Pro-Audio Multiple Purpose Processor


Full Description

The SAM3816 is a sound synthesis/processing IC that uses the DSP array technology.

The SAM3816 includes sixteen 24-bit DSPs, a 24-bit Audio Router and a general-purpose 16-bit processor with new instructions and a C compiler for quicker reliable firmware development.

Its high performance and flexibility with 16-input/16-output channels enables implementation of multi- task audio applications in professional products such as digital audio interfaces or high range musical instrument.

A variety of I/Os, including USB 2.0 Full Speed, DDR SDRAM, SDR SDRAM, Wave ROM, NAND Flash and DataFlash® are provided.

Sampling rates up to 144 kHz at 24 bits are supported.

On-chip Flash memory allows copy protection of program code and sound banks.

Evaluation Board SAM3816-E and SAM3816-DK are available for this product.

Development Kit SAM3816-C-PDK (comprising SAM3303-DK development Board and software CD Rom) is available for this product.
