The SAM9733 is a low-cost derivative of the SAM9407 and SAM9503. It retains thesame high-quality synthesis with polyphony up to 64 voices. The SAM9733 maximumwavetable memory is 4 MB and the ISA bus communication is through a standardMPU-401. The SAM9733 is delivered in an industry-standard 100-lead plastic quadflat pack package (PQFP100).

The highly-integrated architecture of the SAM9733 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 SAM9733 on-chip memorymanagement unit (MMU) allows the synthesis/DSP and the control processor to shareexternal ROM and/or RAM memory devices. An intelligent peripheral I/O interfacefunction handles other I/O interfaces, such as the ISA PC bus, the on-chip MIDIUART, and the Codec control interface, with minimum intervention from the controlprocessor
