1. Dream DSP Array Overview

The SAM3703 is a new member of the SAM3000 family of sound synthesis/processing ICs that

uses the DSP array technology. It is designed for superior quality sound processing. The 16-bit

processor has new instructions and a C compiler for quicker reliable firmware development. Total

compatibility is maintained with the other members of the family. Applications written for the

SAM3703 can be burned into the built-in Flash memory. This memory has specific features to

avoid external read of the coded data, thus ensuring very effective copy protection.

The minimum configuration for a product is SAM3703 + Codec. An external SDRAM/DDR-SDRAM

is needed if 8k internal RAM is not sufficient for extended delay line buffers, like high-quality

reverb.
