The W588C006 is a powerful embedded 8-bit microprocessor (uP) dedicated to speech and melody synthesis applications. With flexible firmware synthesis and new technology in PWM, W588C006 performs two channels of speech with high sound quality.  Also, a user-friendly tool is provided for W588C006 to define output patterns easily for multi-tasking applications. W588C006 can synthesize two-channel speech in different formats, for example ADPCM and MDPCM. Regarding synthesized melody, W588C006 can provide 2-tracks of Tone melody (T-melody) , or 1-track of High-Quality melody (HQ-melody) that can emulate the characteristics of musical instruments. In general, the W588C006 series can accomplish multi-tasking requirements easily and make toys more complicated than traditional PowerSpeech.

W588C006 provides at most 8 bi-directional I/Os, an IR carrier, and 3 output pins with 256-level control, an 8-bit timer and up to 96 bytes RAM. W588C006 also provides Low Voltage Reset and a Watch Dog Timer to prevent a hang-up situation from occurring.
