N567G161 Datasheet | Nuvoton Technology

DESCRIPTION The N567Gxxx 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 N567Gxxx can synthesize 4-channel speech+melody simultaneously. The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The N567Gxxx can provide 4-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 N567Gxxx 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 N567Gxxx is very suitable for high-quality and sophisticated scenario applications. The N567Gxxx 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, N567Gxxx also provides PWM mode audio output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring. The N567Gxxx family contains several items with different playback duration as shown below: (@4-bit NM4 algorithm, 6 KHz sampling rate) Item - Duration Item - Duration N567G030 34 sec. N567G240 233 sec. N567G041 44 sec. N567G280 272 sec. N567G080 84 sec. N567G330 311 sec. N567G120 124 sec. - - N567G121 124 sec. N567G160 158 sec. - - N567G161 158 sec. N567G200 192 sec. - - N567G201 192 sec. Note: - : The duration time is based on 4-bit NM4 at 6 KHz sampling rate. The firmware library and timber library have been excluded from user’s ROM space for the duration estimation. Note: - - : N567G121/161/201 are modified from...
