 12 Analog outputs pins: 2 (DAC) Total DC output current on all I / O lines: 130mA DC current for 3.3V pin: 800mA DC current for 5V pin: 800mA SRAM: 96KB (two banks: 64KB and 32KB) Flash memory: 512KB all available for the user applications Package Contents: 1 x Arduino DUE R3 Board 1 x USB Cable
