1. GENERAL DESCRIPTION
The N567Kxxx 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 N567Kxxx 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 N567Kxxx 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 N567Kxxx 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 N567Kxxx is very suitable for high-quality and sophisticated scenario applications.
The N567Kxxx provides at most 32 I/O pins, 384 bytes RAM , IR carrier, Serial Interface Management (SIM), Serial Peripheral Interface bus (SPIO) and more sophisticated applications, such as interactive toys, cartridge toys and final count down function. 6 LED output pins with 64-level control means that numerous combination of RGB colors may result in a versatility of colorful effects. In addition, N567Kxxx also provides PWM mode output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.
The N567Kxxx family contains several items with different playback duration as shown below: (@4-bit MDPCM algorithm, 6 KHz sampling rate)
Item N567K040 N567K080 N567K120 N567K160 N567K200 N567K240 Duration 45 sec. 87 sec. 131 sec. 168 sec. 205 sec. 248 sec.
Item N567K280 N567K330
Duration 291 sec. 333 sec.
Note: *: The duration time is based on 4-bit MDPCM at 6 KHz sampling rate. The firmware library and timber library have been excluded from user’s ROM space for the duration estimation.
