Description

The ATSAM2133B is a low-cost derivative of the ATSAM97xx series. It retains the

same high-quality synthesis with up to 64-voice polyphony. The ATSAM2133B maxi-

mum wavetable memory is 16 MB and the parallel communication is via a standard

MPU-401. The integrated 32K x 16 RAM allows for high-quality effects without addi-

tional components.

The highly integrated architecture of the ATSAM2133B combines a specialized high-

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

pose 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 MPU port, the on-chip MIDI UART,

and the Codec control interface, with minimum intervention from the control processor.
