W567Bxxx

Datasheet
Description	The W567Bxxx 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 W567Bxxx can synthesize 4-channel speech+melody simultaneously. The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567Bxxx can provide 4-channel high-quality *WinMelody?* , 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 W567Sxxx is very suitable for high-quality and sophisticated scenario applications. The W567Bxxx 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.
Features	Wide range of operating voltage: 8 MHz @ 3.0 volt ~ 5.5 volt 4 MHz @ 2.4 volt ~ 5.5 volt Power management: 4 ~ 8 MHz system clocks, with Ring type and Crystal type Stop mode for stopping all IC operations Provides up to 8 inputs, 8 outputs and 24 I/O pins Current-type Digital-to-Analog Converter (DAC): (8+2)-bit resolution with programmable output current F/W speech synthesis with multiple format support: ADPCM/MDPCM/PCM Up to 4 speech synthesis¹ channels at programmable sample rate 4 melody channels that can emulate characteristics of musical instruments 4-input/8-bit-resolution Mixer can mix the speech and melody signals flexibly Built-in IR carrier generation circuit for simplifying firmware IR application Built-in 5 timers for speech/melody synthesis and general purpose applications Built-in 8*7 multiplier Built-in Watch-Dog Timer (WDT) Built-in Low-Voltage-Reset (LVR) Built-in Serial Interface Manager (SIM) in W567B030 ~ B260 Support PowerScript for developing codes in easy way Full-fledged development system Source-level ICE debugger Event synchronization mechanism Compatible with W566B/C & W588S system User-friendly GUI environment Available package form: (COB is essential)
