W567CP260
16-CHANNEL SPEECH+MELODY PROCESSOR
(BandDirectorTM Series)
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 ( doesnt support W567Cxx6
items)

Notes:

2. The block (2): The low-pass filter circuit is necessary for VDD stability, in order to avoid VDDSPK noise.
3. The block (3): The capacitor, 4.7uF, shunted between VDD and GND is necessary for power stability. However, the
value of capacitor depends on the power loading of the application.
4. The typical value of Rosc is 300 Kfor 8MHz and 390 Kfor 6MHz, and the Rosc should be connected to GND
(VSS). Please refer to design guide to get typical Rosc value for each part number.
5. The block (4):The capacitor, 120pF, shunted between OSCIN and VDD is optional for Fosc stability, which can
prevent noise from happening, because it can block the affection of larger current while playing. However, the value
of capacitor depends on the application (100pF~200pF is recommended)
6. The block (5): The Rs value is suggested of 270~ 1Kto limit large DAC output current flowing into transistor.
7. The above application circuit is for reference only. No warranty for mass production.
