N567HXXX
1. GENERAL DESCRIPTION
The N567Hxxx is a powerful microcontroller (uC) dedicated to speech and melody synthesis applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the N567Hxxx 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 N567Hxxx 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 N567Hxxx series, 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 N567Hxxx is very suitable for high-quality and sophisticated scenario applications.
The N567Hxxx provides at most 32 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. 3-pair LED output pins with 64-level control means that numerous bination of RGB colors may result in a versatility of colorful effects. In addition, N567Hxxx also provides PWM mode audio output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.
The N567Hxxx family contains several items with different playback duration as shown below: (@4-bit NM4 algorithm, 6 KHz sampling rate)
