5704PIA-DK

5704PIA-DK is a high quality stand-alone evaluation board based on SAM5704 (AUDIO & MUSIC MULTI-DSP PROCESSOR). The SAM5704 can be used in 6 different hardware configurations for different applications. On 5704PIA-DK board the SAM5704 is running in the hardware configuration dedicated to digital pianos and keyboard instruments built around low cost Quad SPI memory components. Samples are stored in Quad SPI Flash and read from it in Quad I/O Read Mode (100MHz) through the SAM5704 Sample Cache Controller to reach 81-voice polyphony. Octal SPI is even possible with 2 Quad SPI devices.
