16-CHANNEL SPEECH+MELODY PROCESSOR
1. GENERAL DESCRIPTION
The W567CP260 is a powerful microcontroller (uC) dedicated to speech and melody synthesis
applications. With 8Mbit embedded OTP, the help of 8-bit microprocessor, it can synthesize 16-
channel speech+melody simultaneously.
The two channels of synthesized speech can be in different kinds of format, for example ADPCM
and MDPCM. The W567CP260 can provide 16-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 W567CP260 is very suitable for high-quality and
sophisticated scenario applications.
The W567CP260 provides at most 24 bi-directional I/Os, maximum 512 bytes RAM, IR carrier,
Serial Interface Management, and 32KHz-Divider for more 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, W567CP260 also provides PWM mode output to save power during playback and Watch
Dog Timer to prevent latch-up situation occurring.
W567CP260 is the OTP chip for the W567C series. It covers the correspondent items in the
duration of less than 260 seconds and provide only one DAC/PWM ( doesn’t support W567Cxx6
W567CP260 support items:
*: 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.
