Description
The ATSAM3308 is a member of the new ATSAM3000 family that uses the DSP array
technology. The ATSAM3308 includes eight 24-bit DSPs, a 24-bit Audio Router and a
general-purpose 16-bit on-chip CISC microcontroller. Its high performance and flexibil-
ity with 8-input/8-output channels enables implementation of audio applications in
professional-quality sound production such as MP3 decoding with time stretch and
pitch control, concurrent Wavetable synthesis, effect processing and digital mixing. A
variety of I/Os, including external Wave ROM, SmartMedia^® and DataFlash^® are pro-
vided. Sampling rates up to 96 kHz at 24 bits are supported.
