1. Description
The ATSAM3703 is a new member of the SAM3000 family of sound synthesis/pro-
cessing 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 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.
