GENERAL DESCRIPTION

The W561xxx is one of the derivatives of the BandDirector

voice synthesizers, one 4-CH Melody generator, and one shared ROM.

The muti-tasking operation for voice synthesis and 4-CH Melody generation is implemented by

dedicated H/W that can output the speech voice in parallel with the background music. With the 4 bit

kernel, which can execute instructions of up to 12 KIPS (Kilo-Instructions Per Second), and high

quality dual speaker output, you will be amazed at the possible applications. W561xxx provides you

with a total solution in one chip.

In addition, the W561xxx's user-friendly development environment can effectively reduce your design

period and help you easily tool your projects by yourself with the ICE and emulation kit.

There are 10 kinds of W561xxx IC bodies (see table below).
