Arduino Due R3 ARM Cortex-M3 Board By Generic

PRODUCT DESCRIPTION / SPECIFICATIONS

​PRODUCT 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, 12 analog inputs, 4 UARTs ,a 84 MHz clock, an USB OTG capable connection, 2 DAC, 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.

The SAM3X has 512KB of flash memory for storing code. 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 can be accessed directly as a flat addressing space.

FEATURES:

• A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock.
• CPU clock at 84Mhz
• 96KBytes of SRAM
• 512KBytes of flash memory for code
• A DMA controller, that can relieve the CPU from doing memory intensive tasks.
