W588C121

The W588C121 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, W588C121 performs two channels of speech with high sound quality.  Also, a user-friendly tool is provided for W588C121 to define output patterns easily for multi-tasking applications. W588C121 can synthesize two-channel speech in different formats, for example ADPCM and MDPCM. Regarding synthesized melody, W588C121 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 W588C121 series can accomplish multi-tasking requirements easily and make toys more complicated than traditional PowerSpeech.

W588C121 provides at most 16 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. W588C121 also provides Low Voltage Reset and a Watch Dog Timer to prevent a hang-up situation from occurring.
