W567JXXX
1. GENERAL DESCRIPTION
The W567Jxxx 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 W567Jxxx 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 W567Jxxx can provide 6-channel high-quality WinMelodyTM , which can emulate
the characteristics of musical instruments, such as piano and violin. The output of speech/melody
channels are mixed together through the on-chip digital mixer to produce colorful effects. With these
hardware resources, the W567Jxxx is very suitable for high-quality and sophisticated scenario
applications.
The W567Jxxx provides at most 24 bi-directional I/Os, 256 bytes RAM , IR carrier, Serial Interface
Management and more sophisticated applications, such as interactive toys, cartridge toys and final
count down function. 3 LED output pins with 256-level control means that numerous combination of
RGB colors may result in a versatility of colorful effects. In addition, W567Jxxx also provides PWM
mode output to save power during playback and Watch Dog Timer to prevent latch-up situation
occurring.
The W567Jxxx family contains several items with different playback duration as shown below.

Note:
*: The duration time is based on 5-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.
