N567K081 Datasheet | Nuvoton Technology

DESCRIPTION The N567K081 is a powerful microcontroller (u C) dedicated to speech and melody synthesis applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the N567K081 can synthesize 6-channel speech & melody simultaneously. The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The N567K081 can provide 6-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 N567K081 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 N567K081 is very suitable for high-quality and sophisticated scenario applications. The N567K081 provides 254KB ROM, 24 I/O pins, 384 bytes RAM, IR Tx carrier, Serial Interface Manager (SIM), and S/W libraries to meet requirements from sophisticated applications like interactive toys and educational applications. The N567K081 provides PWM mode audio output to save power during playback and Watch Dog Timer to prevent from code runaway conditions. Furthermore, the N567K081 enhances system ESD contact immunity, builds in LDO to drive Spi Flash directly, and provides LVD and LVR options. It also has bandgap reference inside to control deviation w.r.t. temperature within +/-3% for voltage references over 0C ~ 70C.
