W567SXXX
1. GENERAL DESCRIPTION
The W567Sxxx 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 W567Sxxx
can synthesize 8-channel speech+melody simultaneously.
The two channels of synthesized speech can be in different kinds of format, for example ADPCM and
MDPCM. The W567Sxxx can provide 8-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. The mixer is
further processed to drive dual speakers with stereo effects. With these hardware resources, the
W567Sxxx is very suitable for high-quality and sophisticated scenario applications.
The W567Sxxx is also capable of transmitting infrared (IR) signals with on-chip carrier generator. As a
result, toys can be designed to interact with each other for more play values. A serial interface can be
supported as external memory for memory expansion or content-updateable applications.
Besides, the W567Sxxx is equipped with a 4-channel Analog-to-Digital Converter (ADC). With ADC, a
toy can respond to environment conditions such as temperature or pressure via sensory devices.
Therefore, toys with ADC can behave vividly than ever before.
The W567Sxxx family contains several items with different playback duration as shown below: (@5-bit
MDPCM algorithm, 6 KHz sampling rate)

FUNCTION
IC reset input, low active.
32 KHz crystal oscillator with divider for time-keeping application
32 KHz crystal oscillator with divider for time-keeping application
Main-clock oscillation input. Only Ring type is used. Connect to GND via the
oscillation resistor.
General input port with pull-high selection. Each 2 input pins can be
programmed to generate interrupt request and used to release IC from
STOP mode.
IP0[3:0] are used as the input of ADC. IP0.0 is the input pin of channel 0
and IP0.3 is the input pin of channel 3, and so on.
General input/output pins. When used as output pin, it can be opendrain
or CMOS type and it can sink 8mA for high-current applications. When
used as input pin, there may have a pull-high option and generate interrupt
request to release IC from STOP mode.
When BP0[7] is used as output pin, it can be the IR transmission carrier for
IR applications.
General input/output pins. When used as output pin, it can be opendrain
or CMOS type. When used as input pin, there may have a pull-high option
and generate interrupt request to release IC from STOP mode.
When serial interface is enabled, BP1[6:4] are used as serial interface pins.
General input/output pins. When used as output pin, it can be opendrain
or CMOS type. When used as input pin, there may have a pull-high option
