Smart Home Audio(325)


The N567H120 is a powerful microcontroller (μC) dedicated to speech and melody synthesis applications.  With the help of the embedded 8-bit microprocessor & dedicated H/W, the N567H120 can synthesize 8-channel speech+melody simultaneously.

The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The N567H120 can provide 8-channel high-quality wavetable melody, which can emulate the characteristics of musical instruments, such as piano and violin.  More colorful melody effects are implemented in N567H120, such as modulation, vibrato, and pitch-bending etc.  The output of speech/melody channels are mixed together through the on-chip digital mixer to produce colorful effects.  With these hardware resources, the N567H120 is very suitable for high-quality and sophisticated scenario applications.

The N567H120 provides at most 24 I/O pins, 384 bytes RAM , IR carrier, Serial Interface Management (SIM) , and more sophisticated applications, such as interactive toys, cartridge toys and final count down function. In addition, N567H120 also provides PWM mode audio output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.
