It is a multi-channel speech controller and it is an 8-bit single chip microprocessor. It contains RAM, ROM, I/Os, interrupt function and 12-bit high-quality DA. For CPU power consideration, this chip not only built-in an 8-Bits CPU but also a Wave Processing Unit (WPU). All the wave-table melody play are handled by this WPU, CPU should set-up the property initial value before wave-table melody playing. Besides, according to improvement of the CPU power, most of standard MIDI format can be acceptable through the MIDI to Melody convert software.
