Typical Application

Digital Piano / Keyboard


Integrated Digital Musical Instrument

The SAM2653 integrates into a single chip a proprietary DREAM®  DSP core (64-slots DSP + 16-bit microcontroller), a 32k x 16 RAM, an LCD display interface and a scanner allowing direct connection to velocity sensitive keyboards, switches, LEDs, sliders. With addition of a single external ROM or FLASH, a complete low cost musical instrument can be built, including reverb and chorus effects, parametric equalizer, orchestrations, pitch bend, wheel controller, without compromising on sound quality.
