Description

The ATSAM9753 integrates into a single chip an ATSAM97xx core (64-slot DSP and

16-bit processor), a 32K x 16 RAM, an LCD display interface and a scanner, allowing

direct connection to velocity-sensitive keyboards, switches, LEDs and sliders. With the

addition of a single external ROM or Flash and a stereo DAC, a complete low-cost

musical instrument can be built that includes reverb and chorus effects, parametric

equalizer, surround effects, orchestrations, pitch-bend and wheel controller, without

compromising on sound quality. The ATSAM9753 is packaged in a standard 144-lead

TQFP package.
