The W588C020 is a powerful embedded 8-bit microprocessor (uP) dedicated to speech and melody synthesis applications. With flexible firmware synthesis and new technology in PWM and DAC, W588C020 performs two channels of speech with high sound quality.  Also, a user-friendly tool is provided for W588C020 to define output patterns easily for multi-tasking applications. W588C020 can synthesize two-channel speech in different formats, for example ADPCM and MDPCM. Regarding synthesized melody, W588C020 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 W588C020 series can accomplish multi-tasking requirements easily and make toys more complicated than traditional PowerSpeech.

W588C020 provides at most 12 bi-directional I/Os, an IR carrier, and 3 output pins with 256-level control, an 8-bit timer and up to 128 bytes RAM. W588C020 also provides Low Voltage Reset and a Watch Dog Timer to prevent a hang-up situation from occurring.
