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. 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.
ARM offers the Keil Microcontroller Development Kit (MDK-ARM) for ARM powered microcontrollers. It features the industry-standard compiler from ARM, the Keil µVision IDE, and sophisticated debug and data trace capabilities. MDK-ARM offers tailored support for all Cortex-M processor-based devices, and is the recommended solution for students working with standard ARM-based MCU devices. We suggest that students and universities download the free evaluation version of the tools, which offers all the features of the standard version, but with a 32 KByte object code/data limit.
