Description

The ATSAM2533 is a low cost derivative of the ATSAM97xx series. It retains the

same high quality synthesis with up to 64 voices polyphony. The ATSAM2533 maxi-

mum wavetable memory is 32 MBytes and the parallel communication is through a

standard 8-bit port.

The integrated 32K x 16 RAM allows for high quality effects without additional

components.

The highly integrated architecture from ATSAM2533 combines a specialized high per-

formance RISC-based digital signal processor (Synthesis/DSP) and a general

purpose 16-bit CISC-based control processor on a single chip. An on-chip memory

management unit (MMU) allows the synthesis/DSP and the control processor to share

external ROM and/or RAM memory devices. An intelligent peripheral I/O interface

function handles other I/O interfaces, such as the 8-bit parallel, the on-chip MIDI
