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.
