W562XXX Datasheet, PDF (2/8 Pages) Winbond – DUAL-TONE MELODY WITH VOICE SYNTHESIZER (BandDirector Series)

W562XXX
1. GENERAL DESCRIPTION
The W562xxx is one of the derivatives of the BandDirector^TM family. It consists of a 4-bit µC, two voice
synthesizers, one Dual-Tone Melody generator, 38 KHz carrier output for IR transmission and one
ROM shared ROM.
The muti-tasking operation for voice synthesis and Dual-Tone Melody generation is implemented by
dedicated H/W that can output the speech voice in parallel with the background music. The 4 bit
kernel, which executes instructions of up to 12 KIPS (Kilo-Instructions Per Second) can offer
customers a great deal of flexibility to achieve various kind of program controls for different
applications.
In addition, the W562xxx's user-friendly development environment can effectively reduce your design
period and help you easily tool your project by yourself with the W56xxx ICE and emulation kit.
There are 9 kinds of W562xxx IC bodies. (See table below).

Possible applications are:
• Programmed voice synthesis with background music or speech.
• I/O interactive voice synthesis to accompany background music or speech.
• Q&A games.
• Edutainment toys.
• Remote toys.
2. FEATURES
• Multi-engine processor parallel management with µC, speech and Dual-Tone Melody.
− µC // (Synthesizer1 or Dual-Tone Melody) // Synthesizer2 (//: in parallel )
− µC, with basic ALU, 64-nibble RAM (including 8 working registers) and an 8-bit timer.
The W561 & W562 user RAM initialization value is not constant. It is random. So, user must
initial constant value.
− Synthesizer1 capable of voice syntheses with Sample rate @ 4.8/6/8/12 KHz
− Synthesizer2, same as synthesizer1.
− Dual-tone Melody D/A output with 3 level volume control
