1. Description
The ATSAM3308B is a member of the new ATSAM3000 family that uses the DSP
array technology. The ATSAM3308B includes eight 24-bit DSPs, a 24-bit Audio
Router and a general-purpose 16-bit on-chip CISC microcontroller. Its high perfor-
mance and flexibility 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 digi-
tal mixing. A variety of I/Os, including external Wave ROM, SmartMedia^® and
DataFlash^® are provided. Sampling rates up to 96 kHz at 24 bits are supported.
