DESCRIPTION

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It 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), a 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.

SPECIFICATION

  • Microcontroller: AT91SAM3X8E
  • Operating Voltage: 3.3V
  • Recommended Input Voltage: 7-12V
  • Min-Max Input Voltage: 6-20V
  • Digital I/O Pins: 54 (of which 12 provide PWM output)
  • Analog Input Pins: 12
  • Analog Outputs Pins: 2
  • Total DC Output Current on all I/O lines: 130 mA
  • Flash Memory: 512 KB all available for the user applications
  • SRAM: 96 KB (two banks: 64KB and 32KB)
  • Clock Speed: 84 MHz.

MEMORY

The SAM3X has 512 KB (2 blocks of 256 KB) of flash memory for storing code. The bootloader is pre-burned in the factory from Atmel and is stored in a dedicated ROM memory. The available SRAM is 96 KB in two contiguous banks of 64 KB and 32 KB. 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.

INPUT & OUTPUT 

  • Digital I/O: pins from 0 to 53
  • Each of the 54 digital pins on the Due can be used as an input or output, using pinMode(),digitalWrite(), and digitalRead() functions. They operate at 3.3 volts. Each pin can provide (source) a current of 3 mA or 15 mA, depending on the pin, or receive (sink) a current of 6 mA or 9 mA, depending on the pin. They also have an internal pull-up resistor (disconnected by default) of 100 KOhm. In addition, some pins have specialized functions:
  • Serial: 0 (RX) and 1 (TX)
  • Serial 1: 19 (RX) and 18 (TX)
  • Serial 2: 17 (RX) and 16 (TX)
  • Serial 3: 15 (RX) and 14 (TX)  Used to receive (RX) and transmit (TX) TTL serial data (with 3.3 V level). Pins 0 and 1 are connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.
  • PWM: Pins 2 to 13  Provide 8-bit PWM output with the analogWrite() function. the resolution of the PWM can be changed with the analogWriteResolution() function.
  • SPI: SPI header (ICSP header on other Arduino boards)  These pins support SPI communication using the SPI library. The SPI pins are broken out on the central 6-pin header, which is physically compatible with the Uno, Leonardo and Mega2560. The SPI header can be used only to communicate with other SPI devices, not for programming the SAM3X with the In-Circuit-Serial-Programming technique. The SPI of the Due has also advanced features that can be used with the Extended SPI methods for Due.
  • CAN: CANRX and CANTX These pins support the CAN communication protocol but are not yet supported by Arduino APIs.
  • "L" LED: 13  There is a built-in LED connected to digital pin 13. When the pin is HIGH, the LED is on, when the pin is LOW, it's off. It is also possible to dim the LED because the digital pin 13 is also a PWM output.
  • TWI 1: 20 (SDA) and 21 (SCL)
  • TWI 2: SDA1 and SCL1.  Support TWI communication using the Wire library. SDA1 and SCL1 can be controlled using the Wire1 class provided by the Wire library. While SDA and SCL have internal pull-up resistors, SDA1 and SCL1 have not. Adding two pull-up resistor on SDA1 and SCL1 lines is required for using Wire1.
  • Analog Inputs: pins from A0 to A11  The Due has 12 analog inputs, each of which can provide 12 bits of resolution (i.e. 4096 different values). By default, the resolution of the readings is set at 10 bits, for compatibility with other Arduino boards. It is possible to change the resolution of the ADC withanalogReadResolution(). The Due’s analog inputs pins measure from ground to a maximum value of 3.3V. Applying more than 3.3V on the Due’s pins will damage the SAM3X chip. The analogReference() function is ignored on the Due.
