Description The ATSAM3703 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 piler for quicker reliable firmware development. Total patibility is maintained with the other members of the family. Applications written for the ATSAM3703 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 ATSAM3703 + Codec. An external SDRAM/DDR-SDRAM is needed if the 8K internal RAM is not sufficient for extended delay line buffers, such as high-quality reverb. 6237A- DRMSD- 29-May-06 2. DSP Array Block Diagram ..
