W567CXXX
1. GENERAL DESCRIPTION
The W567Cxxx 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 W567Cxxx
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 W567Cxxx 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 W567Cxxx is very suitable for high-quality and sophisticated scenario
applications.
The W567Cxxx 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, W567Cxxx also provides PWM mode output to save power during playback and Watch
Dog Timer to prevent latch-up situation occurring.
The W567Cxxx family contains several items with different playback duration as shown below.

FUNCTION
IC reset input, low active.
Main-clock oscillation input. When Ring type is used, connects Rosc
between OSCIN and VSS to generate the system clock frequency.
Reserved one 100pF~200pF capacity to Vdd from OSCin pin to make
Ring frequency stability
When use Xtal, it is Xtal IN.
Main-clock oscillation output only for Xtal.
32 KHz crystal oscillator with divider for time-keeping application
32 KHz crystal oscillator with divider for time-keeping application
General input/output pins. When used as output pin, it can be opendrain
or CMOS type and it can sink 25mA 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 BP07 is used as output pin, it can be the IR transmission carrier for
IR applications. BP04~BP06 are used as 3 LED outputs with 256-level
control.
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, and set memory type as W55F/W551C,
BP14~BP16 are used to be an interface with the external memory,
W55Fxx or W551Cxxx. If set memory to SPI flash, BP13~BP16 are used
to be an interface.
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.
PWM driver positive output or Current type DAC output
PWM driver negative output
PWM driver positive output or Current type DAC output
PWM driver negative output
Test input, internally pulled low. Do not connect during normal operation.
