Description
The ATSAM3303 is a member of the new ATSAM3000 family that uses the DSP array
technology. The ATSAM3303 includes three 24-bit DSPs, a 24-bit Audio Router and a
general-purpose 16-bit on-chip CISC microcontroller. Its high performance and flexibil-
ity allow implementation of professional-quality audio applications, such as MP3
decoding, Wavetable synthesis, effect processing and mixing. A variety of I/Os, includ-
ing external Wave ROM, SmartMedia and DataFlash are provided. Sampling rates up
to 96 kHz at 24 bits are supported.
