1. Description
The ATSAM2553 integrates into a single chip a SAM core (64-slots DSP + 16-bit pro-
cessor), a 32K x 16 RAM, an LCD display interface and a scanner allowing direct
connection to velocity sensitive keyboards, switches, LEDs and sliders. With addition
of a single external ROM or Flash and a stereo DAC, a complete low cost musical
instrument can be built, including reverb and chorus effects, parametric equalizer, sur-
round effects, orchestrations, pitch bend, wheel controller, without compromising on
sound quality. The ATSAM2553 is housed in a standard 128-lead LQFP package.
