The Due has a 32‐bit ARM core that can outperform typical 8‐bit microcontrollerboards. 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. • a DMA controller, that can relieve the CPU from doing memory intensive tasks
